Python virtualenvwrapper problem running the initialization hooks

bash 16.04 python virtualenv virtualenvwrapper

Solution 1

I am using Ubuntu server 16.04, You should also export the python interpreter in which you've installed the the virtualenvwrapper

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export WORKON_HOME=~/.virtualenvs
source /home/vagrant/.local/bin/virtualenvwrapper.sh

Make sure to replace all the paths above according to your own system. Your wrapper script might e.g. be located in /usr/local/bin/virtualenvwrapper.sh instead, or you might use a different interpreter or virtualenvs home, ...

Solution 2

just comment

source /usr/local/bin/virtualenvwrapper.sh

line in

~/.bashrc

file....it worked for me.

Solution 3

In the .bashrc change

VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3

and then make it work in the current shell by

source /usr/local/bin/virtualenvwrapper.sh

Afterwards, change in the virtualenvwrapper.sh

VIRTUALENVWRAPPER_PYTHON="$(command \which python)"

to this

VIRTUALENVWRAPPER_PYTHON="$(command \which python3)"

Solution 4

You probably need to update your PYTHONPATH environment variable. In your .bashrc, before all the virtualenvwrapper variables, add the following line:

export PYTHONPATH=${PYTHONPATH}:/usr/bin

On a fresh install of 16.04, I am trying to install virtualenvwrapper by following this great answer by Gerhard Burger.

after configuring the .bashrc, whenever opening the terminal displays
```
bash: /usr/local/bin/python2.7: No such file or directory
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/local/bin/python2.7 and that PATH is
set properly.
```
the script location is,
```
$ sudo find / -name virtualenvwrapper.sh
[sudo] password for john: 
/usr/local/bin/virtualenvwrapper.sh
```
contents of my .bashrc are,
```
export WORKON_HOME=/home/john/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh
export PIP_VIRTUALENV_BASE=/home/john/.virtualenvs
```
here is my pip freeze
```
cffi==1.5.2
greenlet==0.4.9
pbr==1.10.0
readline==6.2.4.1
six==1.10.0
stevedore==1.15.0
virtualenv==15.0.2
virtualenv-clone==0.2.6
virtualenvwrapper==4.7.1
```
the python interpreter's location,
```
$ which python
/usr/bin/python
```
How do I make it work?

thank you.

  @John My /usr/local/bin indeed doesn't contain python2.7, and I suspect yours doesn't either. which python2.7 says /usr/bin/python2.7, but I have not yet figured out how to tell virtualenvwrapper to look in /usr/bin instead of /usr/local/bin.

  @John Based on virtualenvwrapper.readthedocs.io/en/latest/…, can you add export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python to your .bashrc before source /usr/local/bin/virtualenvwrapper.sh?

  @edwinksl tried it, but it doesn't fix.

  @John How about also adding export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv before source /usr/local/bin/virtualenvwrapper.sh?

  @edwinksl sorry to say, that too doesn't work.

  @John Ah okay. I am not sure what to try next, so I will let others try instead.

  I have the same problem, every time I open the terminal it displays /usr/bin/python3: Error while finding spec for 'virtualenvwrapper.hook_loader' (ImportError: 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/python3 and that PATH is set properly.

VIRTUALENVWRAPPER_PYTHON="$(command \which python3)" worked for me. I think this was because I had two versions of python and it needed to know to pick python3 but it was installed in the homebrew. which python returned /usr/bin/python but which python3 returned /opt/homebrew/bin/python3
