title: jupyter notebook installation issue using pip
body: <p>I had a problem with jupyter notebook. Every time I started a notebook, kernel died.</p>
  
  <p>So, I decided to uninstall jupyter notebook using pip:</p>
  
  <pre><code>pip uninstall jupyter notebook
  </code></pre>
  
  <p>After successful uninstallation, I installed again, using same pip:</p>
  
  <pre><code>pip install jupyter notebook
  </code></pre>
  
  <p>Then, as usually, I typed in cmd:</p>
  
  <pre><code>jupyter notebook
  </code></pre>
  
  <p>But got this error:</p>
  
  <p><strong>'jupyter' is not recognized as an internal or external command,
  operable program or batch file.</strong></p>
  
  <p>So I checked the location of IPython, and found out that now the right file, which I want to call is <strong>jupyter-notebook</strong>, which different from <strong>jupyter notebook</strong> by dash sign. If I run <strong>jupyter-notebook</strong> from cmd everything works.</p>
  
  <p>Can anyone explain, what happened and why the file now called jupyter-notebook?</p>
  
  <p>Thank You</p>
