Rails/NPM - babel-loader 的模块构建失败 [ERR_PACKAGE_PATH_NOT_EXPORTED]

Question

我有一个 Rails 应用程序，最近发生了一些变化，rails server 将启动，但是当我加载页面时，我在浏览器控制台中收到与 NPM 相关的错误。我没有在这个应用程序中设置 NPM/VueJS，所以需要一些帮助才能让它在本地运行......

Error: Module build failed (from ./node_modules/babel-loader/lib/index.js):

这与最近在 this SO post 中报告的问题相似，但在这种情况下，NPM 并未嵌入到 Rails 应用程序中。不管我尝试了他们的解决方案，删除了node_modules（没有package-lock.json）并运行npm install，但这会导致shell中出现更多错误：

$ npm install
npm WARN deprecated postcss-cssnext@3.1.0: 'postcss-cssnext' has been deprecated in favor of 'postcss-preset-env'. Read more at https://moox.io/blog/deprecating-cssnext/

这个应用程序正在生产中，所以我目前对更新过时的库不感兴趣。我不是 NPM/JS 专家，所以无论这可能多么初级，我都会很感激任何建议。谢谢！

编辑：yarn install --check-files 根据请求的结果

$ yarn install --check-files
yarn install v1.22.4

Answer 1

您在项目中使用纱线吗？如果是这样试试：

yarn install --check-files

请发布您的终端结果。

Answer 2

这是我的情况，只需删除 node_modules 和 package-lock.json 并运行 npm installso npm run build 正常工作。show here for this answer
