Exploring the virtualenv Error while finding spec for ‘virtualenvwrapper.hook_loader’ (: No module named ‘virtualenvwrapper’)
The error is a very popular python and virtualenv error which occurs when you use virtualenvwrapper.
Beware of mixing between different errors. Please make sure you are dealing with the same error.
#
Error while finding spec for 'virtualenvwrapper.hook_loader' (<class 'ImportError'>: No module named 'virtualenvwrapper')
virtualenvwrapper.sh: There was a problem running the initialization hooks.
#
Bellow we will describe how the error can be solved. With multiple possible solutions.
Solution 1 : edit the ~/.bashrc file when using virtualenvwrapper
We have already established the fact that this is a python and virtualenv error that occurs when you use virtualenvwrapper.
There are many ways to fix the problem, the best option is to edit the ~/.bashrc file. By making sure, the line bellow
#
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python
#
is replaced by this line. Make sure you put your version of python there.
#
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3.9
#
If that does not work, try using only python3 instead of python3.9 for example.
I hope this method helped you get rid of the error. Try the second method if this one fails.
Solution 2 : install virtualenv and virtualenvwrapper before sourcing using : source $HOME/.bashrc
The second method is a step by step method.
First, we should start by running the command bellow
#
sudo apt-get install python3-pip
#
Then we should use pip3 to install both virtualenvwrapper and virtualenv
#
sudo pip3 install virtualenv virtualenvwrapper
#
If go through this entire method and it does not work, please try again and replace the command above with the command bellow instead.
#
sudo pip install virtualenv virtualenvwrapper
#
Finally, you should run this command
#
source $HOME/.bashrc
#
I hope your error is fixed, if not I have another method for you.
Solution 3 : A Combination of the two previous methods
The third method is a mix between the two methods above.
Basically you should follow the steps in Method 2 without using this command.
#
source $HOME/.bashrc
#
Then run the commands in Method 1 , if you did that and nothing has changed.
Try again, but now include the command bellow as the last command of the whole process.
#
source $HOME/.bashrc
#
I hope this Method and the other methods have solved your problem, thank you for reading this post to the end.
