expo sdk 40 metro.config.js“期望'fromDir‘为'string'，得到'undefined’”

Question

我在一个带有yarn工作区的monorepo上，我也在使用react-native-svg-transformer。我已经将sdk更新到sdk 40，并且我在metro.config.js中有这个错误：

​

这就是我的metro.config.js：

const { createMetroConfiguration } = require('expo-yarn-workspaces');
const { getDefaultConfig } = require('@expo/metro-config');
const configuration = createMetroConfiguration(__dirname);
module.exports = (async () => {
  const {
    resolver: { sourceExts },
  } = await getDefaultConfig();
  return {
    transformer: {
      babelTransformerPath: require.resolve('react-native-svg-transformer'),
    },
    resolver: {
      ...configuration.resolver,
      assetExts: configuration.resolver.assetExts.filter(ext => ext !== 'svg'),
      sourceExts: [...sourceExts, 'svg'],
      // NOTE: using native entrypoint because bug in metro https://github.com/facebook/metro/issues/485
      resolverMainFields: ['native', 'module', 'browser', 'main'],
    },
  };
})();  

如果你有什么想法？

Answer 1

在await getDefaultConfig()中添加__dirname参数，这样它就应该是await getDefaultConfig(__dirname)

根据docs的要求
