Visual Studio 代码：OSError：[Errno 30] 尝试在 Linux Mint 上安装 pylint 时出现只读文件系统

Question

我全新安装了 Linux Mint 18.3。之后，安装 Visual Studio Code 和 Python 扩展，将 python3 设置为解释器。当打开带有 .py 文件扩展名的文件时，VSC 建议安装 pylint。选择“安装”后，我在集成终端中得到以下信息：

You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

我尝试将 /usr/lib/python3.5/ 及其子目录的所有者更改为我，但这没有帮助。

我该如何解决？非常感谢。

您最好的选择是创建虚拟环境或使用用户安装。

对于虚拟环境，如果您在 VS Code 中打开的目录中创建它，那么扩展程序将默认选择并使用它。然后，您可以将 Pylint 安装到虚拟环境中。

或者，您可以使用/usr/bin/python3 install --user --upgrade pylint 全局安装 Pylint。这会将其安装到您的用户目录中，以获取python3 所在的 Python 版本。 （这将成为2018.1 版本中的默认功能。）
