Error: Cannot find module './lib/source-map-generator'

Question

我刚刚从 Github、运行 npm install 和 npm start.

克隆了一个存储库（一个 React Native 项目）

然后运行 metro bundler 将抛出以下错误：

node:internal/modules/cjs/loader:936
  throw err;
  ^

有人知道如何解决上述问题吗？

提前致谢。

Answer 1

尝试删除 node_modules 并重复 npm 安装或 yarn。

如果还是不行，也许可以尝试删除 package-lock.json/yarn.lock 并重复上述操作。

Error: Cannot find module './lib/source-map-generator'

Error: Cannot find module './lib/source-map-generator'

npm-start
