如何修复CentOs中的“Python中的ssl模块不可用”

在GoDaddy VPS CentOs上安装新的Python 3.7.1 7.尝试pip 3安装虚拟环境或python 3 -m pip安装虚拟环境并获取：
pip配置了需要TLS/SSL的位置，但是Python中的ssl模块不可用。
openssl-devel已安装并且是最新的
这个问题已经问过很多次了，也回答过很多次了，但是我找到的解决方案并没有解决我的问题。谢谢大家！
我在下面的代码中尝试了CentOs和基于Linux的解决方案：
"SSL module in Python is not available" when installing package with pip3 #允许构建Python ssl库yum安装openssl-devel #下载 * 任何 * Python版本的源代码cd /usr/src wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tar.xz tar xf Python-3.7.1.tar.xz cd Python-3.7.1


# Configure the build w/ your installed libraries

  ./configure

  # Install into /usr/local/bin/python3.6, don't overwrite global python bin
  make altinstall

Trying to install packages with Python 3.7.2 pip causes TSL/SSL errors
"SSL module in Python is not available" when installing package with pip3
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
pip cannot confirm SSL certificate: SSL module is not available
"ssl module in Python is not available"和pip cannot confirm SSL certificate: SSL module is not available的数据类型

下面是一个适用于Python 3.7.9和CentOS 7.8.2003的工作解决方案：

su - root
yum install gcc openssl-devel bzip2-devel libffi-devel zlib-devel -y
cd /usr/src
wget https://www.python.org/ftp/python/3.7.9/Python-3.7.9.tgz
tar xzf Python-3.7.9.tgz
cd Python-3.7.9

在/usr/src/Python-3.7.9/Modules/Setup.dist中，取消注解以下4行：

SSL=/usr/local/ssl
_ssl _ssl.c \
    -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
    -L$(SSL)/lib -lssl -lcrypto

最后：

./configure --enable-optimizations
make altinstall

我在openssl版本不兼容的时候看到过这个错误，当你在一个不是最新版本的Linux系统上安装一个更新的Python（比如3.7.2）的时候，这个错误更有可能发生。
我会检查这个版本的Python需要什么版本的SSL库，如果需要，在本地安装它们。
以下是构建SSL库的基本说明：DreamHost instructions for Installing Local OpenSSL Version
您可能希望再次构建Python，并在调用./config时添加以下选项：

--with-openssl=/path/to/your/local/install

请阅读this article
基本上，你需要先安装openssl，然后在python源代码中的Modules/Setup文件中取消注解ssl相关的行，然后再进行安装。

从这篇文章的两个答案中获得灵感，下载并解压缩OpenSSL 1.1.1o，然后运行以下命令序列，我就解决了这个问题。

su - root
yum install gcc openssl-devel bzip2-devel libffi-devel zlib-devel -y
cd /usr/src
wget https://www.python.org/ftp/python/3.7.9/Python-3.7.9.tgz
tar xzf Python-3.7.9.tgz
cd Python-3.7.9
./configure --enable-optimizations --with-openssl=/path/to/your/local/install
make install
