You need to sudo apt-get install build-essential python2.7 to install a compiler and other tools because bcrypt is an addon that needs to be compiled.

ERROR!!!!

  > bcrypt@0.8.7 install /var/www/YOUR_PROJECT_ROOT_DIR/node_modules/bcrypt

You can use both commands for fixing bcrypt addon issue:

sudo apt-get install build-essential python2.7

sudo apt install build-essential

After I installed ubuntu 17.10 I had very similar errors with node-gyp. What worked for me was installing the node-gyp module apt-get install node-gyp
