运行pylint返回ModuleNotFoundError:没有名为'wrapt.wrappers‘的模块

Question

我正在尝试使用带有pylint的Visual Studio代码。当我加载任何.py文件时，我在输出控制台中得到以下错误：

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

这不是特定于VS代码的，当我从命令行运行这个命令时，我得到了相同的结果：

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

安装了pylint的依赖项：

Win10 64位上的Python 3.6.3 32位。Python的路径是在系统的环境变量中设置的。

Answer 1

我在类似的环境下也遇到了同样的问题(win10 64位，VSCode，python3.6.3)。我从wrapt github repo：https://github.com/GrahamDumpleton/wrapt/tree/master/src/wrapt下载了所有文件，然后把它放到我的wrapt文件夹中。

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

现在我的林特开始工作了。

Answer 2

模块包装安装不正确，所以我将其卸载。重新安装失败，因为pip无法处理MSVC警告中的特殊字符。(不知道最初是如何报告安装成功的)。

pip处理控制台输出中的特殊字符时存在错误。作为一种解决办法，我已经替换了\lib\site-packages\pip\compat\__init__.py中的第73行

发自：

return s.decode(sys.__stdout__.encoding)

至：

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

并再次运行python -m pip install pylint。这一次它起作用了。

您可能已经使用sudo安装了pylint。尝试为用户范围进行安装，例如pip install pylint --user
