Anaconda installation Conda problem is not available

The error message is as follows:

Load error:in C:\Users\username.condarc on line 4, column 0. Invalid YAML

In the knowledge to see a anaconda Amway (installation) tutorial, very useful, the first time the installation Anaconda did not appear any problems, but after a period of time, in the cmd input Conda, the above error. In the network did not find the right help information, do not know exactly where the problem, reinstall Anaconda2, try again, or appear above the problem, but the input Python Ipython and Jupyter notebook, are normal ~
DMS Bo main section of grass, immediately get reply (Super moved):

Condarc is the Conda configuration file. Find the file and see what's inside.
The error is illegal YAML file

You can find a usable condarc, copy the content of others to try

The contents of my own Condarc file are:

Ssl_verify: ' True '
Nda-fusion
-https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
-Defaults
Show_channel_urls:true
Ssl_verify: ' True '

There are no available condarc on the web, but they are still being inspired and the Final solution is:
Delete the old Condarc file , re-enter the Conda, there is no problem:

C:\users\username>conda
usage:conda-script.py [-h] [-v] command ...
