ModuleNotFound 错误但模块刚刚安装

Question

我正在使用 Windows 10，Python 3.6.4。我正在尝试使用模块 Pyperclip 并使用 pip 安装它：

c:\Users\Bertie>pip install pyperclip
Requirement already satisfired: pyperclip in c:\python36\lib\site-packages (1.8.0)

但是当我尝试运行一个使用这个模块的程序时，我得到这个错误：

c:\Users\Bertie\scraping.py test
Traceback (most recent call last):
File "C:\Users\Bertie\scraping.py", line 3, in <module>
    import webbrowser, sys, pyperclip
ModuleNotFoundError: No module named 'pyperclip'

我该如何解决这个问题？谢谢。

Answer 1

Where is the py file? Maybe try cd-ing into the folder and run python (python3) scraping.py? Also check that you have installed the correct interpreter and are using the correct version of python.

Answer 2

重新安装跟踪显示您已成功安装 python36 的软件包。检查您的系统中是否有多个 python。在 windows cmd 控制台中键入“python”，然后检查 python 版本以查看 python36 是否为默认版本。然后显式使用python解释器启动脚本“python your_python_script.py”.

Answer 3

Maybe You Installed pyperclip in conda env or a virtualenv and you forgot to activate it ?

因为这在我身上发生过很多次。

Or Maybe You Have 2 Instances Of Python installed on your computer and you accidentally installed pyperclip in the other instance of python ?
