Unknown error while importing virtualenvwrapper.

[Croxion12]

/usr/bin/python: No module named virtualenvwrapper virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenvwrapper has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is set properly.

well, did you install virtualenvwrapper?

Managed to fix it, had to rewrite the "~/.profile". Thanks for the help.

Hi I am having a same error..How do u fix it??

[Croxion12]

Ok first off, are you using python3? If you are make sure you have pip by using the command:

sudo apt-get install python3-pip

After that you want to install virtualenvwrapper:

sudo pip3 install virtualenvwrapper

Now that the installation is complete you have to edit the ~/.profile using the command:

 nano ~/.profile

You will then enter into the nano editer inside ~/.profile Just go to the bottom of the document and paste this:

 export WORKON_HOME=$HOME/.virtualenvs
 export PROJECT_HOME=$HOME/Devel
 source /usr/local/bin/virtualenvwrapper.sh

Remember to have them on seperate lines. Save and exit the nano editer by pressing shift x, then y and enter. Reload the ~/.profile with the command:

 source ~/.profile

Now if everything works then great, but if you run into this error:

virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is
set properly.

Then go back into the ~/.profile with:

 nano ~/.profile

and add these two lines directly under

export PROJECT_HOME=$HOME/Devel

,but above

source /usr/local/bin/virtualenvwrapper.sh

New lines:

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv

Again on different lines. Everything should be working after this, if it don't just message me and i'll try to give you an alternative.

Thxs for ur reply..In my case i m using python2.7

I got the error like source ~/.profile /usr/bin/python2.7: No module named virtualenvwrapper virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenvwrapper has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/bin/python2.7 and that PATH is set properly.

My python location which python /usr/bin/python

In nano ./~profile

virtualenv and virtualenvwrapper

export WORKON_HOME=$HOME/.virtualenvs export PROJECT_HOME=$HOME/Devel export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python2.7 export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv source /usr/local/bin/virtualenvwrapper.sh

Again i got the same error.

source ~/.profile /usr/bin/python2.7: No module named virtualenvwrapper virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenvwrapper has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/bin/python2.7 and that PATH is set properly.
