未找到模块 pip

Question

出于某种原因，找不到我的 pttsx3 模块，我在有和没有虚拟环境的情况下都安装了它，它甚至显示我在 pip 中安装了它，通过 pip 列表安装

Answer 1

您说您没有使用虚拟环境，但是您的 pip 似乎属于 python 在

e:\programs i wrote heh\my ai\bin\env\scripts\python.exe

而您用来运行脚本（具有导入行）的 python 是

C:\Users\mmmke\AppData\Local\Programs\Python\Python39\python.exe

所以要么使用e:\programs i wrote heh\my ai\bin\env\scripts\python.exe来运行你的脚本，要么安装正确的 python：

C:\Users\mmmke\AppData\Local\Programs\Python\Python39\python.exe -m pip install ...
