You are using pip version 9.0.3, however version 20.2.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

嘗試了很多辦法，比如網(wǎng)上說的：pip install -U setuptools 也沒有用
后來嘗試著自己看了報(bào)錯憾筏，發(fā)現(xiàn)有一行報(bào)錯是：
ERROR: 'pip wheel' requires the 'wheel' package. To fix this, run: pip install wheel
就想著可能是wheel的問題嚎杨，于是執(zhí)行了pip install wheel
下載成功之后再執(zhí)行一次pip install pylint
成功了，以下是執(zhí)行過程：

$ pip3 install wheel
