源码安装Python

1.下载需要的Python版本

Python源码地址：https://www.python.org/downloads/source/

2.安装gcc（yum install gcc）

3.解压，配置，安装

tar -zxvf Python-3.8.18.tgz
mkdir /usr/local/Python38
cd Python-3.8.18
./configure --prefix=/usr/local/python38
make -j 8 && make install

4.链接

ln -s /usr/local/python38/bin/python3.8 /usr/bin/python
ln -s /usr/local/python38/bin/pip3 /usr/bin/pip

whl文件安装python库

有网的环境直接用pip，方便快捷：

pip install  xxx

没网的情况下，可以去官网搜索需要的python库下载对应的whl文件进行安装。注意，此时下载的whl安装包一定要是符合自己Python版本和系统处理器位数的版本，下载的库名中cp39代表python3.9版本，想知道系统具体可以安装哪些标签的.whl文件，可以使用pip debug --verbose，兼容的文件标签就会显示。

问题解决

1.ERROR!You probably have to install the development version of the Python package for your distribution.

configure: error: 
  Could not link test program to Python. Maybe the main Python library has been
  installed in some non-standard library path. If so, pass it to configure,
  via the LDFLAGS environment variable.
  Example: ./configure LDFLAGS="-L/usr/non-standard-path/python/lib"

明明有python，为什么还会报这个错误呢？解决方法：安装python-dev。正常可以使用yum或者apt-get命令直接安装python-dev，但如果没有网络，就使用如上的源码下载即可。

2.Caused by SSLError(“Can‘t connect to HTTPS URL because the SSL module is not available.”)

当使用pip install安装python库时，这个错误不期而遇。网上有很多用yum或者apt-get安装openssl或者openssl-dev，不如用源码安装openssl，一次解决问题：

wget https://www.openssl.org/source/openssl-1.1.1n.tar.gz --no-check-certificate 下载openssl1.1.1
tar -zxf openssl-1.1.1n.tar.gz
cd openssl-1.1.1n
./config --prefix=/usr/local/openssl 
make -j && make install 
openssl version

安装完成后记得重新编译安装python：

./configure --prefix=/usr/local/python38 --with-openssl=/usr/local/openssl --with-openssl-rpath=auto
make && make install

3.ModuleNotFoundError: No module named ‘_bz2’

解决方法，安装bzip2和bzip2-devel后重新编译python：

yum install bzip2 bzip2-devel
./configure --prefix=/usr/local/python38 --with-openssl=/usr/local/openssl --with-openssl-rpath=auto
make && make install

7.ERROR: No matching distribution found for typing-extensions

加上–no-deps治标不治本，缺少的typing-extensions也要安装。

pip install --no-deps xxxxx-cp37-cp37m-linux_x86_64.whl
