Parse and Heroku Service(1)Heroku Installation and Play

Parse and Heroic Service(1)Heroku Installation and Play

1 Introduction Parse Service
a. JSON format data mapping to storage
b. PFUser user management
c. iOS and Android push notification
d. File storage

2 Installation of Parse Tool
Command Line Tool
> curl -s https://www.parse.com/downloads/cloud_code/installer.sh | sudo /bin/bash

This will install one file under /usr/local/bin/parse. Verify the installation.
> parse version
3.0.5

Check NodeJS version because I am using NodeJS.
https://nodejs.org/en/download/releases/

Some related versions
https://nodejs.org/download/release/v0.12.2/

Error Message with node package node-sass
npm ERR! node-sass@3.0.0 postinstall: `node scripts/build.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the node-sass@3.0.0 postinstall script 'node scripts/build.js'.
npm ERR! Make sure you have the latest version of node.js and npm installed.

Solution:
> xcode-select --install

> npm install -g npm@latest

These does not help.
> cd /usr/local/lib/

> sudo ln -s ../../lib/libSystem.B.dylib libgcc_s.10.5.dylib

This does not help.

Try different version  wget https://nodejs.org/dist/v4.4.0/node-v4.4.0.tar.gz

With the version 4.4.0 and upgrade the version of     "node-sass": "~3.4.2”, It works pretty well.

3 Heroku Introduction
https://dashboard.heroku.com/apps

Install Heroku Tool Belt
On MAC, just directly download the binary file and install.

On Linux, make sure we already have the ruby there. (why ruby? I just personally do not like ruby that much.)
> ruby --version
ruby 2.0.0p648 (2015-12-16) [x86_64-linux]

For ubuntu
> wget -O- https://toolbelt.heroku.com/install-ubuntu.sh | sh

For CentOS, just choose the standalone version
> wget -qO- https://toolbelt.heroku.com/install.sh | sh

> echo 'PATH="/usr/local/heroku/bin:$PATH"' >> ~/.profile

> . ~/.profile
