树莓派Raspberry Pi系统编译安装Python3.7

一、更新树莓派系统

sudo apt-get update
sudo apt-get upgrade

二、安装python需要的依赖

sudo apt-get install build-essential libsqlite3-dev sqlite3 bzip2 libbz2-dev

sudo apt-get install libffi-dev

三、下载Python的源代码并解压

cd /usr/local/src
wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz
tar zxvf Python-3.7.4.tgz

四、配置、编译、安装

sudo mkdir /usr/local/python
sudo ./configure --prefix=/usr/local/python
sudo make
sudo make install

报错

ModuleNotFoundError: No module named '_ctypes'

  sudo apt-get update

sudo apt-get install libffi-dev

五、创建符号链接

sudo ln -s /usr/local/python/bin/python3 /usr/bin/python
sudo ln -s /usr/local/python/bin/python3 /usr/bin/python3
sudo ln -s /usr/local/python/bin/pip3 /usr/bin/pip
sudo ln -s /usr/local/python/bin/pip3 /usr/bin/pip3

如果提示已经存在

rm /usr/bin/python
rm /usr/bin/python3
rm /usr/bin/pip
rm /usr/bin/pip3

 

 

问题1 报错pip

1安装更新修复

 wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate

 sudo python get-pip.py

2测试

1. 运行python3 -m pip --version以查看是否安装了 pip。
2. 如果是，运行python3 -m pip install --upgrade pip。
3. 如果没有，运行sudo apt-get install python3-pip，然后再做一次。

3 还是不行修改

#!/usr/local/python/bin/python3.7
# -*- coding: utf-8 -*-
import re
import sys

#from pip._internal import main
from pip import main
if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

　　修改

#from pip._internal import main
from pip import main

　　

 问题2 thonny软件无法使用

导致树莓派自带的thonny无法正常用，卸载重装

sudo apt autoremove thonny

　　安装

sudo apt install thonny
