title: Cant activate virtual environment
body: <p>I am a bit of a newbie and made a virtualenvironment to connect to jutyer notebook as a kernel and I see the kernel when I open jp but cannot activate the virtual environment in the terminal.</p>
  <p>To recreate what I had done</p>
  <pre><code>virtualenv myenv
  source myenv/bin/activate
  pip install --user ipykernel
  pip install ipykernel
  python -m ipykernel install --name=myenv
  </code></pre>
  <p>and now I get</p>
  <pre><code>$ source myenv/bin/activate
  -bash: myenv/bin/activate: No such file or directory
  </code></pre>
  <p>and</p>
  <pre><code>lsvirtualenv -b
  command not found
  </code></pre>
  <p>My available kernels are</p>
  <pre><code>  myenv      /Users/me/Library/Jupyter/kernels/myenv
  </code></pre>
