唔、一个用户宝塔登陆界面一直是打转转,

看日志把日志显示

唔。找了很久。最后发现竟然是yum 有问题。emmmmm 报错如下:

[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 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 (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

看着网上哪些人说,修改一下/use/bin/yum

修改了第一行为

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

#!/usr/bin/python2
import sys
try:
    import yum
except ImportError:
    print >> sys.stderr, """\

    yummain.user_main(sys.argv[1:], exit_code=True)
except KeyboardInterrupt, e:
    print >> sys.stderr, "\n\nExiting on user cancel."
    sys.exit(1)

emmm 结果很尴尬的

唔看了一下报错。发现没有这个模块,那么pip 安装一个把

唔安装成功,那么再用一下yum 把

唔还是报错。安装一下pycurl 把

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

emmm 竟然报错.  tmd  那么就编译一个把

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

然后测试一下

[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 linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pycurl
>>> 

如果出现问题。那么就这样编译

提示如下错误:
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: No module named pycurl

检查一下,原来是pycurl自己假定的curl路径不对。
需要给pycurl指定curl-config 路径,如下所示:
python setup.py install --curl-config=/usr/local/bin/curl-config
问题很小,有点隐蔽
