I believe this has been removed many Sage versions ago. You can still
just define it yourself:

sage: def SmallGroup(*args):
: return libgap.SmallGroup(*args)
sage: SmallGroup(6,2)


(PS. don't use gap.* prefix, use libgap.* prefix, as above, as gap.*
functions are deprecated - libgap.*
provides a much faster adn more reliable interface)

Re: [sage-support] Apparently Sage lost Python

[Anita Rojas]

Thanks. It did work! It has recovered almost all his previous capabilities.
Although, I still do not know how to add the SmallGroup Data base
directly to sage.

Currently it is working by doing, for instance:
g=gap.SmallGroup(6,2)

And before this Catalina's upgrade I used to write just
g=SmallGroup(6,2)

I am deeply grateful to everyone who helped me, and to SAGE developers.

Best,

(I hope MacOS does not mess with my running softwares again...)

Forgot one step. Run this:

Re: [sage-support] Apparently Sage lost Python

[Anita Rojas]

Thanks a lot. But I also got:

sage: libgap.eval('LoadPackage("PackageManager")')

fail

 Should I add (or install) some gap package inside SageMath folder?

Sorry

The following says the `kbmag` GAP package cannot be loaded.

sage: libgap.eval('LoadPackage("kbmag")')
fail

It fails to load because it is not installed in Sage's GAP.

Thankfully, installing packages has become a pleasant task
thanks to Michael Torpey's `PackageManager` GAP package.

Load the `PackageManager` GAP package, whose job
is to help you install further packages:

sage: libgap.eval('LoadPackage("PackageManager")')
true

and let it install `kbmag` with this command:

sage: libgap.eval('InstallPackage("kbmag")')
true

Now loading `kbmag` works:

sage: libgap.eval('LoadPackage("kbmag")')
true

The `kbmag` package is now loaded, ready to
try and make rewriting systems confluent.

This worked! Thanks
Now I have troubles calling gap. I used to do

sage:  libgap.eval('LoadPackage("kbmag")')

but now I got

Re: [sage-support] Apparently Sage lost Python

[Anita Rojas]

Hi. Thanks. Sage 9.0 is working on my mac, still with some issues.

I have to run in a terminal:


sudo spctl --master-disable
~/Applications/SageMath/sage -n jupyter

(without "sudo..." it does not open because some archives can not be
checked)

My older routines don't work. They use GAP and I got the message:


*“gap-bin” no se puede abrir porque no se puede verificar el desarrollador.*
*macOS no puede verificar si esta app está libre de software malicioso.*

(Same as before: gap-bin can not be executed because it can not be verified
and it could be a malware)

I can not even use the line G=SmallGroup(2,1)

I thought it was a problem of security and I gave full access to disk to
sage, I work under this "sudodisable", but still..

Well. Thanks again for all your support. I am sure the main problem is that
I am barely qualified in anything more than a user level of mac.

Best,
Anita

the recent Sage 9.1 betas have ability to use system Python3 rarher
than build Python.
But then there would not be "SageMath" in some paths at all.

Re: [sage-support] Apparently Sage lost Python

[rana-aere]

Dear Dima,

I found something strange in this error message.

anirojas@MacBook-de-Anita ~ % /Applications/SageMath/sage --notebook=export 
--list

File "/Applications/SageMath/local/bin/sagenb-export"

File 
"/Applications/SageMath/local/lib/python3.7/site-packages/sagenb_export/cmdline.py",

File 
"/Applications/SageMath/local/lib/python3.7/site-packages/sagenb_export/actions.py",

File 
"/Applications/SageMath/local/lib/python3.7/site-packages/sagenb_export/actions.py",

File 
"/Applications/SageMath/local/lib/python3.7/site-packages/sagenb_export/sagenb_reader.py"


On MacOS, normally, we see

-

/Applications/SageMath-9.0.app/sage --notebook=export --list

/Applications/SageMath-9.0.app/Contents/Resources/sage/local/lib/python3.7/site-packages/sagenb_export/...



I do not understand why "Contents/Resources/sage/" disappeared.

More strangely, functions defined in these files are actually executed.

Is it possible some problem in setting PATH leads to python3 bundled with 
Catalina controls

Sagemath instead of python3.7 included in Sagemath?


I do not have Catalina installed. So, I cannot verify anything on it.

I only heard Catalina now has python3 not python2.

The default shell changed to zsh instead of bash.

Re: [sage-support] Apparently Sage lost Python

[rana-aere]

I am sorry for I might have given you extra work, which produced nothing.
I agree it is not a good time to use SageMath on Catalina.

Re: [sage-support] Apparently Sage lost Python

[Anita Rojas]

Thanks a lot for your support and patience but I gave up. I can not
succeed. There are too many difficulties that I am not going to be able of
solving: My older routines lost, my files with computations and examples. I
do not know how to recover them. Perhaps I will try again in next future,
with less anxiety and more energy.
Thanks again.
Best regards

Re: [sage-support] Apparently Sage lost Python

[Anita Rojas]

Thanks, but I installed 8.9 and it did not work. Back again to point 0.
I did the line "sudodisable" but I still get:

*“python2.7” no se puede abrir porque no se puede verificar el
desarrollador.*

(meaning that python2.7 can not open because it could be a malware)

Re: [sage-support] Apparently Sage lost Python

[rana-aere]

I guess it is about the page of title "Home".
We do not have access to sagenb notebooks.
Instead we have access to jupyter notebooks.
For the current situation, you do not have any noebooks.
That is why no notebook is listed in the page.
You can try "New" button at the upper right corner below the grey 
horizontal line.
If you play with some little program in the new notebook,
it might be a good chance to test upgrading sagenb notebooks.

This "upgrade" is only possible from command line.
The two relevant "sage --notebook=export --list" and "sage 
--notebook=export ipynb TARGETFILENAME admin:NN". The former prints a 
list of sagenb notebooks.
An example is here.

```

Unique ID   | Notebook Name

---

admin:0 | Save 30% by Sagemath  (~/Manuals/SageTutorial9.0.pdf)

admin:1 | "Rabbit's population" $F_n$ is like $((1+\sqrt{5})/2)^n$!

admin:2 | Integral #1: $f(x)=\frac{1}{\sqrt{1-x^2}}$, $|x| < 1$.

admin:3 | Integral #2: why is f(x) = x * sqrt(1-x^2), (x in [-1,1]) 
easier?

admin:4 | Oval body & `tail' of @rana-aerea

admin:5 | Calculus of log|x|, x > 0.

admin:6 | mycalc

admin:7 | mycalc

```


The other command upgrades the notebook.

For example,

"sage --notebook=export ipynb mycalc-a admin:6"

converts the notebook with title "mycalc" with the unique id "admin:6".

It is possible some notebooks of yours have unique id of the form "guest:0"

or some other "user name". I guess 

"sage --notebook=export ipynb guestnotebook guest:0"

also works.

Re: [sage-support] Apparently Sage lost Python

[rana-aere]

Yes, version <= 8.9 is the solution for now.
If the number of notebooks is not too large, upgrading sagenb notebooks to 
jupyter notebooks
might be a good idea.
In the next release, the error messages will not be missing.
In that time please try "sage --notebook=export --list"
and "sage --notebook=export ipynb TARGETFILENAME admin:NN"
for upgrading notebooks.

Yes. Thanks. I manage in less than enough in MacOS. I will try to install

At least on Linux, it must be jupyter, not Jupyter

Once again, to get an idea what goes wrong, we need to see the
messages you get in the terminal after you started this.

9.1 ?
It's not ready yet.

Thanks. I tried "sage -n Jupyter", and my browser opened but without
success in entering SAGE.
I will install SAGA 8.1 to see if it works.
Here is the message I got once typing "sage -n":

Re: [sage-support] Apparently Sage lost Python

[rana-aere]

I guess your computer is left vulnerable.
So you should use
```
sudo spctl --master-enable
```

We are fixing slow start-up of Sagemath and also problems of permissions.
SageMath-8.9 is OK for MacOS upto MacOS Mojave.
SageMath-9.0 needs techniques for installation on MacOS Mojave.
Many people complains problems of SageMath-9.0 on MacOS Catalina.
I only understood two or three symptoms reported but I located one 
essential problem.

So, we are in a rather transient situation.

For the user's of sagenb notebook, I'd rather recommend to use SageMath-8.9 
while
waiting for SageMath get OK with Catalina. I think you are in this category.

For MacOS freak, I recommend to try the following procedure in the same 
account:
(This works for MacOS Mojave. On the other hand, no one reported it to work 
on Catalina.)
(1) Copy SageMath-9.0 from disk-image to /Applications. Do not double click 
it at this moment.
(2) Open /Applications/Utilities/Terminal.app
(3) In the terminal window, issue the following command
```
myhome$ /Applications/SageMath-9.0.app/sage
```
(4) Quit sage after the sage-prompt asks you for input something.
(5) Diable verification by "sudo spctl --master-disable".
(6) Double click /Applications/SageMath-9.0.app
(7) Specify your folder for Sagemath when a dialogue asks it.
 This folder is something close to the folder tree  ~/.sage of 
notebooks.
 But it must be different from ~/.sage.
 Sagemath does not start-up on Catalina if this folder is not specified 
at the dialogue.
(8) If Sagemath opened a web-page of jupyter notebook
 and you verify this page accept programs of Sagemath (e.g. 
print("hello") ),
 then quit Sagemath by the menu.
(9) Use " sudo spctl --master-enable" to restart protection.

I guess this explanation gives an impression of a gap between (7) and (8).
This is because we are still fighting the problem behind (7).

If you are in this category, I welcome claims from you.

Alternatively, if you want to go to new versions of Sagemath,
please wait for Sagemath-9.1.

As well,

you might try running

sage -n jupyter

which should directly launch a jupyter notebook

Re: [sage-support] Apparently Sage lost Python

[Anita Rojas]

Thanks. Still not working :(
Now I got:

500 : Internal Server Error

in Chrome browser.
What should I do?
Sorry and deep thanks.

 I am installing a new version of sage. I have received several times
 (more than 20) a message like

 macOS no puede verificar el desarrollador de la app “_
 sha3.cpython-37m-darwin.so”. ¿Seguro que quieres abrirla?

 Which means that the developer is unknown and it asks me if I want to
 open it. It is a warning of malware. I have authorize its installation, but
 I have been doing this one by one...is it ok? or usual?

 Thanks, and I am sorry for bothering you but I use sage regularly and I
 do not want to lose it.
 Best,
 Anita

 Probably a MacOS update broke your Sage installation.

 If so, reinstalling might be the only  known way to fix this.

Re: [sage-support] Apparently Sage lost Python

[Anita Rojas]

Thanks. I did:

sudo spctl --master-disable

and it worked. I have a question: Did I leave my computer vulnerable by
doing so?

Second: I was used to use notebook() but it did not work.

Deep thanks for your help
Anita

yes, this is an issue due to Apple "improving" their security in the latest
MacOS.

I believe there are instructions on
https://ask.sagemath.org/question/49568/new-sagemath-90-installation-not-running-on-catalina-sagemath-87-worked-fine/

and perhaps other posts there.

[sage-support] Apparently Sage lost Python

[Anita Rojas]

Hi! I am far away of being a OSX guru, but I managed to get my SAGE 
working. 

It use to work properly but now I got the following message:


Error: Tried to use Sage's Python which was not yet installed.

If this was called from an spkg-install script for another 

package you should add $(PYTHON) as a dependency in 

build/pkgs//dependencies


I looked for solutions but I could not find answers. I would appreciate 
help.


Best,

Anita
