Linux安装Python3打开SSL及配置VSCode

一、Python3.7.3源码下载

https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tar.xz

二、解压

tar -xvf  Python-3.7.3.tar.xz -C ./ 

三、开启SSL模块：
打开Python3.7.3/Modules/Setup.dist

_socket socketmodule.c    #该行取消注释

# 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            #该行取消注释
_ssl _ssl.c \                      #该行取消注释
    -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \        #该行取消注释
    -L$(SSL)/lib -lssl -lcrypto        #该行取消注释

四、编译安装Python
库：
CentOS:

yum install -y openssl-devel libffi-devel zlib zlib-devel gcc make

Ubuntu:

apt install libssl-dev libffi-dev zlib1g-dev gcc make

./configure --prefix=/usr/local/python3.7.3 --enable-optimizations #a release build with all stable optimizations active
#./configure --with-ssl-default-suites --prefix=/usr/local/python3
make
make install

五、链接

ln -s /usr/local/python3.7.3/bin/python3.7 /usr/bin/python373
#ln -s /usr/local/python3.7.3/bin/pip3.7 /usr/bin/pip373
检查版本
python373 --version
python373 -m pip -V

六、VSCode安装pylint

python373 -m pip install pylint --user
#python373 -m pip install pylint -i http://pypi.douban.com/simple --trusted-host pypi.douban.com --user
更新pip
python373 -m pip install --upgrade pip --user
#python373 -m pip install --upgrade pip -i http://pypi.douban.com/simple --trusted-host pypi.douban.com --user

加入/root/.local/bin到PATH

vim /etc/profile
PATH=$PATH:/root/.local/bin
export PATH

七、其他错误

subprocess.CalledProcessError: Command '('lsb_release', '-a')' returned non-zero exit status 1.

cp /usr/lib/python3/dist-packages/lsb_release.py /usr/local/python373/lib/python3.7/

Fedora升级python3.7.4后dnf出错的问题
ln -s /usr/bin/python3.7 /usr/bin/python3
3.7.4没有python3-dnf包

Ubuntu升级Python3.7.4后apt出错的问题
ln -s /usr/bin/python3.7 /usr/bin/python3
不能ln 到新安装的/usr/local/python3/bin/python3.7
