Local version: python3.8
Problem: Error reporting when installing third-party libraries
Step 1: Install the third-party library in the setting of pycharm and report an error: Try to run this command from the system terminal. Make sure that you use the correct version of 'pip' installed for your Python interpreter located at 'D:\software\python3 .8\python.exe'.
As shown below:
Step 2: Using the command pip install openpyxl in the Terminal of pycharm also reports an error: WARNING: You are using pip version 19.2.3, however version 22.2.2 is available. You should consider upgrading via the 'python -m pip install -- upgrade pip' command.
Then, I made countless attempts based on the information on the Internet. The following is my bumpy life:
because of the problem of the pip version, I said to upgrade the pip version first, so I tried crazily. After countless failures, the upgrade was successful unexpectedly.
Attempt 1: According to the prompt on pycharm, directly execute python -m pip install --upgrade pip
The result failed, and the same error was reported, as follows:
Attempt 2: Enter easy_install -U pip on the cmd command line
Failed, no response directly

Attempt 3: timed out, failed
Enter python -m pip install --upgrade pip reference document link in the cmd command line

Attempt 4: Hmm, great, failed with timeout again
Enter python -m pip install -U --force-reinstall pip reference document link in the cmd command line

Attempt 5: Change the mirror, such as Tsinghua mirror to obtain the library

Well, it was others who successfully solved the problem, and I failed again.
Attempt 6: Double-click the installed 19.2.3 version of pip in the setting, and see the latest 22.2.2 version in the pop-up window, install
Result: It was a direct success. At this time, I can't speak in my heart. Going around in a big circle, it was solved so easily? Doubt what you are doing in front of you.
Summary: As long as you don't give up, the problem will definitely be solved in the end. Try the solutions on the Internet more, just in case it succeeds. There is also the simplest one, we have to try it. We often ignore the path in front of us and choose to take a detour.
Did you think it was over? Well, that's what I thought too, I finally successfully upgraded pip. However, when I went back to the setting to reinstall the three-party library, I still reported an error and returned to the origin of the problem. . .
Then, with the mentality of being a dead horse as a living horse doctor, I entered cmd and executed the installation command: pip install selenium
was successful. . .
This is a trance afternoon, I don't know if I am a rookie, will I install it in cmd in the future?
I need to take it easy and study it later. . . .
