Django VirtualEnv设置-'setuptools pip wheel失败，错误代码为-11'

Question

I'm following a setup tutorial for Django where I have to set up a virtual environment in my folder. I didn't have virtualenv , so I did sudo pip install virtualenv and got this message after it was installed:

Chriss-MacBook-Air:trydjango18 cnowak7$ sudo pip install virtualenv
The directory '/Users/cnowak7/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Installing collected packages: virtualenv
Successfully installed virtualenv-13.1.0

After this, I tried creating a virtual environment like in the tutorial with virtualenv . and got this abnormal output:

Chriss-MacBook-Air:trydjango18 cnowak7$ virtualenv .

OSError: Command /Users/cnowak7/Deskt...django18/bin/python3 -c "import sys, pip; sys...d\"] + sys.argv[1:]))" setuptools pip wheel failed with error code -11

So I tried to see if this error would affect my progress in the tutorial, so when I ran source bin/activate , I got this error:

Chriss-MacBook-Air:trydjango18 cnowak7$ source bin/activate
-bash: bin/activate: No such file or directory

I tried uninstalling and reinstalling pip and virtualenv , but this problem persists. Is this possibly because I have every in my Anaconda folder directory? Any help or advice would be appreciated. Thanks.

Answer 1

I ended up solving this problem by going to www.brew.sh and running the following command in my Terminal:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

From my understanding, it basically gave me all the packages and libraries that I was missing that Apple didn't originally give me. I hope this helps for anyone else who was experiencing this same problem.

Answer 2

try this:

sudo easy_install pip

and then:

virtualenv your_virtualenv

Answer 3

I had the same problem as @Rafi. Upon examining error messages after executing

virtualenv .

, I got a clue from this error message:

dyld: Library not loaded: @rpath/libpython3.6m.dylib

Did some search and found out it means bad interactions between virtualenv and Anaconda at this link . This simple solution solved my problem:

pip uninstall virtualenv
conda install virtualenv
