我的操作系统是CentOS Linux 7.4.1708版本。
首先,我安装了Anaconda的Python环境。然后我替换了默认的/usr/bin/python中的Python环境。
$ ll /usr/bin/python*
lrwxrwxrwx. 1 root root 7 Aug 15 03:40 /usr/bin/python -> python2
lrwxrwxrwx. 1 root root 9 Aug 9 22:10 /usr/bin/python3 -> python3.6
lrwxrwxrwx. 1 root root 29 Aug 9 22:10 /usr/bin/python2.7 -> /root/anaconda2/bin/python2.7
lrwxrwxrwx. 1 root root 29 Aug 9 21:59 /usr/bin/python3.6 -> /root/anaconda3/bin/python3.6
lrwxrwxrwx. 1 root root 9 Aug 8 23:49 /usr/bin/python2 -> python2.7

所以我不能再使用yum了。
$ 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:
2.7.15 |Anaconda, Inc.| (default, May 1 2018, 23:32:55)
[GCC 7.2.0]
If you cannot solve this problem yourself, please go to
the yum faq at:

我试图将 vi /usr/bin/yum
第一行修改为其他任何Python路径,但无效。
此外,我正在尝试像这样重新安装python*.rpm:
rpm -ivh python-tools-2.7.5-68.el7.x86_64.rpm python-2.7.5-68.el7.x86_64.rpm python-libs-2.7.5-68.el7.x86_64.rpm tkinter-2.7.5-68.el7.x86_64.rpm
我尝试重新安装yum*.rpm
(今天我下载了很多*.rpm
...),但是还是没有解决问题。有人可以帮助我吗?谢谢!
--force
