在 VSCode 上安装 Pylint 时权限被拒绝

Question

When trying to enable linting with Pylint, and format on save with autopep8, neither will install because of a permission denied error.

Pylint:

IOError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/mccabe.py'

Autopep8:

IOError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/pep8.py'

Answer 1

You can press ⬆ (up arrow key) in the terminal tab after the install fails to return to the command that it ran. In this case:

/usr/bin/python -m pip install pylint

Press fn+⬅ (left arrow key) to jump to the beginning of the line, then insert a 'sudo ' (no quotes, but including the trailing space) in front of the command, and press enter to re-run the command as root -- it should look like this:

sudo /usr/bin/python -m pip install pylint

You will be prompted for your password then the package will be installed without permissions errors.

Answer 2

运行此命令：

sudo chown -R $USER /Library/Python/2.7

Answer 3

Use for Python V3+

sudo -H python -m pip install pylint

then simply check the version via

pylint --version 

should output something like

pylint 2.6.2
astroid 2.4.2
Python 3.9.1 (default, Feb  1 2021, 12:12:57) 
[Clang 12.0.0 (clang-1200.0.32.29)]
