我的 CentOS yum 更新没有运行。请检查下文中的 yum 错误消息。
yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named yum
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:
2.7.16 (default, Oct 15 2019, 11:56:22)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-17)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
将 python 和 pip 更新至最新版本。当前版本为：
- Python 2.7.16 pip 19.3.1 来自
- /usr/local/lib/python2.7/site-packages/pip (python 2.7)
我从目录中看到这个文件/usr/bin/yum
#!/usr/local/bin/python2.7
import sys
try:
import yum
except ImportError:
print >> sys.stderr, """\

您可以使用 scp 将 python 从其他服务器复制到焦点 python 包，如 ->> 复制库完成后。yum命令与我的服务器一起工作：
scp -r [email protected]:/usr/lib/python2.7/site-packages /usr/lib/python2.7/
