我该怎么办？知道我试过这个命令 conda install -c anaconda lxml = 3.6.0 我按摩了这个按摩

The following packages will be UPDATED:

        conda-env: 2.5.0-py27_0 anaconda --> 2.5.2-py27_0 anaconda

The following packages will be SUPERCEDED by a higher-priority channel:

    lxml:      3.6.0-py27_0          --> 3.6.0-py27_0 anaconda

我看到您报告的两个问题：

您在访问anaconda.org时遇到问题。尝试ping它以查看它是否已关闭，检查您的连接，和/或查看该服务是否暂时停止...
我已经在Anaconda-Python3.5和Canopy1.7（Python 2.7）上进行了测试，并且两者都使用了lxml 3.6和html5lib 0.999。您有相同的lxml但似乎有不同版本的html5lib。

您最好的选择是更新html5lib，尝试更新lxml（如果这还不够），或者如果不起作用，请向Continuum报告问题。 2在他们的包装解析中可能存在一些不兼容性。同时，如果你想留在Python2上，可以试试Anaconda-Python3.5或Canopy1.7（见tutorial instructions）。

我有lxml但仍然要求我安装它
