Build Error: Non-Zero Exit from node_modules file.

I am getting a build error when attempting to run a script from a dependency to build my website.

$ node ace build
Debugger attached.

TypeError: commandInstance.exec is not a function


1 Kernel.execMain
  /Users/craigsau/Documents/Programming Stuff/PersonalSite/node_modules/@adonisjs/core/node_modules/@adonisjs/ace/build/src/Kernel/index.js:201

2 Kernel.handle
  /Users/craigsau/Documents/Programming Stuff/PersonalSite/node_modules/@adonisjs/core/node_modules/@adonisjs/ace/build/src/Kernel/index.js:528

3 App.handle
  /Users/craigsau/Documents/Programming Stuff/PersonalSite/node_modules/@adonisjs/core/build/src/Ignitor/Ace/App/index.js:226

4 Ace.handle
  /Users/craigsau/Documents/Programming Stuff/PersonalSite/node_modules/@adonisjs/core/build/src/Ignitor/Ace/index.js:33

However, this error is fixed by changing commandInstance.exec(); to commandInstance.exec; and runs successfully locally after making the change.

The problem lies that this is in node_modules, which is a gitignored file, and I believe it should stay that way. Is there any way to fix this without unignoring the node_modules?

Hello,

It sounds like it might be due to incompatible Node.js version.

What version of Adonis.js are you using? Based on that, I could suggest trying to use the supported Node.js version.

Then you can specify the Node.js version in your package.json file as follows:

{ 
  "engines" : { 
    "node" : "16.0.0" 
  }
}

Make sure to change the "16.0.0" version accordingly.

Let me know how it goes!

Best,

Bobby
