I don't understand the --python=python2?

I don't understand why --python=python2 knows to download bcrypt? Also, there are other packages in the package.json file, will this load them as well?

It is not the --python=python2 that tells npm to download bcrypt. Below is the npm command to install bcrypt

npm install bcrypt --python=python2

The npm install bcrypt part tells npm to install that package, but bcrypt depends on a python version between 2.5 and 3.0 and python in workspace is version 3.4.1, i.e., the python command refers to a wrong version. In workspace python2 refers to python version 2.7.5, so therefore we need to tell npm that it should use python2 instead of python. That is exactly what

 --python=python2

means.
