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

Question

我正在遵循Django的设置教程，在该教程中，必须在文件夹中设置虚拟环境。 我没有virtualenv ，所以我做了sudo pip install virtualenv并在安装后得到了此消息：

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.

Collecting virtualenv

Successfully installed virtualenv-13.1.0

之后，我尝试使用virtualenv .在本教程中创建一个虚拟环境virtualenv . 并得到以下异常输出：

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

因此，我尝试查看此错误是否会影响本教程的进度，因此当我运行source bin/activate ，出现了以下错误：

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

我尝试卸载并重新安装pip和virtualenv ，但是此问题仍然存在。 这可能是因为我的Anaconda文件夹目录中有每个目录吗？ 任何帮助或建议，将不胜感激。 谢谢。

我最终通过访问www.brew.sh并在终端中运行以下命令来解决此问题：

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

据我了解，它基本上给了我苹果最初没有给我的所有软件包和库。 我希望这对遇到同样问题的其他人有所帮助。

尝试这个：

sudo easy_install pip

virtualenv your_virtualenv

我和@Rafi有同样的问题。 执行后检查错误消息

virtualenv .

，我从此错误消息中得到了一个线索：

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

做了一些搜索和发现它是指在virtualenv中和巨蟒之间的相互作用不好这个链接 。 这个简单的解决方案解决了我的问题：

pip uninstall virtualenv
conda install virtualenv
