Parcel command not found when I run npm build

Question

I am trying to create a bundle for openlayers. I have followed the tutorial https://openlayers.org/en/latest/doc/tutorials/bundle.html When I get to npm run build I get the following error.

openmap@1.0.0 build /accounts/linuxuser/web_projects/openmap
parcel build --public-url . index.html
sh: parcel: command not found

When I ls the node_modules folder I get. parcel -> ../parcel-bundler/bin/cli.js . When I cd to the node_modules folder the parcel-bundler folder is not found. When I run npm install --save-dev parcel-bundler I get the following.

  deasync@0.1.15 install /accounts/linuxuser/web_projects/openmap/node_modules/deasync
  node ./build.js
  sh: node: command not found
  openmap@1.0.0 /accounts/linuxuser/web_projects/openmap

I do have npm install.

npm --version
3.5.2

Error after running npm install --save-dev parcel-bundler

 node ./build.js

       index.html
       index.js
       package.json
       node_modules/
