Activating Environment In Virtualenvwrapper

i installed virtualenv and virtualenvwrapper and with this command i created an environment: mkvirtualenv cv it works and after creating i was in the new environment. right now i

Solution 1:

To activate an environment, we use workon command.

workon cv

If you forget the virtualenv name, you can just type:

workon

And you will see a list of available environments.

Solution 2:

virtualenvwrapper works best if you use mkproject instead of mkvirtualenv. This makes a virtualenv and a project directory to put your files that use the virtualenv. After that you can use workon to switch back to your virtualenv and project.

Solution 3:

I ran into the same problem because I misread the docs and accidentally specified the directory where I put my repos as my $WORKON_HOME, so virtualenvwrapper couldn't find my virtualenvs.

$WORKON_HOME should actually be where your virtualenvs live (I like to make mine at ~/.virtualenvs). This is where the command mkvirtualenv creates the virtualenv for your project. Set this environment variables in your .bashrc (or equivalent), make sure your new $WORKON_HOME directory exists, and then make a new virtualenv. That should fix the problem.

Solution 4:

Read the Docs

workon

List or change working virtual environments

$ workon cv

Solution 5:

I too faced the same problem. So first I uninstalled virtualenvwrapper using,

$ sudo pip uninstall virtualenvwrapper

Then I performed the documentation steps again with some changes this time. You can also do the same, it will work.

Install Steps

1. $ sudo pip install virtualenvwrapper

2. Now create a directory to store your virtual environment

   $ mkdir ~/.virtualenvs

3. Now,

   $ export WORKON_HOME=~/.virtualenvs

4. Now you have to open .bashrc file and add one line to it.

   So, to do this first copy the line written below and then run, $ nano .bashrc And now paste it at the end of the script

   . /usr/local/bin/virtualenvwrapper.sh

   This will add virtualenvwrapper.sh to .bashrc

5. Now run ,

   source /usr/local/bin/virtualenvwrapper.sh

6. Finally run to reload .bashrc,

   source ~/.bashrc

7. Finally you can use mkvirtualenv and workon commands without any problem.

Hope it helps.
