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

<!DOCTYPE html>
<html>
<head>
<title>Top</title>
<meta name="viewport" content="width=device-width,initial-scale=1">
<%= csrf_meta_tags %>
<%= csp_meta_tag %>

<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>

</head>

<body>
<%= yield %>
</body>
</html>

# Reload manifest.json on all requests so we reload latest compiled packs

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;
