在装有 Python 3.9.5 和 pipenv 2021.5.29 的 Windows 10 机器上。在一个pipenv shell：

我用过pipenv install。这将返回：

然而，当我尝试调用为其创建环境的脚本时，我得到：

(imseg-cT2t34Fc) C:\Users\jp\Documents\programming\imseg\src>python3 model.py
Traceback (most recent call last):
  File "C:\Users\jp\Documents\programming\imseg\src\model.py", line 14, in <module>
    import matplotlib.pyplot as plt
ModuleNotFoundError: No module named 'matplotlib'

我阅读并尝试过

pip install pipx
pipx install pipenv

问题没有改变。我的 pipenv 环境有什么问题？

编辑： where python3返回：

C:\OSGeo4W\bin\python3.exe
C:\OSGeo4W\apps\Python39\python3.exe
C:\Users\jp\AppData\Local\Microsoft\WindowsApps\python3.exe

编辑（＃2）：我不清楚python可执行文件应该存在哪里？我想我没有得到虚拟环境的东西。如果python可执行文件应该存在于虚拟环境中，为什么python可执行文件没有安装在虚拟环境中。开始？pipenv 网站只是说有 python 并且我安装了 as pip3 install --user pipenv，所以它看起来应该可以工作。我仍然想知道如何解决这个问题。

答案很简单。调用 Python 可执行文件的行应该是

pipenv run python model.py

代替

python model.py

正如这个问题的公认答案所指出的那样。
