Question

我正在使用Detox 9.0.4和React-native 0.57.2，并试图模拟文件。在他们的documentation之后，我在运行构建时添加了$ dig @g.root-servers.net red. NS +nocookie ; <<>> DiG 9.12.0 <<>> @g.root-servers.net red.

这很好，直到我们将React-Native升级到使用更新的Metro Bundler的0.57，所以我相应地更改了getSourceExts: () => process.env.RN_SRC_EXT ? process.env.RN_SRC_EXT.split(',') : []：

rn-cli.config.js

但是rn-cli.config.js导致常规构建失败。

我该如何解决？

Answer 1

如果您未明确指定新语法，则新语法似乎不会使用JS文件，因此解决方案是在每种情况下都添加它。

rn-cli.config.js文件：

const blacklist = require('metro-config/src/defaults/blacklist');

module.exports = {
  resolver: {
    blacklistRE: blacklist([/react-native\/local-cli\/core\/__fixtures__.*/]),
    sourceExts: process.env.RN_SRC_EXT ? process.env.RN_SRC_EXT.split(',') : []
  }
};

当您传递RN_SRC_EXT变量（在我的例子中是在npm命令中）时，我还传递了'js'作为第二个扩展名：

"test:e2e-build": "RN_SRC_EXT='e2e.js,js' detox build -c ios.sim.release"

排毒模拟文件
