Installing virtualenvwrapper on macOS Sierra - "-bash: /usr/local/bin/virtualenvwrapper.sh: No such file or directory" error I'm a bit of a newbie to Python and definitely to virtual environments and Django. I want to install Django but it first recommends a virtualenv / virtualenvwrapper. A video I am watching recommends installing virtualenvwrapper so I just tried this, following these instructions:

https://virtualenvwrapper.readthedocs.io/en/latest/install.html#basic-installation
and
https://stackoverflow.com/questions/15101559/terminal-where-is-the-shell-start-up-file

I first ran 

pip install virtualenvwrapper


which seemed to work fine. It generated some messages, ending with:

I then had to follow the "shell startup" guidelines which mentioned adding these lines to be shell startup file:

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


I did this. Once I run $ source ~/.bash_profile on terminal, I am presented with this error:

-bash: /usr/local/bin/virtualenvwrapper.sh: No such file or directory

After searching online, a forum post recommended that I run:

which virtualenvwrapper.sh

and this gives me the result:

/Users/rishi/anaconda3/bin/virtualenvwrapper.sh

Note I have Anaconda installed for some (previous) learning. I now want to install/learn Django.

Searching online, one person recommended to copy the virtualenvwrapper.sh from the one directory to the /usr/local/bin/ directory. It also seems like I should have done this with sudo - i.e. should I have run the following? 

sudo pip install virtualenvwrapper


I'm super confused - I never was good with server/installing stuff so I'd really appreciate guidance on how/what to install correctly in order to get my virtual environment working, and then hopefully I can use Django. 

Perhaps you may recommend 


just copying the Anaconda virtualenvwrapper.sh  file as suggested? 
Or if I should install again using sudo then please let me know how to uninstall virtualenvwrapper (that I just installed) so I can re-install it, 


or please simply let me know the steps I should follow as I don't want to mess anything up, if I haven't already!

UPDATE

I copied the file from Anandonda to the main folder as explained above, and then ran this. The following messages were generated, and now I seem to be good, I can use the workon command for example.

You have a mix of pythons on your machine. I would stick to one.

In this case I would stick to anaconda.

SO edit your path so that anaconda is first on the path before /usr/local/bin and /usr/bin

Test by running 

 which python  


You should get

/Users/mark/anaconda3/bin/python


If a 2 rather than 3 you have python2,7 and I would switch to 3.

You can now use virtulenv etc as they are part of python 3.6 (the current 3.x version) see the python docs You should use venv now not what your tutorial shows https://docs.python.org/3/library/venv.html

However as you are using anaconda you can use conda insteaf of venv, You will find most things already installed (I use conda as it provides prebuilt C libraries when needed, pip etc can be more complex and also could require Xcode) https://conda.io/docs/user-guide/getting-started.html The django install is at https://anaconda.org/anaconda/django
