title: I can not activate virtual environment in conda
body: <p>I create a virtual environment with conda</p>
  
  <pre><code>$ conda create test_env numpy .....
  </code></pre>
  
  <p>It gets created successfully. </p>
  
  <pre><code>$ conda env list
  # conda environments:
  #
  base                  *  /home/myname/anaconda3
  my_project_env           /home/myname/anaconda3/envs/my_project_env
  test_env                 /home/myname/anaconda3/envs/test_env
  </code></pre>
  
  <p>but I can not activate it</p>
  
  <pre><code>$ source activate my_project_env
  </code></pre>
  
  <p>returns - activate: No such file or directory </p>
  
  <p>The only place I find <em>activate</em> is within the whole anaconda3 is in /common folder</p>
  
  <pre><code>source anaconda3/envs/my_project_env/lib/python3.6/venv/scripts/common/activate my_project_env
  </code></pre>
  
  <p>When I run it with this path I get <strong>VENV_PROMPT</strong> "kind of environment" but when I check libraries with <em>pip list</em> it returns a global list of installed libraries instead of the selected few.</p>
  
  <pre><code>$ source anaconda3/envs/my_project_env/lib/python3.6/venv/scripts/common/activate my_project_env
  __VENV_PROMPT__myname@box:~$ pip3 list
  </code></pre>
