ModuleNotFoundError: 没有名为“win32api"的模块 [英] ModuleNotFoundError: No module named 'win32api'

问题描述

这是收到的错误:

    Traceback (most recent call last):
  File "C:/Users/Joe Martin/AppData/Local/Programs/Python/Python37/test.py", line 12, in <module>
    import win32com.client
  File "C:\Users\Joe Martin\AppData\Local\Programs\Python\Python37\lib\site-packages\win32com\__init__.py", line 5, in <module>
    import win32api, sys, os
ModuleNotFoundError: No module named 'win32api'

尝试导入 win32com.client 模块时出现此错误.

This error occurs when trying to import the win32com.client module.

尝试的解决方案:

• 全新擦除并安装 Python 3.7
• pip install pypiwin32
• pip install pywin32
• 运行 pywin32_postinstall.py

我找不到任何其他解决方案来解决此问题.

I cannot find any other solution for how to fix this issue.

推荐答案

这通常是因为安装包后没有附加 PythonPath.检查文件夹下的文件--pywin32.pth--\\PythonVersion\\Lib\\site-packages\\.

This is usually because no PythonPath is appended after the package is installed. Check the file--pywin32.pth under the folder--\\PythonVersion\\Lib\\site-packages\\.

文件内容如下:

# .pth file for the PyWin32 extensions
win32
win32\lib
Pythonwin
# Entries needed for a "portable" installations, where the post_install script
# isn't run, which would normally copy the pywin32 core DLL files to either
# the top of the python directory.
# We just stick the source of these DLLs directly on the PATH.
import os;os.environ["PATH"]+=(';'+os.path.join(sitedir,"pywin32_system32"))

或者创建一个PYTHONPATH环境变量，并将win32和win32/lib路径加入其中.

Or create a PYTHONPATH environment variables, and append the win32 and win32/lib path into it.

你也可以临时在项目中加入这两条Python路径:

You could also add these two paths to Python in project temporarily：

import sys
sys.path.append('\\PythonVersion\\lib\\site-packages\\win32')
sys.path.append('\\PythonVersion\\lib\\site-packages\\win32\\lib')

添加路径暂时有效.
