python - 如何在 CentOs 中修复 "ssl module in Python is not available"

Question

在 GoDaddy VPS CentOs 7 上安装新的 Python 3.7.1。尝试 pip3 install virtualenv 或 python 3 -m pip install virtualenv 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。

已安装 openssl-devel 并且是最新的

这个问题已被问及多次回答，但我找到的解决方案并没有解决我的问题。谢谢大家!

我尝试了以下基于 CentOs 和 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 cd/usr/源文件 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

这是一个适用于 Python 3.7.9 和 CentOS 7.8.2003 的有效解决方案:

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，取消注释这 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
