Jetbrains全系列IDE使用 1年只要46元 售后保障 童叟无欺
直接安装python3.9.5，编译时会报Could not build the ssl module! ，python调用相关代码的时
候，会报ModuleNotFoundError: No module named ‘_ssl’， pip安装相关模块的时候，会报ERROR: Could not find a version that satisfies the requirement ssl (from versions: none)
装好系统后，先sudo yum update更新系统；这时，gcc会报不存在
安装python需要的依赖:
sudo yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make
此时，运行openssl version，会显示OpenSSL 1.0.2k-fips 26 Jan 2017
1、安装 OpenSSL
https://www.openssl.org/ 下载openssl-1.1.1k.tar.gz并解压到openssl-1.1.1k
#./config --prefix=/usr/local/openssl shared
#sudo make 完成后/usr/local/openssl下没有东西
#sudo make install 完成后/usr/local/openssl下有了bin、lib等此时运行openssl version，还会显示安装 OpenSSL 1.0.2k-fips 26 Jan 2017，但cd /usr/local/openssl/bin openssl version,会显示OpenSSL 1.1.1k 10 Sep 2019
sudo chmod 777 /usr/local/openssl
sudo chmod 777 /usr/local/openssl/bin
sudo chmod 777 /usr/local/openssl/lib2、安装 LibreSSL
http://www.libressl.org/ 下载源代码。此处使用“libressl-2.8.2.tar.gz”下载解压
#./config --prefix=/usr/local/openssl shared
#sudo make
#sudo make install此时/usr/local/openssl/bin/openssl version会显示error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory
#sudo ln -s /usr/local/openssl/lib/libssl.so.1.1 /usr/lib64/libssl.so.1.1
#sudo ln -s /usr/local/openssl/lib/libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.1
/usr/local/openssl/bin/openssl version显示OpenSSL 1.1.1k 10 Sep 2019
#sudo mv /usr/bin/openssl /usr/bin/openssl.bak
#sudo ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
#openssl version显示LibreSSL 2.8.2
3、安装 Python3.9.5
export LDFLAGS=”-L/usr/local/openssl/lib”
export CPPFLAGS=”-I/usr/local/openssl/include/openssl”
export PKG_CONFIG_PATH=”/usr/local/openssl/lib/pkgconfig”解压Python-3.9.5.tar.xz
cd Python-3.9.5
./configure --prefix=/usr/local/python39
sudo make
sudo make install安装正确会提示已安装pip、pip3，在/usr/local/python39/bin下，可以添加到环境变量路径。
/usr/local/python39/bin/pip3 install pyqt5
/usr/local/python39/bin/pip3 install pyqt5-tools/usr/local/python39/bin/python3.9 test1.py验证安装，显示窗体
