在Visual Studio 2017中运行pylint不起作用

Question

我在我的虚拟环境中安装了pylint，并在解决方案中配置并激活了虚拟环境。

当我通过命令提示符运行pylint时（激活虚拟环境之后），它可以工作：

C:\Users\AmosH\Documents\Workspace\local_gallery>pylint projects
Using config file C:\Users\AmosH\Documents\Workspace\local_gallery\.pylintrc
************* Module projects.admin
C:  1, 0: Missing module docstring (missing-docstring)
************* Module projects.apps
C:  1, 0: Missing module docstring (missing-docstring)
C:  4, 0: Missing class docstring (missing-docstring)
************* Module projects.models
C:  1, 0: Missing module docstring (missing-docstring)
C:  5, 0: Missing class docstring (missing-docstring)
C: 15, 4: Missing method docstring (missing-docstring)
...

但是当我在Visual Studio中运行它时（右键单击项目＆gt; Python＆gt;运行PyLint）它只会显示奇怪的警告：

每个文件都无法加载自身，或类似的东西（请注意，每个模块都不会尝试加载其他模块，但本身并且失败）。

当我双击任何警告时，我可能会收到如下错误：

如果您没有选择.pyproj文件的位置作为项目的根目录，Visual Studio 2017中存在导致此问题的错误。在我的情况下，我选择了父目录，并且Visual Studio 2017没有对pylint在这些情况下工作所需的适当调整。每当我通过Visual Studio 2017运行pylint时，它都会在父目录中搜索模块，即使我可以使用Visual Studio 2017浏览我的项目并完全编辑文件。这确实很奇怪。
