在termux中安了 ubuntu22.04 ，在其中中使用apt install python3-pip 后运行pip3出错

因为很少有人在termux中使用ubuntu22.04 ，这个问题报错了也没有相关解决方法

又因为需要python 中的numpy包，必须要安装这个pip，于是使用了一个比较非常规的方法

Installation - pip documentation v23.0https://pip.pypa.io/en/stable/installation/

wget https://bootstrap.pypa.io/pip/pip.pyz

下载了pip的zip版本，然后这个可以正常使用不报错，通过下面指令查看帮助

python pip.pyz --help

 于是通过下面的指令就可以安装Numpy了

python3 pip.pyz install numpy -i https://pypi.mirrors.ustc.edu.cn/simple/

 阿里云 http://mirrors.aliyun.com/pypi/simple/ 
 中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/ 
 豆瓣(douban) http://pypi.douban.com/simple/ 
 清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/ 
 中国科学技术大学 http://pypi.mirrors.ustc.edu.cn/simple/

可以在使用pip的时候在后面加上-i参数，指定pip源 
 

之后就好用了

另外还有一种方法就是直接安装已经编译好的包，这样好像更方便，前面的白写了:(

apt-get install python3-numpy python3-scipy python3-matplotlib
