WARNING:
    You currently have a PYTHONPATH environment variable set. This may cause
    unexpected behavior when running the Python interpreter in Miniconda2.
    For best results, please verify that your PYTHONPATH only points to
    directories of packages that are compatible with the Python interpreter
    in Miniconda2: /home/xudl/soft/miniconda2
Do you wish the installer to prepend the Miniconda2 install location
to PATH in your /home/xudl/.bashrc ? [yes|no]
[no] >>> 

You may wish to edit your .bashrc or prepend the Miniconda2 install location:

$ export PATH=/home/xudl/soft/miniconda2/bin:$PATH

Thank you for installing Miniconda2!

在安装过程中，会提示修改PATH系统变量，根据需求输入yes或者no就可以了

我这里选择了no ， 后续再调用的时候后就需要使用完整的路径了

安装好之后，可以测试一下，这里我升级一下conda, 确保是最新版本：

/home/xudl/soft/miniconda2/bin/conda update conda

Solving package specifications: .

Package plan for installation in environment /home/xudl/soft/miniconda2:
