Why_Is_This_Hard
<p>After having to completely re-install an OS and setup a development environment. attempting to run the plutus-playground-server after building it wiht <code>nix-build -A plutus-playground.server</code> once in nix-shell I get the error:</p>
<pre><code>[nix-shell:~/plutus-apps/plutus-playground-server]$ plutus-playground-server
plutus-playground-server: for development use only
/nix/store/fm77y43lzpgnay4pyc48jwpln0lnmrk3-plutus-playground-server/bin/plutus-playground-server: line 3: nix-build: command not found

</code></pre>
