Question

我已经向我的本地响应项目添加了内容，以分析为什么我的发布版本失败。但是我却遇到了另一个问题。我有一个带有以下config的webpack.haul.js

module.exports = {
    entry: './index.js',
};

当我运行react-native run-android时，我看到以下错误。有人可以帮我吗。

ERROR  Failed to compile.

您的问题是babel的配置不正确，无法编译这些错误中提到的代码中存在的功能。

具体问题：

静态方法属性（您需要https://babeljs.io/docs/en/babel-plugin-proposal-class-properties）
流类型（您需要https://babeljs.io/docs/en/babel-plugin-transform-flow-strip-types）

很难确切地说出您的配置出了什么问题，但是一种更快的测试方法是直接在这些文件上运行babel CLI。如果您确保BABEL_ENV和任何其他babel cli / env / API标志的设置方式与webpack构建中的设置方式相同（您可能必须进行一些调试才能找到应用babel-loader的位置），您可以执行例如yarn run babel node_modules/native-base-shoutem-theme/src/StyleProvider.js

如果您可以重现这样的问题，则可以对babel配置进行更深入的尝试，直到找到解决方案为止。

一个很好的起点是更新babel和已安装的所有预设/插件。
