Python + Django：在 macOS 上設置 mkvirtualenv 時遇到問題

Question

我正在使用 macOS (10.13.3) 並安裝了 Python v 3.6.4

我正在嘗試按照這篇 Mozilla 文章的說明進行操作： 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，一路上我做了一個符號鏈接ln -s /usr/local/bin/python3 /usr/local/bin/python

---

2 python3 -V » Python 3.6.4

4 nano .bash_profile »添加以下內容： »

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

export WORKON_HOME=$HOME/.virtualenvs
# export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 # No impact
# export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3 # No impact
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python # No impact
# VIRTUALENVWRAPPER_PYTHON=`which python` # No impact
export PROJECT_HOME=$HOME/Devel
source /usr/local/bin/virtualenvwrapper.sh

5 source ~/.bash_profile

6 mkvirtualenv my_django_environment »

Running virtualenv with interpreter /usr/local/bin/python

我的 .bash_profile 文件的完整內容：

# 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

我猜我的問題與以下有關，但我不知道這意味着什么，也不知道如何解決，有人可以幫我嗎？

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

提前致謝！

Answer 1

我不完全確定，但我認為運行以下解決了我的問題：

pip3 install --upgrade virtualenv

Answer 2

很好，你設法解決了這個問題。

使用mkvirtualenv一段時間后，我建議您嘗試Pipenv如果您還沒有。

Pipenv記錄您在 virtualenv 中使用的 python 版本，而virtualenvwrapper （通過pip freeze ）沒有。
