在 Windows 上安装 Pylint 失败

Question

我尝试在 Windows 上安装 pylint（使用 Visual Studio 代码）。我有这个例外，我找不到解决方案。 我已经尝试完全重新安装 python，但我有完全相同的错误。 在其他 PC 上，相同的重现步骤可以正常工作。

你有什么问题吗？

编辑： 正如 Shankar 所说，我手动安装了 astroid。它第一次没有工作。我遇到了这个问题：python easy_install pylint Error: The system cannot find the file specified 安装终于成功了，但 pylint 没有任何改变。

这是我尝试运行 pylint 时收到的日志

安装

Pylint 需要 astroid 包（越晚越好）。

https://github.com/PyCQA/astroid

安装应该很简单

python -m pip install astroid

Pylint 需要 isort 包（越晚越好）。

https://github.com/timothycrosley/isort

安装应该很简单

python -m pip install isort

如果您想从源代码分发版安装，请解压缩 tarball 并运行以下命令

python setup.py 安装

您必须以类似的方式安装依赖项。对于 debian 和 rpm 包，请根据您的 Linux 发行版使用常用工具。

有关安装和可用分发格式的更多信息可以在 doc 子目录的用户手册中找到。

安装完这两个依赖后，再次尝试安装pylint。
