安装minicoda3

安装miniconda3初始化的时候发现miniconda3报了warning

warning如下：

You currently have a PYTHONPATH environment variable set. This may cause unexpected behavior when running the Python interpreter in Miniconda3. For best results, please verify that your PYTHONPATH only points to directories of packages that are compatible with the Python interpreter in Miniconda3。

可以暂时清掉python 环境变量，输入以下命令：

export PYTHONPATH=

接着再用miniconda3下载软件也没什么问题了。
