最近闲来没事，又开始继续我的RN项目，由于有一段时间没有做了，想重新建一个项目，按照之前的顺序。（前提环境已经装好）
环境 mac 版本10.12.5
1.默认情况下安装react-native init MyTestApp
2.cd MyApplication
3.npm start
4.react-native run-ios
以上是我默认的步骤进行工程的创建，但是在运行的总是失败。
错误信息
“Unpacking /Users/XXXX/.rncache/double-conversion-1.1.5.tar.gz...”

然后查询资料：最常见的说法是修改package.json :"
dependencies": {
"react": "16.0.0-alpha.12",
"react-native": "0.48.3"
},
修改为：
dependencies": {
"react": "16.0.0-alpha.6",
"react-native": "0.44.3"
},
然后删除这个目录下的node_modules 这个文件夹 然后重新 node install.
相当于重新安装了react ，react-native 的版本。但是运行后还是报错。最后我用
xcode打开工程后发现 在react目录下缺少文件依赖（.rncache这个目录下的文件）。网上说有可能是被墙的原因。所以这个版本（0.48.3）可能会出问题。我觉的应该试试0.44.3 ，修改package.json后的也没有直接解决 。
于是我在初始化创建的时候进行一个0.48.3版本，直接用默认的选项。
命令：
react-native init MyApplication --version 0.44.3
完成后 我先运行了npm start ，启动服务后
react-native run-ios
出现了久违的画面。
ps.在默认初始化的时候我将缺少的文件在网上找了一下，找到了一个下载地址，放进去之后，发现还是缺少其他的依赖，这里就不贴出来了。
