python - VIRTUALENV bash :/usr/local/bin/virtualenv:/usr/bin/python: bad interpreter: No such file or directory

Question

我已经尽力了，但现在我需要帮助!我已经达到了我所能理解的极限。

我的错误:

andytmac:~ admin$ lsvirtualenv
andytmac:~ admin$ mkvirtualenv test
-bash: /usr/local/bin/virtualenv: /usr/bin/python: bad interpreter: No such file or directory

我的看法是 virtualenv 不知道 python 在哪里。是这样吗？我怎样才能解决这个问题？

系统是Mac OSX 10.9.4

我已经使用brew安装了python 2.7.8.1。 - Python 2.7*东西*在那里，但我删除了它。然而，我记不清我到底做了什么。对不起。我是 Mac 新手。 - 这个新的 python 实例位于:/usr/local/Cellar/python/2.7.8_1/ - 当我读取/usr/local/bin/python 时，/usr/local/bin/python 文件指向上面的内容

.bash_配置文件:

export PROJECT_HOME=$HOME/Projects
export PATH=$PATH:/usr/local/bin
export PATH=$PATH:/usr/local/bin/psql
export PYTHONPATH=$PYTHONPATH:/usr/local/bin/python

export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh

alias showhidden='defaults write com.apple.finder AppleShowAllFiles TRUE; killall Finder'
alias hidehidden='defaults write com.apple.finder AppleShowAllFiles FALSE; killall Finder'

路径:

andytmac:~ admin$ cat /etc/paths
/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin

Python 似乎可以工作，但路径看起来很繁忙

感谢任何帮助!

事情进展得很糟糕......救命!尤其是因为我弄乱了链接，我认为这些链接有问题

andytmac:~ admin$ ln -s /usr/bin/python /System/Library/Frameworks/Python.framework/Versions/2.7

我以为我已经拥有了。我更改了链接如下。但还是搞砸了。

Andytmac:~ admin$ readlink /System/Library/Frameworks/Python.framework/Versions/Current
/System/Library/Frameworks/Python.framework/Versions/2.7
Andytmac:~ admin$ readlink /System/Library/Frameworks/Python.framework/Versions/2.7
/usr/bin/python
Andytmac:~ admin$ readlink /usr/bin/python
/usr/local/Cellar/python/2.7.8_1
Andytmac:~ admin$ virtualenv ENV
-bash: /usr/local/bin/virtualenv: /usr/bin/python: bad interpreter: Permission denied
Andytmac:~ admin$

我最好现在就停下来，以免造成更多伤害。

我将/usr/bin/python 更改为指向/usr/local/Cellar/python/2.7.8_1/bin python2.7:

Andytmac:~ admin$ readlink /usr/bin/python
/usr/local/Cellar/python/2.7.8_1/bin/python2.7

否，错误已演变为以下内容:

Andytmac:~ admin$ lsvirtualenv
Andytmac:~ admin$ mkvirtualenv Test

解决如下:

1. 通过下载并重新安装 Maverics(使用自动 Apple 启动工具)来恢复系统
2. 遵循此处的建议: Can't pip install virtualenv in OS X 10.8 with brewed python 2.7和这里: http://www.lowindata.com/2013/installing-scientific-python-on-mac-os-x/
3. 我的 virtualenv 与第 (2) 页中指定的位置不同，因此 bash_profile 应包含源/usr/local/bin/virtualenvwrapper.sh代替:源/usr/local/share/python/virtualenvwrapper.sh
