title: python spyder conda install failure
body: <p>I am new to Python, now I am using Anaconda Spyder as my main Python distribution. I am learning how to use conda to install/update packages. When I read relevant books and searched online, it seemed that All I need to do is to type "conda install " or type "conda update ". When I typed so in my spyder console, I found error message as follows. Where am I wrong here? Thanks for help.</p>

  <p>Someone suggested me to run it in cmd not in Spyder. Here is my output when I run it in cmd. The update of my pandas also fails in cmd line.
