title: Creating new Anaconda environment
body: <p>I have problems creating a new Anaconda environment. I am new to Python and Anaconda and in another thread (<a href="https://stackoverflow.com/questions/59561768/customize-axes-in-matplotlib">Customize axes in Matplotlib</a>) I was asked to create an new environment because apparently I was using an old version of some packages (Pandas, Matplotlib and also from Jupyter).</p>
  
  <p>So I inserted the following comments in the Anaconda prompt:</p>
  
  <pre><code>conda update conda
  conda create -n myenv python=3.7
  </code></pre>
  
  <p>Both of them could be executed without an error and a new environment was created in Anaconda. I was further told to use the following comment:</p>
  
  <pre><code>conda activate myenv
  source activate myenv 
  </code></pre>
  
  <p>Both of them lead to error messages. The first one leads to the message "CommandNotFoundError: 'activate'" and the second one to "The instruciton source is either spelled wrong or could not be found" (translated from German). The helping person from the other thread told me to ask this in a separate question because, he or she does not know, what the problem might be. Does anyone of you have an idea.</p>
