error: Error: webpack failed! [code 1]

I cannot find any recent issue or Stackoverflow page for this error with given version.

Could you please help?

I had this issue and solved it by explicitly installing monaco-editor and monaco-editor-webpack-plugin from npm alongside vue-monaco in my project.

My package.json:

"dependencies": {
    // ...
    "monaco-editor": "^0.20.0",
    "vue-monaco": "^1.1.0"
},
"devDependencies": {
    // ...
    "monaco-editor-webpack-plugin": "^1.7.0"
},

so just try:

yarn add -D monaco-editor-webpack-plugin
yarn add monaco-editor

or its npm equivalent

I have the error as well.

• OS: Windows 10.

I tried:

git clone https://github.com/reactide/reactide.git
git checkout 3.0-release
npm install
npm run webpack-production

and the error occurs, so I try:

npm install monaco-editor monaco-editor-webpack-plugin 
npm run webpack-production

but that didn’t help, so I try:

npm install vue-monaco
npm run webpack-production

“A complete log of this run”: https://pastebin.com/KiLJyy7y

…still no success, so tried “alongside vue-monaco” @cavatron don’t really know what that means, please explain. I tried:

cd node_modules/vue-monaco
npm install monaco-editor monaco-editor-webpack-plugin 
cd ..\..
npm run webpack-production

@cavatron I tried mimicking your package.json:

• changed "monaco-editor": "^0.14.3", to "monaco-editor": "^0.20.0",

• ran npm install

• ran npm run webpack-production

• ran npm run webpack-production

• got more errors:

  • Module not found: Error: Can't resolve 'spawn-sync' in 'C:\PortableApps\reactide\node_modules\execa\node_modules\cross-spawn'
  • See full output: https://pastebin.com/u9F2m9MY
    • “A complete log of this run”: https://pastebin.com/rdAFEuKe

not tried yet

• change "monaco-editor-webpack-plugin": "^1.9.1", to "monaco-editor-webpack-plugin": "^1.7.0",
• npm install again

@cavatron or someone, should that upgrade and downgrade the two packages respectively? Is there any point in that now, and should I post this somewhere else at this point?
