1. Q&A
1.1. TypeError: Cannot convert object to primitive value
当 object 不是字符串时
console.log("string" + object);
改成
console.log(object);
1.2. 文件路径
只有在 require() 时才使用相对路径(./, ../) 的写法，其他地方一律使用绝对路径，如下：
// 当前目录下
path.dirname(__filename) + '/test.js';
// 相邻目录下
path.resolve(__dirname, '../lib/common.js');
1.3. Not compatible with your operating system or architecture: fsevents
Since fsevents is an API in OS X allows applications to register for notifications of changes to a given directory tree. Running:
npm install --no-optional
