Python /usr/bin/env: bad interpreter: Not a directory
提问by lilouch
I did a mistake. I installed Python 3 and then I did the following command in order to have the defaut version Python as Python3
我犯了一个错误。我安装了 Python 3，然后我执行了以下命令，以便将默认版本 Python 作为 Python3
sudo ln -fs /opt/Python-3.4.1/python /usr/bin/python
But I wanted to come back to the python2.7 and I did
但我想回到python2.7，我做到了
sudo ln -fs /usr/bin/python2.7/python /usr/bin/python
Now, When I want to run a bash script with python inside, I have this following error:
现在，当我想运行带有 python 的 bash 脚本时，出现以下错误：
/usr/bin/env: bad interpreter: Not a directory
/usr/bin/env: 错误的解释器：不是目录
When I run this command:
当我运行此命令时：
ls -l /usr/bin/env
I have this result in red:
我的结果是红色的：
lrwxrwxrwx 1 root root 25 Jun 12 13:37 /usr/bin/env -> /usr/bin/python2.7/python
lrwxrwxrwx 1 root root 25 Jun 12 13:37 /usr/bin/env -> /usr/bin/python2.7/python
Indeed, when I go in this directory, I don't have the env executable anymore but a broken link.
事实上，当我进入这个目录时，我不再有 env 可执行文件，而是一个断开的链接。
I didn't find a solution on the internet.
我没有在互联网上找到解决方案。
Could you help me ? I begin to feel bad about my mistake.

Thanks

Okey, I solved my issue by reinstalling this env file.
好的，我通过重新安装这个 env 文件解决了我的问题。
sudo apt-get install --reinstall coreutils
Then thanks to this post in Why do people write the #!/usr/bin/env python shebang on the first line of a Python script?I know better how to switch between version and do not do the same mistake anymore.
然后感谢这篇文章为什么人们在 Python 脚本的第一行写 #!/usr/bin/env python shebang？我更清楚如何在版本之间切换并且不再犯同样的错误。
