'；react native init'；错误：npm错误！命令失败：git fetch-一个源

尝试通过以下方式初始化react-native项目时出错：

react-native init awesomeProject

：

Installing react-native package from npm...
`npm install --save react-native` failed

然后手动运行此npm命令，错误如下所示：

还有我的文件夹权限（想在

\u dev

中初始化应用程序）：

---

我也遇到了同样的问题，通过在已安装的文件夹中授予或获取权限解决了这个问题：

➜  ~  sudo chmod 774 ProjectFolder/*
➜  ~  sudo chown Username ProjectFolder/*
➜  ~  sudo chmod 774 .babel.json 
➜  ~  sudo chown Username .babel.json

以下是创建新的项目CRNA并从世博会运行的两个步骤。

步骤1：如果您已经安装了crna，请跳过此步骤。
npm安装-g创建反应本机应用程序

步骤2：创建react本机应用程序项目

步骤3：cd项目

步骤4：npm开始或纱线开始
