Python virtualenv has changed sys.path permanently

Question

I have activated a python virtualenv (dev) for one of my projects. However, don't know what happened, it looks like it has changed the path permanently. I cannot access my global packages. When I print sys.path it shows me paths related to virtualenv (dev) which is no more activated. When I run pip list, it shows me packages installed for virtualenv (dev) and not the ones install globally (c:\\python27\\Lib\\sitepackages). Any idea what must have gone wrong? And how do I reset sys.path?

I checked out RegistryKey (HKEY_LOCAL_MACHINE\\SOFTWARE\\Python\\PythonCore\\2.7\\PythonPath) and Environment variables, everything looks okay. Any light on this issue would be helpful...

Answer 1

Your default environment variables may be wrong in path, since the default path must point to the python globally.

Try this:

1. Start menu > Run > 'sysdm.cpl' > Enter
2. Search for the tab 'Advanced'
3. Finally 'Environment Variables'

Edit the system variable ' Path '

Carefully and search for the python path, just change it to the global paths instead.

c:\\python27\\Lib\\site-packages\\PyQT4 (usually) c:\\python27 c:\\python27\\scripts

Hope I could help.
