安裝NetCore 2.0 + Node.js + npm

1. 下載 Node.js 套件清單 (若無額外下載清單則會安裝到很舊的版本，且會有各種奇奇怪怪的錯誤跑出來)

   curl -sL https://deb.nodesource.com/setup_8.x -o nodesource_setup.sh sudo bash nodesource_setup.sh
   sudo bash nodesource_setup.sh

2. 安裝 Node.js + npm

   sudo apt-get install nodejs

3. 下載 NetCore 套件清單

   curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
   sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg
   sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-xenial-prod xenial main" > /etc/apt/sources.list.d/dotnetdev.list'

4. 開始安裝 NetCore 2.0

   sudo apt-get update
   sudo apt-get install dotnet-sdk-2.0.2

5. 等他跑完就可以囉
