[英]webpacker not working correctly on heroku
I'm in the middle of upgrading an app from rails 3.2 to rails 4.2 using webpacker gem everything works fine in localhost I have compiled my assets and run 我正在使用webpacker gem将应用程序从Rails 3.2升级到Rails 4.2,在本地主机上一切正常,我已经编译了资产并运行
RAILS_ENV=production rails s RAILS_ENV =生产导轨
but I have errors when pushing to heroku it compiles all assets even the packs but generates errors in js, I use angular in many parts of the app and the error is related with dependency injection 但是当推送到heroku时我出错,它编译所有资源,甚至是包,但是在js中生成错误,我在应用程序的许多部分中使用angular,并且该错误与依赖项注入有关
The main problem here was the unglifier gem I had to coment the uglifier 这里的主要问题是我必须对丑化器进行注释的未发育成宝石的宝石
#config.assets.js_compressor = :uglifier
The next part was the configuration for webpack in production that look like this: 下一部分是生产中Webpack的配置,如下所示:
const webpack = require('webpack')
const { basename, dirname, join, relative, resolve } = require('path')
const merge = require('webpack-merge')
const CompressionPlugin = require('compression-webpack-plugin')
const sharedConfig = require('./shared.js')
const { env, settings, output, loadersDir } = require('./configuration.js')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
const ManifestPlugin = require('webpack-manifest-plugin')
module.exports = merge(sharedConfig, {
output: { filename: '[name]-[chunkhash].js' },
devtool: false,//'source-map',
stats: 'normal',
plugins: [
new webpack.EnvironmentPlugin(JSON.parse(JSON.stringify(env))),
new ExtractTextPlugin({
filename: '[name]-[hash].css',
allChunks: true
}),
new ManifestPlugin({
publicPath: output.publicPath,
writeToFileEmit: true
})
],
resolve: {
extensions: settings.extensions,
modules: [
resolve(settings.source_path),
'node_modules'
],
alias: {
'vue$': 'vue/dist/vue.esm.js' // 'vue/dist/vue.common.js' for webpack 1
}
},
resolveLoader: {
modules: ['node_modules']
}
})
Now I can deploy and the assets are working. 现在我可以部署并且资产正在运行。
