title: How to deal with "[Errno 122] Disk quota exceeded" problem when creating new environment by anaconda?
body: <p>I am trying to create a new environment for Python through Anaconda. But the error keeps coming out saying :</p>
  
  <pre><code>Solving environment: failed
  
  # &gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt; ERROR REPORT &lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;
  
      OSError: [Errno 122] Disk quota exceeded
  </code></pre>
  
  <p>I am using the sentence below to create the new environment: </p>
  
  <pre><code>conda create --name cpost python=2.7 numpy=1.9
  </code></pre>
  
  <p>I understand that this might be related to the working directory, which is really limited in disk quota. So I copied the Anaconda directory fully to a larger disk-quota directory, and tried to create again. The same error came out. As I checked the error information, I noticed the following lines:</p>
  
  <pre><code>$ /nuist/u/home/liangxz/anaconda3/bin/conda create --name cpost python=2.7 numpy=1.9`

  <p>I realized that the "user config file" is <code>/nuist/u/home/liangxz/.condarc</code>, and the "base environment" is <code>"/nuist/u/home/liangxz/anaconda3  (writable)"</code>, which means even I copied an anaconda to a larger quota directory, the "writable directory" did not change and remained the small quota directory.(<code>/nuist/u/home/liangxz/</code> is the small quota directory)</p>
  
  <p>So my question here is how can I change the "base environments" and "envs directories" to the desired larger quota directory? Can I change it directly through some fixings? Or I must install Anaconda again in the bigger directory?</p>
