get-pip.py

This is a Python script that uses some bootstrapping logic to install pip.

• Download the script, from https://bootstrap.pypa.io/get-pip.py.

• Open a terminal/command prompt, cd to the folder containing the get-pip.py file and run

• python3 get-pip.py

The above method will install pip to /usr/local/bin/pip, and then add a soft link to use it. The problematic version is 22.02, just upgrade to 23

 

ln -s /usr/local/bin/pip /usr/bin/pip3

Because few people use ubuntu22.04 in termux, this problem is reported wrong and there is no related solution

And because the numpy package in python is required, this pip must be installed, so a more unconventional method is used

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

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

Download the zip version of pip, and then this can be used normally without error reporting, check the help through the following command

python pip.pyz --help

 So you can install Numpy with the following command

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

 Alibaba Cloud  http://mirrors.aliyun.com/pypi/simple/ 
 University of Science and Technology of China  https://pypi.mirrors.ustc.edu.cn/simple/ 
 Douban  http://pypi.douban.com/simple / 
 Tsinghua University  https://pypi.tuna.tsinghua.edu.cn/simple/ 
 University of Science and Technology of China  http://pypi.mirrors.ustc.edu.cn/simple/

You can add the -i parameter to the back when using pip to specify the pip source 
 

It works fine after that

Another way is to directly install the compiled package, which seems to be more convenient, the previous one is written for nothing:(

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