Rails/NPM-Babel-Loader的模块构建失败[ERR_PACKAGE_PATH_NOT_EXPORTED] [英] Rails/NPM - Module build failed [ERR_PACKAGE_PATH_NOT_EXPORTED] for babel-loader

问题描述

我有一个Rails应用程序，最近更改了一些东西，rails server将启动，但当我加载一个页面时，我在浏览器控制台中得到了一个与NPM相关的错误。我没有在此应用程序中设置NPM/VueJS，因此需要一些帮助使其在本地运行...

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

这类似于this SO post最近报告的一个问题，但在这种情况下，NPM没有嵌入到Rails应用程序中。尽管如此，我还是尝试了他们的解决方案，方法是删除node_modules(没有package-lock.json)并运行npm install，但这会导致外壳程序中出现更多错误：

$ 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/
npm WARN deprecated mkdirp@0.5.4: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)

npm ERR! code 1
npm ERR! Command failed: git checkout ^2.4.0

此应用程序正在生产中，因此我目前对更新过时的库不感兴趣。我不是NPM/JS专家，所以无论这些建议多么初级，我都将不胜感激。谢谢！

编辑：根据请求yarn install --check-files结果

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

推荐答案

在我的情况下，只需删除NODE_MODULES和Package-lock.json并运行npm install，npm run build即可正常工作。show here for this answer
