installation finished.
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! Share your notebooks and packages on Anaconda Cloud!
Sign up for free: https://anaconda.org
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
