CentOS7 yum安装的rh-python3.8升级pip后报错ModuleNotFoundError: No module named ‘pip’ 修复

CentOS7用yum安装rh-python3.8后，原始pip版本为19.9，用命令行升级后在运行该版本的pip就会报错No module named ‘pip’

修复过程：

1.使用python3.8 -m ensurepip --upgrade修复并升级该版本python的pip到最新版本，pip二进制文件在 /opt/rh/rh-python38/root/local/bin/ 目录下

2.复制 site-packages 目录下的 pip pipxxx.dist-info到系统注册的路径下即：

示例命令行
cp -r /opt/rh/rh-python38/root/usr/local/lib/python3.8/site-packages/pip /opt/rh/rh-python38/root/lib/python3.8/site-packages/

# 复制site-package/pip-xxxx.dist-info目录
cp -r /opt/rh/rh-python38/root/usr/local/lib/python3.8/site-packages/pip-25.0.1.dist-info /opt/rh/rh-python38/root/lib/python3.8/site-packages/

# 复制site-package/pip目录
cp -r /opt/rh/rh-python38/root/usr/local/lib/python3.8/site-packages/pip /opt/rh/rh-python38/root/lib/python3.8/site-packages/

# 复制site-package/pip-xxxx.dist-info目录
cp -r /opt/rh/rh-python38/root/usr/local/lib/python3.8/site-packages/pip-25.0.1.dist-info /opt/rh/rh-python38/root/lib/python3.8/site-packages/

3.重新创建pip3.8的软链接

示例命令行：

ln -snf /opt/rh/rh-python38/root/local/bin/pip3.8 /opt/rh/rh-python38/root/bin/pip3.8
ln -snf /opt/rh/rh-python38/root/local/bin/pip3 /opt/rh/rh-python38/root/bin/pip3
ln -snf /opt/rh/rh-python38/root/local/bin/pip /opt/rh/rh-python38/root/bin/pip

 

ln -snf /opt/rh/rh-python38/root/local/bin/pip3.8 /opt/rh/rh-python38/root/bin/pip3.8
ln -snf /opt/rh/rh-python38/root/local/bin/pip3 /opt/rh/rh-python38/root/bin/pip3
ln -snf /opt/rh/rh-python38/root/local/bin/pip /opt/rh/rh-python38/root/bin/pip
