今天新装的一台服务器,打算用yum安装gcc等程序,出现下面的问题: Loading mirror speeds from cached hostfile Traceback (most recent call last): File "/usr/bin/yum", line 29, in <module> yummain.user_main(sys.argv[1:], exit_code=True) File "/usr/share/yum-cli/yummain.py", line 285, in user_main errcode = main(args) File "/usr/share/yum-cli/yummain.py", line 136, in main result, resultmsgs = base.doCommands() File "/usr/share/yum-cli/cli.py", line 434, in doCommands self._getTs(needTsRemove) File "/usr/lib/python2.6/site-packages/yum/depsolve.py", line 99, in _getTs self._getTsInfo(remove_only) File "/usr/lib/python2.6/site-packages/yum/depsolve.py", line 110, in _getTsInfo pkgSack = self.pkgSack File "/usr/lib/python2.6/site-packages/yum/__init__.py", line 887, in <lambda> pkgSack = property(fget=lambda self: self._getSacks(), File "/usr/lib/python2.6/site-packages/yum/__init__.py", line 669, in _getSacks self.repos.populateSack(which=repos) File "/usr/lib/python2.6/site-packages/yum/repos.py", line 279, in populateSack self.doSetup() File "/usr/lib/python2.6/site-packages/yum/repos.py", line 105, in doSetup self.ayum.plugins.run('postreposetup') File "/usr/lib/python2.6/site-packages/yum/plugins.py", line 184, in run func(conduitcls(self, self.base, conf, **kwargs)) File "/usr/lib/yum-plugins/fastestmirror.py", line 197, in postreposetup_hook if downgrade_ftp and _len_non_ftp(repo.urls) == 1: File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 699, in <lambda> urls = property(fget=lambda self: self._geturls(), File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 696, in _geturls self._baseurlSetup() File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 648, in _baseurlSetup self.mirrorurls = self._replace_and_check_url(mirrorurls) File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 691, in _replace_and_check_url print 'YumRepo Error: All mirror URLs are not using ftp, http[s] or file.\n Eg. %s' % misc.to_utf8(skipped) File "/usr/lib64/python2.6/codecs.py", line 351, in write data, consumed = self.encode(object, self.errors) UnicodeDecodeError: 'ascii' codec can't decode byte 0xbc in position 3746: ordinal not in range(128) 下面是解决办法: cd /var/lib/rpm/ rm -f __db.* yum clean all 好了,再次去用yum安装程序就没有问题了.
