title: Conda stopped working
body: <p>I was installing pymc through conda, and it told me to update a few of the files so no problem. However, after updating, it gave an OSError, and now, I cannot access any conda build commands. Now, when I type any conda command, it gives me</p>
  
  <pre><code>-bash: conda: command not found
  </code></pre>
  
  <p>I checked the bash_profile, and .bashrc, and both have the appropriate PATH for conda, and most modules installed through conda still works. Running python and checking the version yields </p>
  
  <pre><code>Python 2.7.11 :: Anaconda custom (x86_64)
  </code></pre>
  
  <p>Looking at the ~/anaconda/bin, I see that the conda folder is not there. Is there anyway to fix this? Is the only solution to re-install anaconda?</p>
  
  <p>Sorry, I do not have any of the terminal outputs since I closed all my windows. Also, I didn't realize I was running Jupyter notebook in the background, but this shouldn't have a problem. Jupyter no longer runs, and yields the error</p>
