centos 7.9 升级系统默认的python2.7到python 2.7.18
备份旧版本

Download Python | Python.org Python Release Python 2.7.18 | Python.org wget https://www.python.org/ftp/python/2.7.18/Python-2.7.18.tgz
cd /home/soft tar -xzf Python-2.7.18.tgz cd Python-2.7.18 mkdir /usr/local/python2.7.18/ ./configure --prefix=/usr/local/python2.7.18 make && make install ? #### ? ln -s /usr/local/python2.7.18/bin/python2.7 /usr/bin/python ln -s /usr/local/python2.7.18/bin/python /usr/local/bin/python
centos的python升级安装完成。
安装 pip
curl "https://bootstrap.pypa.io/pip/2.7/get-pip.py" -o "get-pip.py" ? python get-pip.py ? ln -s /usr/local/python2.7.18/bin/pip /usr/bin/pip
centos中yum指令报错No module named yum解决
vi /usr/bin/yum #!/usr/bin/python2.7 import sys try: ? import yum except ImportError: ? print >> sys.stderr, """\ There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: ? ? %s ? Please install a package which provides this module, or verify that the module is installed correctly. ? It's possible that the above module doesn't match the current version of Python, which is: %s ? If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq ? """ % (sys.exc_value, sys.version) ? sys.exit(1) ? sys.path.insert(0, '/usr/share/yum-cli') try: ? import yummain ? yummain.user_main(sys.argv[1:], exit_code=True) except KeyboardInterrupt, e: ? print >> sys.stderr, "\n\nExiting on user cancel." ? sys.exit(1) ?
将上述文件第一行
#!/usr/bin/python 修改为: #!/usr/bin/python2.7
重新yum即可正常
