Question

当我运行mkvirtualenv TESTING时：

New python executable in TESTING/bin/python2.7
Also creating executable in TESTING/bin/python
Installing setuptools, pip, wheel...done.
virtualenvwrapper.user_scripts could not run "/Users/admin/.virtualenvs/TESTING/bin/preactivate": [Errno 2] No such file or directory

运行lsvirtualenv时出现类似错误：

bpython-dev
===========
virtualenvwrapper.user_scripts could not run
"/Users/admin/.virtualenvs/bpython-dev/bin/get_env_details": [Errno 2] No such file or directory

我已经检查了.virtualenvs / bpython-dev /（以及其他虚拟环境）以查看是否存在get_env_details，它是。

我在Mavericks上使用Time Machine执行迁移助手后发生此问题。

我正在使用Homebrew安装的Python 2。 which python会产生usr/local/bin/python，which pip会产生usr/local/bin/pip。

我的.bash_profile：

# Load /usr/local/ before /usr/bin/
export PATH=/usr/local/bin:$PATH
export PATH=$HOME/bin:$PATH


# Load the default .profile
[[ -s "$HOME/.profile" ]] && source "$HOME/.profile"


# Virtualenvwrapper
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Hacker\ School/
export PIP_VIRTUALENV_BASE=$WORKON_HOME
export PIP_RESPECT_VIRTUALENV=true
source /usr/local/bin/virtualenvwrapper.sh

Answer 1

当我发生这样的事情时，我通常会重新安装Homebrew。请参阅SO上的此链接：Safest way to reinstall Homebrew

之后，您可能需要重新创建Python Virtualenv（以获取正确的Python二进制文件和库）。

Answer 2

实际答案有点晚了，但我希望它可以帮助将来遇到同样问题的人。

实际发生了什么：

我重新安装了操作系统。
我使用Migration Assistant从Time Machine迁移数据。我相信这一步破坏了我的环境和路径。

解决方案是使用macOS Recovery并选择“从Time Machine恢复”。

virtualenvwrapper.user_scripts找不到get_env_details
