以前“請求”庫正在工作，但我想做一個項目并安裝一些庫，并且“request==2.22.0”包含在庫中。安裝庫后，我發現我在PyCharm上收到一個錯誤：Traceback (most recent call last):  File "C:/Users/User/Desktop/python/projects/youtube downloader.py", line 5, in <module>    import requestsModuleNotFoundError: No module named 'requests'當我嘗試使用pip再次安裝請求時，我不斷收到這些錯誤，我也嘗試卸載請求，然后重新安裝：C:\Users\User>pip3 install requestsRequirement 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)Requirement already satisfied: idna<2.9,>=2.5 in c:\users\User\appdata\roaming\python\python37\site-packages (from requests) (2.8)Requirement already satisfied: urllib3<1.25,>=1.21.1 in c:\users\User\appdata\roaming\python\python37\site-packages (from requests) (1.24.1)Requirement already satisfied: certifi>=2017.4.17 in c:\users\User\appdata\roaming\python\python37\site-packages (from requests) (2018.11.29)C:\Users\User>pip install requestsRequirement already satisfied: requests in c:\users\muffin\anaconda3\lib\site-packages (2.21.0)Requirement already satisfied: idna<2.9,>=2.5 in c:\users\User\appdata\roaming\python\python37\site-packages (from requests) (2.8)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)Requirement already satisfied: urllib3<1.25,>=1.21.1 in c:\users\User\appdata\roaming\python\python37\site-packages (from requests) (1.24.1)Requirement already satisfied: certifi>=2017.4.17 in c:\users\User\appdata\roaming\python\python37\site-packages (from requests) (2018.11.29)我注意到我有兩個？我的電腦里有蟒蛇，但我從來沒有知道我應該用兩條蟒蛇做什么（我用Ananconda來表示木星筆記本和PyCharm），我假設這可能是為什么pip不能像我預期的那樣工作的問題......還是不行。我很困惑。++所以我在木星筆記本上發現，我可以毫無問題地導入請求庫，所以我認為我需要在另一條路徑上下載庫???..任何人都可以幫忙嗎？提前非常感謝你。
