Error Modules & Dependencies production

Bug Report

Hi everybody, After many attempts, I still get the error that I report below, I have done it with the npm run build command and also with webpack, but it has not worked in any way when I want to pass my project to production.

Apparently it is not loading any module in production.

I really appreciate the help you can give me.

Thanks…

Current behavior

After run ‘node main.js’ in the terminal open this error:

Error: Cannot find module ‘@nestjs/core’ Require stack:

• C:\server\main.js  at Function.Module._resolveFilename (internal/modules/cjs/loader.js:982:15)  at Function.Module._load (internal/modules/cjs/loader.js:864:27)  at Module.require (internal/modules/cjs/loader.js:1044:19)  at require (internal/modules/cjs/helpers.js:77:18) at Object.<anonymous> (C:\server\main.js:118:18) at webpack_require (C:\server\main.js:20:30) at Object.<anonymous> (C:\server\main.js:103:16) at webpack_require (C:\server\main.js:20:30) at C:\server\main.js:84:18 at Object.<anonymous> (C:\server\main.js:87:10) { code: ’MODULE_NOT_FOUND’, requireStack: [ ’C:\server\main.js’ ] }

Just like with any other node server, you still need your production dependencies. You need the package.json, the dist and the node_modules so that node knows how they’re all related to each other. This is the standard approach and not specific to Nest. Please use our Discord for further discussion.

@mohsinamjad that’s not really the case for node servers, yes you can use webpack for some of that, but it can’t work with everything, as mentioned in the linked answer, due to requiring underlying lower level processes that could vary from machine to machine (bcrypt and database drivers are two common examples). Because of this, you can webpack it all into a main, but you still need to install the dependencies for production.
