Home＃index中的Webpacker :: Manifest :: MissingEntryError 显示/Users/khalidhosein/Desktop/myEPKmedia/builder/khalid101/app/views/layouts/embedded_app.html.erb，其中第7行出现：

Webpacker can't find hello_react.js in /Users/khalidhosein/Desktop/myEPKmedia/builder/khalid101/public/packs/manifest.json. Possible causes:
1. You want to set webpacker.yml value of compile to true for your environment
   unless you are using the `webpack -w` or the webpack-dev-server.
2. webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your webpack configuration is not creating a manifest.
Your manifest contains:
{
  "application.js": "/packs/application-68dcba18197451fbb79e.js",

尝试将我的Rails应用程序与React前端连接时出现此错误。我尝试研究和重新配置所有来源的文件。我还重新创建了manifiedt.json文件并打包了库。我正在关注本教程：

https://github.com/natemacinnes/natemacinnes.github.io/blob/master/rails-5-shopify-app-setup.md

如果有人有任何想法，将不胜感激，因为那里没有太多的文档或教程来介绍如何将Rails Shopify API与React连接起来。

Answer 1

可能是您错过了安装npm install的原因。我遇到了您提到的完全相同的问题。只需在您的终端或npm install中输入Dockerfile。我希望这个问题能得到解决。

$ npm install

Answer 2

尽管我没有使用react，但是在新创建的Rails 6应用程序上遇到了相同的错误。重新安装webpacker为我修复了该问题：

bundle exec rake webpacker:install

我想可能是缺少一些依赖关系，或者是旧版本中的错误（我注意到webpack-dev-server版本已升级到3.8.1）。

Answer 3

尝试在 Ubuntu 20.04 中建立新的 Rails 6 应用程序时，我遇到了同样的挑战。

当我启动Rails服务器并转到浏览器时，出现错误消息：

Webpacker::Manifest::MissingEntryError in Books#index
Showing /home/promisepreston/dynamic_authorization/app/views/layouts/application.html.erb where line #9 raised:

Webpacker can't find application in /home/promisepreston/dynamic_authorization/public/packs/manifest.json. Possible causes:
1. You want to set webpacker.yml value of compile to true for your environment
   unless you are using the `webpack -w` or the webpack-dev-server.
2. webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your webpack configuration is not creating a manifest.
Your manifest contains:
{

这是我修复的方式：

问题是我必须在 Rails 6 应用程序中设置webpacker。从 Rails 6 开始，webpacker是默认的JavaScript编译器。这意味着所有JavaScript代码将由webpacker处理，而不是由旧资产管道（也称为sprockets）处理。

要在Rails 6应用程序中安装webpacker，只需运行以下命令：

bundle exec rails webpacker:install

OR

rails webpacker:install

这应该成功安装webpacker及其所有依赖项。

仅此而已。

我希望这会有所帮助

Answer 4

更新到 Rails 5.1 和 Webpacker 5.x 后我遇到了同样的错误

https://github.com/rails/webpacker/blob/5-x-stable/docs/integrations.md#react

现在的命令是 bundle exec rails webpacker:install:react

Answer 5

我在重新安装 webpacker 的新应用程序上遇到了同样的错误。 rails webpacker:install

Answer 6

在尝试了这么多不同的解决方案后，这奏效了！

yarn config set registry https://registry.npmjs.org
rm yarn.lock
yarn

然后再次安装 webpack

bundle exec rails webpacker:install
