Question

我目前正在使用Python 2.7的Anaconda CDH包裹。我想将它升级到Python 3.5。

我发现一些教程说可以使用此命令conda install python=3.5升级Python版本。但是，我在运行此命令时发现了以下错误。

[root@host ~]# conda install python=3.5
Fetching package metadata ...Could not connect to https://repo.continuum.io/pkgs/free/linux-64/
Could not connect to https://repo.continuum.io/pkgs/pro/linux-64/...
Could not connect to https://repo.continuum.io/pkgs/free/noarch/
Could not connect to https://repo.continuum.io/pkgs/pro/noarch/...
Solving package specifications: ....

The following specifications were found to be in conflict:
  - enum34 -> python 2.6*|2.7*|3.3*
  - python 3.5*
Use "conda info <package>" to see the dependencies for each package.

我想问一下这是否与主机的网络限制或包问题有关。

提前致谢。

祝你好运，鲁卡

Answer 1

错误是说enum34不适用于python3.5。尝试命令：

conda info enum34

Answer 2

请尝试以下conda create -n py35 python=3.5获取更多参考链接
