Pi 3B+编译安装python3.6.8

树莓派镜像版本2018-11-13，更新到2019-01-09

sudo apt-get update
sudo apt-get upgrade

sudo apt-get install build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev

wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tar.xz
tar xf Python-3.6..tar.xz

cd Python-3.6.
./configure --with-ssl
make
sudo make install

如果参数--with-ssl无效使用进行下面操作后重新编译，据说3.6.5的--with-ssl参数无效

sudo nano Python-3.6./Modules/Setup

Ctrl+W找到下面的内容，已删除第2、7、8、9行前面#注释

 # Socket module helper for socket()
 _socket socketmodule.c

 # Socket module helper for SSL support; you must comment out the other
 # socket line above, and possibly edit the SSL variable:
 #SSL=/usr/local/ssl
 _ssl _ssl.c \
        -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
        -L$(SSL)/lib -lssl -lcrypto

Ctrl+O保存，重新编译安装

cd Python-3.6.
make
sudo make install

检查SSL模块

pi@raspberrypi:~ $ python3
Python 3.6. (default, Jan   , ::)
[GCC 6.3. ] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import ssl
>>>

不建议执行以下操作，会删除HA需要的部分依赖

sudo rm -r Python-3.6.
rm Python-3.6..tar.xz
sudo apt-get --purge remove build-essential tk-dev
sudo apt-get --purge remove libncurses5-dev libncursesw5-dev libreadline6-dev
sudo apt-get --purge remove libdb5.-dev libgdbm-dev libsqlite3-dev libssl-dev
sudo apt-get --purge remove libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev
sudo apt-get autoremove
sudo apt-get clean
