Yeah. Me too. Possibly made easier by having a GUI.
The biggest problem is that the installer does not save the
information necessary to perform the uninstall. A secondary problem
is accounting for dependencies between packages.
A GUI does not help either of these problems. If you can implement
an uninstall in the GUI, you can implement it from the command line.
Another point is to have something like webstart for
java. If I understand how it works, running an application goes like
this: If you open an app and it depends on another package not
installed on your system java goes around and download the missing
modules for you (and stores them in a relative place to the
package or
the user package dir) so the application can run. This would be cool
for python, the problem being that there is no security to guarantee
that those modules are not malicious in any way...
I agree with that strongly.
I very much dislike things that automatically download and install
software. An automatic installer may find a different version of a
supporting package every time I install software on another machine.
if the application asks for the different version then yes it should
download the version that was asked for and installed for that
application. It will only find a different version each time if the
application asks for it.
I keep careful track of what is installed on all my machines. If
the tool automatically installs any version other than the one I
specified, then the tool is working _against_ me. I don't need that.
No it is working like the application writer specified it.
Ideally, there would be a flag that says "if you can't find
something, give me an error -- do not attempt to download/install
anything". But it would be helpful if it can tell me "Package xyzzy
is missing, but you can get it from here:..."
This I agree, it should have a way to ignore some requests or even all
requests of the application that is launched, maybe even have a
configuration file somewhere (or a registry key, or a plist file
depending on the os) that override the default, which I think should
be give the running application the version that it specifies
(standard packaging version rules apply, if it asks for package >=1.0
then any version newer than 1.0 is sufficient)
But this is just a proposition that I think will never be able to work
with python without security or only signed and pre approved packages
on pypi.
