或修改~/.npmrc文件(没有就自行新建一个)，写入registry = https://registry.npm.taobao.org

配置后可通过下面方式来验证是否成功

npm config get registry

	// toString(radix)
	// 任意数值转为指定进制
	0x6600.toString(2) // "110011000000000"

	// parseInt(value, radix)
	// 将value作为指定进制radix来解析，得到10进制结果
	parseInt("110011000000000",2) // 26112

	// 任意进制相互转换
	// 先转10进制，再换成目标进制
