Resolved - Error: Could not load the bindings file. Tried

I ran into this issue when running starting my nodejs app using pm2. For some reason, when my app kept on crashing. Upon checking my pm2 logs, I saw the following error message.

Error: Could not locate the bindings file. Tried:
 /opt/zem-web/node_modules/bcrypt/build/bcrypt_lib.node
 /opt/zem-web/node_modules/bcrypt/build/Debug/bcrypt_lib.node
 /opt/zem-web/node_modules/bcrypt/build/Release/bcrypt_lib.node
 /opt/zem-web/node_modules/bcrypt/out/Debug/bcrypt_lib.node
 /opt/zem-web/node_modules/bcrypt/Debug/bcrypt_lib.node

 /opt/zem-web/node_modules/bcrypt/Release/bcrypt_lib.node
 /opt/zem-web/node_modules/bcrypt/build/default/bcrypt_lib.node

The following two commands helped me resolve it on my Ubuntu setup

sudo npm install -g node-gyp
sudo node-gyp rebuild

nodejs 6
