运行pylint出现ModuleNotFoundError: No module named 'wrapt.wrappers'错误

Question

我正在尝试使用Visual Studio Code和pylint。当我加载任何.py文件时，输出控制台会显示以下错误：

Linting with pylint failed.
You could either install the 'pylint' linter or turn it off in setings.json via "python.linting.pylintEnabled = false".
Error: Command failed: C:\Users\(...)\AppData\Local\Programs\Python\Python36-32\python.exe -m pylint --msg-template='{line},{column},{category},{msg_id}:{msg}' --reports=n --output-format=text c:\Users\(...)\Desktop\Untitled-1.py

这不仅适用于VS Code，当我从命令行运行此命令时，结果也相同：

C:\Users\(...)\AppData\Local\Programs\Python\Python36-32\python.exe -m pylint --msg-template='{line},{column},{category},{msg_id}:{msg}' --reports=n --output-format=text c:\Users\(...)\Desktop\Untitled-1.py

已安装pylint所依赖的软件包：

在Win 10 64位系统上，Python 3.6.3的32位版本已经安装。Python的路径已经设置在系统环境变量中。

Answer 1

我遇到了同样的问题，环境类似（win 10 64位，VSCode，Python 3.6.3）。 我从wrapt github仓库下载了所有文件： https://github.com/GrahamDumpleton/wrapt/tree/master/src/wrapt 然后我把它放在我的wrapt文件夹中。

    C:\Users\(...)\AppData\Local\Programs\Python\Python36-32\lib\site-packages\wrapt\

现在我的代码检查器正在工作。

linter是否被视为通过pip安装？ - Cutter

是的。我实际上在另一个环境（win7，32位）中使用vscode，包括python linter，并且与win10 64位中的linter不同，它在pip安装后就可以正常运行。当我比较那里的linter和我从上面的github获取的linter时，据我所知，它们的行为是相同的。 - Leonard AB

请告诉我上面的 Github 存储库是否也适用于您。 - Leonard AB

Answer 2

你可能已经使用sudo安装了pylint。尝试以用户范围安装，例如pip install pylint --user

Answer 3

模块wrapt安装不正确，因此我卸载了它。重新安装失败，因为pip无法处理MSVC警告中的特殊字符。（不知道第一次安装如何报告成功）。

pip在控制台输出中处理特殊字符存在错误。作为解决方法，我替换了\lib\site-packages\pip\compat\__init__.py中第73行：

从：

return s.decode(sys.__stdout__.encoding)

到：

return s.decode(sys.__stdout__.encoding, "replace")

然后再次运行python -m pip install pylint。这次成功了。
