python - 模块未找到错误: No module named 'requests' even after pip installed requests in Pycharm

Question

以前“requests”库可以工作，但我想做一个项目并安装一些库，并且“requests==2.22.0”包含在库中。安装库后，我发现 PyCharm 出现错误:

Traceback (most recent call last):
  File "C:/Users/User/Desktop/python/projects/youtube downloader.py", line 5, in <module>
    import requests
ModuleNotFoundError: No module named 'requests'

当我尝试使用 pip 再次安装 requests 时，我不断收到这些错误， 我还尝试卸载请求然后重新安装:

C:\Users\User>pip3 install requests
Requirement already satisfied: requests in c:\users\muffin\anaconda3\lib\site-packages (2.21.0)
Requirement already satisfied: chardet<3.1.0,>=3.0.2 in c:\users\User\appdata\roaming\python\python37\site-packages (from requests) (3.0.4)

我注意到我有两个？ python 在我的计算机中，但我从来不知道我应该用两个 python 做什么(我使用 Ananconda 作为 Jupiter 笔记本和 PyCharm)，我假设这可能是为什么 pip 没有按我的预期工作的问题。 。 或不。我很困惑。

++ 所以我发现在 Jupiter Notebook 中，我可以毫无问题地导入 requests 库，所以我想我需要在其他路径中下载该库???..

有人可以帮忙吗？ 提前非常感谢您。

您尚未为 PyCharm 配置 Python 解释器。关注 this tutorial你应该没问题。我建议使用 Anaconda 并创建一个 virtual environment ，手动或在 PyCharm 中。将 requests 安装到该环境。
