Re: Python not able to find package but it is installed

Consider this output

[root@cluster ~]# pip --version
pip 9.0.1 from /opt/rocks/lib/python2.6/site-packages/pip-9.0.1-py2.6.egg 
(python 2.6)
[root@cluster ~]# easy_install --version
distribute 0.6.10
[root@cluster ~]# find /opt -name python
/opt/rocks/lib/graphviz/python
/opt/rocks/bin/python
/opt/rocks/usr/bin/python
/opt/python
/opt/python/bin/python

/opt/rocks/bin/pip

[root@cluster ~]#




So, yes there are multiple versions of python and it seems that the search 
location of pip and python are different. I will try to modify the path to see 
what is what.

But

$ find /opt -name openpyxl
/opt/rocks/lib/python2.6/site-packages/openpyxl



So, your pip knows about a search path that python doesn't know.
That can have a number of reasons still and one would be Pavol's 
suggestion that your pip command may run on a different python than the 
python you invoke with the commmand 'python'. However, this would 
require that you have two separate installs of python2.6 on your system, 
which sounds rather unlikely.


Another possibility is that pip picks up additional directories from a 
pip config file somewhere. To check this you could compare


pip show openpyxl
to
pip show --isolated openpyxl
(which would ignore any pip config file or environment variable)

or (since I don't remember what commands your rather old version of pip 
will support):


pip list vs pip list --isolated
(which should give all installed packages pip knows about with and 
without additional config settings.

In case there are two python environment it could create mess.

Maybe problem started by adding /opt/rocks/bin into PATH manually? If
it is true I rather remove it, then  and then .

Re: Python not able to find package but it is installed

[Pavol Lisy]

What is output from

$ pip ---version
$ easy_install --version

?

Maybe you have two pythons and only one pip?

$ find /opt -name python
$ find /usr -name python

$ find /opt -name pip
$ find /usr -name pip

Re: Python not able to find package but it is installed

[Mahmood Naderan via Python-list]

Well, on rocks there exist multiple pythons. But by default the active is 2.6.6

$ python -V
Python 2.6.6


I have to say that the script doesn't modify sys.path. I only use sys.argv[] 
there

I can put all dependent modules in my project folder but that will be dirty.

Mahmood

In addition to checking sys.path as suggested, also try running

python -V

to check if it's Python2.6 as reported by pip or if you have two 
different versions of Python installed.

Re: Python not able to find package but it is installed

[Nagy László Zsolt]

Do you have /opt/rocks/lib/python2.6/site-packages on sys.path?

Does your exread2.py file manipulate sys.path in any way?
