唔。找了很久。最後發現竟然是yum 有問題。emmmmm 報錯如下：

[root@iZdt4mpwkybe8hZ tmp]# yum install wget  There was a problem importing one of the Python modules required to run yum. The error leading to this problem was:

   No module named yumPlease 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 (default, Jun  5 2018, 13:52:24) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]If you cannot solve this problem yourself, please go to 
the yum faq at:
  http://yum.baseurl.org/wiki/Faq

看著網上哪些人說，修改一下/use/bin/yum

修改了第一行為

[root@iZdt4mpwkybe8hZ tmp]# vi /usr/bin/yum 

#!/usr/bin/python2import systry:
    import yum
except ImportError:
    print >> sys.stderr, """\There was a problem importing one of the Python modules

emmm 結果很尷尬的

唔看了一下報錯。發現沒有這個模塊，那麽pip 安裝一個把

唔安裝成功，那麽再用一下yum 把

唔還是報錯。安裝一下pycurl 把

    ----------------------------------------Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-xDCpxU/pycurl/

emmm 竟然報錯. tmd 那麽就編譯一個把

下載pycurl：http://pycurl.sourceforge.net/download/pycurl-7.19.0.tar.gztar xzf pycurl-7.19.0.tar.gz
python setup.py install

然後測試一下

[root@iZdt4mpwkybe8hZ tmp]# python 
Python 2.7.15 (default, Jun  5 2018, 13:52:24) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux2Type "help", "copyright", "credits" or "license" for more information.>>> import pycurl>>>

如果出現問題。那麽就這樣編譯

提示如下錯誤：Traceback (most recent call last):
  File "<stdin>", line 1, in ?ImportError: No module named pycurl檢查一下，原來是pycurl自己假定的curl路徑不對。需要給pycurl指定curl-config 路徑，如下所示：python setup.py install --curl-config=/usr/local/bin/curl-config問題很小，有點隱蔽

唔搞定了！！！！！
