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repro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。它第一次没用。我遇到了这个问题：python easy_install pylint Error: The system cannot find the file specified 安装终于奏效了，但是pylint没有任何改变。

安装

Pylint需要astroid包（越晚越好）。

https://github.com/PyCQA/astroid

安装应该像

一样简单

python -m pip install astroid

Pylint需要isort包（越晚越好）。

https://github.com/timothycrosley/isort

安装应该像

一样简单

python -m pip install isort

如果要从源代码发行版安装，请解压缩tarball并运行以下命令

python setup.py install

您必须以类似的方式安装依赖项。对于debian和rpm软件包，请根据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，请参见doc子目录中的用户手册。

安装这两个依赖项后，请尝试再次安装pylint。
