-bash: pylint: 命令未找到

Question

我一直在尝试安装pylint以在终端上使用，但是一直无法成功使用它。安装成功，但每当我尝试运行pylint命令时，它都会返回以下错误-

我一直在努力安装pylint以在终端上使用，但是尝试不成功。安装成功后，每当我尝试运行pylint命令时，就会返回以下错误-

-bash: pylint: command not found

我已经尝试使用以下命令 -

pip install pylint
python -m pip install pylint
sudo pip install pylint
sudo -H pip install pylint

在尝试以上各个命令之前，我已经卸载了它，但每次重新安装时，安装都会成功，但我无法在命令行中使用它。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 -

问题是安装的Python可执行文件未被添加到您的路径中。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），但我的路径是：

host:~ williamhammond$ pip install pylint
Requirement already satisfied: pylint in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (2.3.1)
Requirement already satisfied: astroid<3,>=2.2.0 in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (from pylint) (2.2.5)
Requirement already satisfied: isort<5,>=4.2.5 in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (from pylint) (4.3.21)
Requirement already satisfied: mccabe<0.7,>=0.6 in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (from pylint) (0.6.1)
Requirement already satisfied: wrapt in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (from astroid<3,>=2.2.0->pylint) (1.11.2)
Requirement already satisfied: six in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (from astroid<3,>=2.2.0->pylint) (1.12.0)
Requirement already satisfied: typed-ast>=1.3.0; implementation_name == "cpython" in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (from astroid<3,>=2.2.0->pylint) (1.4.0)
Requirement already satisfied: lazy-object-proxy in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (from astroid<3,>=2.2.0->pylint) (1.4.1)

在我查看这里之前，我遇到了与你相同的问题。

host:~ williamhammond$ ls /Users/williamhammond/Library/Python/3.7/bin/
dmypy           epylint         isort           mypy            pep8            pylint          pyreverse       stubgen         symilar

一旦将此添加到您的路径中，如下：

export PATH=$PATH:/Users/williamhammond/Library/Python/3.7/bin/

您应该能够使用pylint。要使此更改永久，请确保将命令添加到您的~/.bashrc中。

在William Hammond的回复中，最后一个评论（使此更改永久）中，请确保将命令添加到您的~/.bashrc中，您会发现上面的超链接是完成此操作的有用指南。

Answer 3

我只是复制了文件路径，然后将其输入到文件中，直接带我到脚本存储的位置，然后我复制了所有的脚本，并将它们添加到与我想要运行的代码相同的文件夹中。

总结：我移动了下载路径上的文件。
