我想导入pdfplumber并尝试
import pdfplumber
并发现错误：
---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-2-b3d6737fd8e1> in <module>
----> 1 import pdfplumber
ModuleNotFoundError: No module named 'pdfplumber'
尝试使用安装pip3 install pdfplumber并返回：

WARNING: You are using pip version 20.3.3; however, version 21.0.1 is available.
You should consider upgrading via the 'c:\python38\python.exe -m pip install --upgrade pip' command.
但是命令提示符显示我已经安装了模块？
>>> pdfplumber
<module 'pdfplumber' from 'C:\\Python38\\lib\\site-packages\\pdfplumber\\__init__.py'>
但import pdfplumber返回同样的错误。如何导入pdfplumber？
