我一直在尝试安装要在终端上使用的 pylint,但没有成功使用它。安装成功,但是每当我尝试运行 pylint 命令时,它都会返回以下错误 -
-bash: pylint: command not found
我尝试使用以下命令 -
pip install pylint
python -m pip install pylint
sudo pip install pylint
sudo -H pip install pylint
在尝试上述每个命令之前,我已经卸载了它,但是每次安装它时,安装都会成功,但我无法在命令行上使用它。我知道我错过了一些愚蠢的东西。
这是我在安装时得到的输出 -
My-Mac:Dev noob$ sudo -H pip install pylint

请您参考如下方法:
问题是安装的 python 可执行文件没有添加到您的路径中。我们的路径看起来并不完全相同(可能是因为不同的 python 版本,我不确定)但我的是

在我看这里之前,我看到了和你一样的问题
host:~ williamhammond$ ls /Users/williamhammond/Library/Python/3.7/bin/
dmypy epylint isort mypy pep8 pylint pyreverse stubgen symilar
一旦你把它添加到你的路径中
export PATH=$PATH:/Users/williamhammond/Library/Python/3.7/bin/
你应该能够使用pylint。要使此更改永久化,请确保将命令添加到您的
~/.bashrc
中。
