当我运行 webpack-dev-server 时，它只编译带有已编译 .js 和 .js.map 文件路径的 manifest.json 文件。
当我启动 rails server 时，我可以在谷歌控制台中看到它找不到已编译的 js 文件:
获取 http://localhost:3001/packs/js/application-f382a9fe03d59bcf5484.js net::ERR_ABORTED 404(未找到)
如何解决？
这是我的 config/webpack/development.js
process.env.NODE_ENV = process.env.NODE_ENV || 'development'
const environment = require('./environment')
environment.config.output.filename = '[name]-[hash].js'
module.exports = environment.toWebpackConfig()
应用程序.html.erb

最佳答案
我有同样的问题，通过更新 config/webpack/development.js 解决
process.env.NODE_ENV = process.env.NODE_ENV || 'development'
const environment = require('./environment')
const config = environment.toWebpackConfig();
config.output.filename = "[name].js"
module.exports = config;
