CentOS 7升级Python到3.6.6后yum出错问题解决总结

 

   最近将一台测试服务器操作系统升级到了Cent0S 7.5,然后顺便也将Python从2.7.5升级到Python 3.6.6,升级完成后,发现yum安装相关包时出现异常,报File “/usr/libexec/urlgrabber-ext-down”, line 28这样的错误, 具体错误信息如下所示:

 

# yum install openssl

 

……………………..

Total download size: 1.7 M

Is this ok [y/d/N]: y

Downloading packages:

Delta RPMs disabled because /usr/bin/applydeltarpm not installed.

  File “/usr/libexec/urlgrabber-ext-down”, line 28

    except OSError, e:

                  ^

SyntaxError: invalid syntax

  File “/usr/libexec/urlgrabber-ext-down”, line 28

    except OSError, e:

                  ^

SyntaxError: invalid syntax

 

  测试、验证了一下,可以用下面这种方法解决这个问题:

 

修改/usr/libexec/urlgrabber-ext-down中的Python版本信息

 

vi /usr/libexec/urlgrabber-ext-down 将/usr/bin/python改为/usr/bin/python2.7。
