Question

我正在迈入Python的第一步，其中一部分就是将其全部安装并在MacBook Pro上运行。我一直在努力安装pylint，因为Visual Studio Code不断通知我。

虽然我无法告诉您原因，但我了解到操作皮棉机是有益的，但我决心从一开始就做好准备。在编码方面，我是一个菜鸟。请保持友善。

我在github上找到了此链接，尽管响应超出了我本人：https://github.com/pypa/pip/issues/5465

侧面问题-pip和pip3之间有区别吗？我的bin文件夹中似乎都有它们。谢谢：）

我尝试过的事情

我安装了python 2.7（使用mac进行系统安装）和python 3.7（同种安装）。我已经更新了pip（为此我必须使用'pip3 install --update pip'）

我尝试过：点安装pylint pip3安装pylint sudo pip安装pylint

当我尝试sudo时（不建议以后阅读），我还会收到以下警告：

WARNING: The directory '/Users/maxwartelle/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
WARNING: The directory '/Users/maxwartelle/Library/Caches/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

这是安装的完整输出。我认为它正在使用缓存文件，就像我尝试过几次一样，这是第一次下载它们。

Answer 1

解决方案是运行“ Install Certificates.command” shell命令。

可在Applications \ Python 3.7 \

中找到

就像我说的，完全是菜鸟。
