Python/IPython ImportError: no module named site
TRY to unset your python path...
In Linux/Mac, you can use these commands:
unset PYTHONPATHunset PYTHONHOME
Change the location of the standard Python libraries. By default, the libraries are searched in prefix/lib/pythonversion and exec_prefix/lib/pythonversion, where prefix and exec_prefix are installation-dependent directories, both defaulting to /usr/local.
When PYTHONHOME is set to a single directory, its value replaces both prefix and exec_prefix. To specify different values for these, set PYTHONHOME to prefix:exec_prefix.
Try to clean up your PYTHONHOME
:
user$ export PYTHONHOME=
As for installing matplotlib, I would recommend the following:
sudo apt-get install python-matplotlib
(details here)
you can unset PYTHONHOME
to use the system default, or export PYTHONHOME=/usr
to specify the prefix, to which Python will append '/lib/python2.7' (or whatever version it happens to be) to locate its libraries.
if you export PYTHONHOME=/usr/lib/python2.7
, Python looks for libraries in the nonexistent folder /usr/lib/python2.7/lib/python2.7
.
and if you export PYTHONHOME=
, you are telling Python to look for lib
in the current working directory:
