virtualenvwrapper.user_scripts 找不到 get_env_details

Question

当我运行mkvirtualenv TESTING:

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

当我运行 lsvirtualenv:

时出现类似的错误

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

我检查了 .virtualenvs/bpython-dev/（和其他虚拟环境）以查看 get_env_details 是否存在，它确实存在。

这个问题是我在Mavericks上用Time Machine执行Migration Assistant后出现的

我正在使用 Python 2 与 Homebrew 一起安装。 which python 产生 usr/local/bin/python 和 which pip 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"

Answer 1

当我遇到这样的事情时，我通常会重新安装 Homebrew。在 SO 上看到这个 link：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

现在给出实际答案有点晚了，但我希望它能帮助将来遇到同样问题的人。

实际发生了什么：

我全新安装了 OS。
我使用迁移助手从 Time Machine 迁移了我的数据。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 "Restore from Time Machine"。
