错误一
安装过程中遇到：
ERROR: Command errored out with exit status 1: /home/welkin/Desktop/AFL/epf/.env/bin/python3 -u -c ‘import sys, setuptools, tokenize; sys.argv[0] = ‘"’"’/tmp/pip-install-rwvrrmy9/matplotlib/setup.py’"’"’; file=’"’"’/tmp/pip-install-rwvrrmy9/matplotlib/setup.py’"’"’;f=getattr(tokenize, ‘"’"‘open’"’"’, open)(file);code=f.read().replace(’"’"’\r\n’"’"’, ‘"’"’\n’"’"’);f.close();exec(compile(code, file, ‘"’"‘exec’"’"’))’ install --record /tmp/pip-record-q37ze_jx/install-record.txt --single-version-externally-managed --compile --install-headers /home/welkin/Desktop/AFL/epf/.env/include/site/python3.9/matplotlib Check the logs for full command output.
WARNING: You are using pip version 20.1.1; however, version 22.0.3 is available.
You should consider upgrading via the ‘/home/Desktop/AFL/epf/.env/bin/python3 -m pip install --upgrade pip’ command.
这里只需要按照它的指示更新pip即可
输入：python3 -m pip install --upgrade pip' command
然后就会报第二个错误

note: This error originates from a subprocess, and is likely not a problem with pip.
error: legacy-install-failure
我的主机解决办法是：
sudo apt-get install libfreetype6-dev
sudo apt-get install pkg-config
sudo apt-get install libpng12-dev
sudo apt-get install pkg-config
