take Linux shell Change it to bash

see shell Is it bash, Run the following command at the terminal

ls -l /bin/sh

If yes, it displays /bin/sh -> bash It's normal , Otherwise, please modify it in the following way ：

Method 1 ： Run the following command at the terminal , And then choose no.

sudo dpkg-reconfigure dash

Method 2 ： Delete first sh, Then create soft links .

rm -rf /bin/sh
sudo ln -s /bin/bash /bin/sh

install Python Environmental Science

1. open Linux Compile the server terminal .

2. Enter the command “python3 --version”, see Python Version number . Need to use python3.7 Above version , Otherwise, please follow the following steps , With python3.8 For example ：

   • If Ubuntu Version is 18, function "sudo apt-get install python3.8"

   • If Ubuntu Version is 16, Please install by downloading the package python:

     1. python Installation environment depends on (gcc, g++, make, zlib, libffi) Please run ：

     "sudo apt-get install gcc && sudo apt-get install g++ && sudo apt-get install make && sudo apt-get install zlib* && sudo apt-get install libffi-dev "

     1. obtain python3.8.5 Installation package , Put it in linux Server , function ：

     “tar -xvzf Python-3.8.5.tgz && cd Python-3.8.5 && sudo ./configure && make && sudo make install”

3. determine Python-3.8.5 After installed , function "which python3.8", Link the echo path to "/usr/bin/python", Example ：

    "cd /usr/bin && sudo rm python && sudo ln -s /usr/bin/python3.8 python && python --version"
   
     If the system exists python3, adopt "python3 --version" Instruction query version , If it is not 3.7 Above version , You also need to execute the following instructions 
   
    "cd /usr/bin && sudo rm python3 && sudo ln -s /usr/bin/python3.8 python3 && python3 --version"
   

4. install Python Package management tools , function “sudo apt-get install python3-setuptools python3-pip -y” command .（ Need to be root/sudo Permission installation ）, upgrade pip3 function "sudo pip3 install --upgrade pip".

     Or install it according to the official website Python Package management tools ： download "curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py" after , Re execution "python get-pip.py"
   

5. install python modular setuptools, function "pip3 install setuptools"
