Ruby on Rails 6 无法使用 webpack 部署到 heroku
Ruby on Rails 6 can't deploy to heroku with webpack
我将我的应用程序升级到 RoR 6,其中包括使用 webpack。我以前使用的是 React-Rails,资产管道中的组件,但现在我的文件结构如下所示:
app
assets
controllers
javascript
components
packs
application.js
src
config
webpack
development.js
environment.js
production.js
etc...
在开发中一切正常,但是当我尝试推送到 heroku 时,几天来一直是个问题。我已经尝试了所有可以在网上找到的东西,我只需要一些新鲜的眼光。
目前,构建失败并显示 Can't resolve './src' in '/tmp/build_70fb951d'
。我在网上找到的所有内容都建议在配置文件中添加一个 entry
,指向 javascript/packs/application.js
,但它似乎并没有改变错误。

这是最浪费时间的事情,我会删除这个问题,但希望这个答案能帮助其他人节省时间。
解决方案是添加一个名为 src
的文件夹,并在该文件夹中添加一个名为 index.js
的空文件
下面是我的文件结构示例:
app
bin
config
db
src
index.js
lib
index.js
是空的,除了一个小注释:
//This file solves a bug deploying to heroku. Do not delete
This post and this post 帮我找到了这个解决方案。
一旦我开始工作,我已经移动和更改了很多东西,我需要重新运行 bundle exec rails webpacker:install
因为现在我收到这个错误:
Webpacker can't find application in <my app path>/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:
{
}
This post helped me solve that.
现在一切正常!
如果您使用的是 Webpacker 5,则部署的 ruby 步骤需要 webpack-cli
已安装,因此 webpack
二进制文件可用。首先检查您安装的构建包,特别是它们的 order
heroku buildpacks --remote staging
=== beamstage Buildpack URLs
1. heroku/ruby
2. heroku/nodejs
如果 heroku/ruby
出现在 heroku/nodejs
之前,那么您需要交换它们,因为构建包的顺序确实决定了依赖项的安装顺序。 Ruby 首先表示 bundle install
以及 rake assets:precompile
在 yarn
之前。我能找到交换的唯一方法是将它们都删除然后再次添加:
heroku buildpacks:remove heroku/nodejs [--remote <staging|production>]
heroku buildpacks:remove heroku/ruby [--remote <staging|production>]
heroku buildpacks:add --index 1 heroku/nodejs --remote staging
heroku buildpacks:add --index 2 heroku/ruby --remote staging
