How to activate virtualenv

Question

I have been through search and tried various alternatives without success and spent several days on it now - driving me mad   Running on Red Hat Linux with Python 2 5 2 Began using most recent Virtualenv but could not activate it  I found somewhere suggesting needed earlier version so I have used Virtualenv 1 6 4 as that should work with Python 2 6   It seems to install the virtual environment ok   necrailk server6     python virtualenv-1 6 4 virtualenv py virtual New python executable in virtual bin python Installing setuptools            done  Installing pip               done    Environment looks ok   necrailk server6     cd virtual  necrailk server6   virtual   dir bin  include  lib   Trying to activate   necrailk server6   virtual     bin activate  bin    Permission denied    Checked chmod   necrailk server6   virtual   cd bin  necrailk server6 bin   ls -l total 3160 -rw-r--r--    1 necrailk biz12        2130 Jan 30 11 38 activate -rw-r--r--    1 necrailk biz12        1050 Jan 30 11 38 activate csh -rw-r--r--    1 necrailk biz12        2869 Jan 30 11 38 activate fish -rw-r--r-   Problem  so I changed it   necrailk server6 bin   ls -l total 3160 -rwxr--r--    1 necrailk biz12        2130 Jan 30 11 38 activate -rw-r--r--    1 necrailk biz12        1050 Jan 30 11 38 activate csh -rw-r--r--    1 necrailk biz12        2869 Jan 30 11 38 activate fish -rw-r--r--    1 necrailk biz12        1005 Jan 30 11 38 activate this py -rwxr-xr-x    1 necrailk biz   Try activate again   necrailk server6   virtual     bin activate  bin    Permission denied    Still no joy

The problem there is the  bin   command  That s really weird  since   should always be a link to the directory it s in   Honestly  unless   is a strange alias or function  I don t even see how it s possible   It s also a little unusual that your shell doesn t have a   builtin for source  One quick fix would be to just run the virtualenv in a different shell   An obvious second advantage being that instead of having to deactivate you can just exit    bin bash --rcfile bin activate  If your shell supports it  you may also have the nonstandard source command  which should do the same thing as    but may not exist   All said  you should try to figure out why your environment is strange or it will cause you pain again in the future   By the way  you didn t need to chmod  x those files  Files only need to be executable if you want to execute them directly  In this case you re trying to launch them from    so they don t need it

You forgot to do source bin activate where source is a executable name  Struck me first few times as well  easy to think that manual is telling  execute this from root of the environment folder     No need to make activate executable via chmod

Probably a little late to post my answer here but still I ll post  it might benefit someone though   I had faced the same problem    The main reason being that I created the virtualenv as a  root  user But later was trying to activate it using another user   chmod won t work as you re not the owner of the file  hence the alternative is to use chown  to change the ownership   For e g      If you have your virtualenv created at  home abc ENV  Then CD to  home abc   and run the command   chown -Rv  user-to-whom-you want-change-ownership   folder filename whose ownership needs to be changed   In this example the commands would be   chown -Rv abc ENV  After the ownership is successfully changed you can simply run source  ENV bin   activate and your should be able to activate the virtualenv correctly
