python - 无法使用 sudo python 但我可以在没有 sudo 的情况下使用 python

Question

我正在对我的 linux 机器(通过 ssh 的 rhel)进行一些维护，但是当我这样运行 python 脚本时:

asemani$ python3.6 get-pip.py

  File "get-pip.py", line 20061, in <module>
    main()
  File "get-pip.py", line 194, in main
    bootstrap(tmpdir=tmpdir)
  File "get-pip.py", line 82, in bootstrap
    import pip
  File "<frozen importlib._bootstrap>", line 961, in _find_and_load
  File "<frozen importlib._bootstrap>", line 950, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 646, in _load_unlocked
  File "<frozen importlib._bootstrap>", line 616, in _load_backward_compatible
  File "/tmp/tmp04ft8p5f/pip.zip/pip/__init__.py", line 26, in <module>

PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.6/site-packages/setuptools-28.8.0.dist-info'

当我尝试使用 sudo 时:

asemani$ sudo python3.6 get-pip.py'
[sudo] password for asemani: 
sudo: python3.6: command not found

无法识别 Python？到底是怎么回事？如何在 python3.6 上使用 sudo。我很确定我安装正确。

编辑:

方法一:

[asemani@746c9prda5r asemani]$ sudo -E python3.6 get-pip.py
sudo: python3.6: command not found

方法 2:

[asemani@746c9prda5r asemani]$ sudo /usr/local/bin/python3.6 get-pip.py 
[sudo] password for asemani:

看起来 sudo 正在从环境中丢失您的 PATH，您需要将完整路径传递给 python3.6:

which python3.6

这将为您提供完整路径，例如/opt/bin/python3.6

然后你需要做

sudo /opt/bin/python3.6 get-pip.py
