numba 库下载总是不成功

Question

python numba 库下载总是不成功
这是为什么？
我在DOS中输入

pip3 install numba

的时候会得到一段错误 :

WARNING: You are using pip version 20.2.3; however, version 22.0.4 is available.
You should consider upgrading via the 'c:\users\pc\appdata\local\programs\python\python39\python.exe -m pip install --upgrade pip' command.

所以有人能帮帮我吗？
(如果可以的话能告诉我pyglet怎么弄吗？)

可能网络问题，使用国内镜像试下：

pip3 install numba  -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
