title: I got this error in Python, EnvironmentNotWritable Error
body: <p>I ran 'conda install pandas-datareader' in Python to get the data. 
  A EnvironmentNotWritable Error has appeared, as shown below.
  I suspect it is due to the (read only) option in base environment, but I do not know how to fix it.</p>
  
  <p>I have just started Python and have little knowledge. I hope you can help me. </p>
  
  <p>I do not know if it's necessary, but the version is like this.</p>
  
  <pre><code>active environment : None
  conda version : 4.6.11
  conda-build version : 3.17.8
  python version : 3.7.3.final.0
  base environment : C:\ProgramData\Anaconda3 (read only)
  </code></pre>
  
  <p>i ran this code </p>
  
  <pre><code>conda install pandas-datareader
  </code></pre>
  
  <p>During the installation of the package, the following error message appears.</p>
  
  <pre><code>....
  Preparing transaction: done
  Verifying transaction: failed
  
  EnvironmentNotWritableError: The current user does not have write permissions to the target environment.
