npm run build / deploy error on windows

Question

I am trying to compile files with webpack and npm for my reactJS applciation.

When I run npm start, it all goes well. When I run npm run deploy or npm run build it does not work under a windows environment. It does work under a linux environment.

Does someone have an idea why ?

My files :

Answer 1

It looks like the configuration file is not 100% correct. See details below:

• need to import 'webpack' mobile before using it (webpack.config.js), i.e., const webpack = require('webpack');

• need to import path module before using it (webpack.config.js), i.e., const path = require('path');

• devFlagPlugin is not defined

• also exclude the node_modules directory in the loader

  module: {
      loaders: [
          {
              ....
              exclude: path.resolve(__dirname, 'node_modules/')
          }
      ]
  }
  

Answer 2

You can set environment variables in a cross-platform manner by using cross-env:

"deploy": "cross-env NODE_ENV=production webpack -p --config webpack.production.config.js"

Answer 3

I think you have two different problems.

Lodash is missing?

Now, I'm not an expert in Webpack so somebody may point out something obvious that I don't see...but...when you say it doesn't work under Windows, have you tried it on multiple Windows systems?

If this issue is only on one system or it's a PITA to get onto a second box or whatever, try:

1. Delete the node_modules directory
2. Execute npm cache clean to be sure you'll start fresh when you reinstall
3. Re-install with npm i --verbose > npm-install-log.txt

If the install still doesn't work, you'll have an install log to review to see if something is failing to compile or there's some other wacky error that may not be visible after install.

NODE_ENV on Windows

The NODE_ENV=production <commands> syntax is a *nix thing but not a Windows/DOS thing.

In this case, you may find it easier to create a .bat file for this where you set the variable on the first line and call the command on the second. However, this won't work on *nix platforms so....maybe:

1. Create two scripts and two entries in package.json, one for each OS. If it's a simple project that's mostly maintained by hand, that's probably cool.
2. Create a deploy.js script, executed by node, that sets the NODE_ENV variable, calls webpack via the node api to do the work. This should be OS independent and is a single script...
