我在将 react-native 更新到 "^0.56.0" 后出现了这个错误:
bundling failed: Error: Plugin/Preset files are not allowed to export objects, only functions. In /Users/ben/vepo/frontend/node_modules/babel-preset-flow/lib/index.js
我尝试了与这里最高得票答案类似的事情，但是针对 babel-preset-flow：

什么都不起作用。有什么想法吗？
编辑：根本没有node_modules/babel-preset-flow文件夹
