反應本土的init：的ReferenceError：BABEL]未知選項：未知選項：base.optional

一旦運行react-native init testNative反應本土的init：的ReferenceError：BABEL]未知選項：未知選項：base.optional

ReferenceError: [BABEL] /Users/m/git/testNative/node_modules/react-native/local-cli/bundle/bundle.js: Unknown option: base.optional

我試過在以下職位的建議，我發現了以下錯誤（https://github.com/facebook/react-native/issues/5 ，https://github.com/babel/babel-loader/issues/132,https://github.com/babel/babelify/issues/129,React 0.14 error: Module build failed: ReferenceError: [BABEL] .../node_modules/eslint-loader/index.js!/.../main.jsx: Unknown option: base.stage），但無濟於事。

我目前的假設是因爲我的系統上沒有任何地方的.babelrc文件，所以它會回落到「base.optional」。至少將一個.babelrc文件添加到我的項目文件夾是唯一產生不同結果的東西（降級節點，babel或react-native什麼也不做）。所以，如果這是解決方案，有沒有人知道我的.babelrc文件應該包括一個react-native項目？

感謝

這裏是.babelrc文件，您可以與您的RN項目中使用的一個。注意在RN工作正常，沒有.babelrc文件在您的項目（它退到node_modules/react-native/.babelrc文件

{ 
    "retainLines": true, 
    "compact": true, 
    "comments": false, 
    "plugins": [], 
    "presets": ["stage-0", "react", "react-native"], 
    "sourceMaps": false, 
}

您還需要將這些行添加到您package.json文件並安裝DEV-依賴關係：npm i --save-dev <package-name>

"devDependencies": { 
    "babel-preset-react": "^6.3.13", 
    "babel-preset-react-native": "^1.4.0", 
    "babel-preset-stage-0": "^6.3.13" 
}
