npm config set registry https://registry.npm.taobao.org
npm info underscore

npm config set loglevel warn

Upgrade

upgrade nodejs (minor version, from 6.1 to 6.2)

Just like a fresh new installation.

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs

Note for upgrading Node.js:

Sometimes new version of Node.js is shipping with a new version of V8, existing native addons will need to be recompiled or runtime errors will occur when trying to load them. Use npm rebuild or simply remove your node_modules dir and npm install from scratch.

npm rebuild
upgrade nodejs (major version, from 6.x to 8.x)

Just like a fresh new installation.

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
sudo npm i -g npm
