conda how do I activate environments
<p>I am struggling to activate conda environments I have created on mac os x. 
Here are the environment that I have created.</p>

<pre><code>$: conda env list
# conda environments:
#
py34                     /Students/rt12083/anaconda3/envs/py34
py35                     /Students/rt12083/anaconda3/envs/py35
root                  *  /Students/rt12083/anaconda3
</code></pre>

<p>When I try to activate them I get the following error:</p>

<pre><code>$: source activate py34
activate: No such file or directory.
</code></pre>

<p>When i run the command <code>which activate</code> I get the following:</p>

<pre><code>which activate
/Students/rt12083/anaconda3/bin/activate
</code></pre>

<p>my <code>path</code> variable is:</p>

<pre><code>garnet: echo $PATH

/sw/bin:/sw/sbin:.:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11R6/bin:/usr/local/bin:/    Developer/Tools:/usr/local/GMT4.5.7/bin:/usr/local/TauP/bin:/usr/local/SU/bin:/usr/local/sac/bin:/usr/local/sac/iaspei:/usr/local/sac/macros:/Students/rt12083/anaconda3/bin
</code></pre>

<p>What do I need to do to activate the environments?</p>
