Python + Django : Trouble with setting up mkvirtualenv on macOS

Question

我使用的是 macOS (10.13.3) 并安装了 Python v 3.6.4

我正在尝试按照 Mozilla 文章中的说明进行操作:https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/development_environment

我的流程:

1 which python » /usr/local/bin/python 注意，在此过程中我做了一个符号链接(symbolic link) ln -s/usr/local/bin/python3/usr/local/bin/python

2 python3 -V » Python 3.6.4

PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
export PATH

export WORKON_HOME=$HOME/.virtualenvs

# export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3 # No impact

我的 .bash_profile 文件的完整内容:

# Setting PATH for Python 3.6
# The original version is saved in .bash_profile.pysave

PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
export PATH

export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3
export PROJECT_HOME=$HOME/Devel
source /usr/local/bin/virtualenvwrapper.sh

我猜我的问题与以下内容有关，但我不知道这意味着什么，也不知道如何解决它，有人可以帮助我吗？

ERROR: The executable /Users/myuser/.virtualenvs/my_django_environment/bin/python is not functioning
ERROR: It thinks sys.prefix is '/Library/Frameworks/Python.framework/Versions/3.6' (should be '/Users/myuser/.virtualenvs/my_django_environment')
ERROR: virtualenv is not compatible with this system or executable

提前致谢!

我不完全确定，但我认为运行以下命令解决了我的问题:

pip3 install --upgrade virtualenv
