Os.homedir is not a function

#1

I just updated my ionic project to latest version, now when I want to start it (browser) it only shows the error in the browser:

"os.homedir is not a function"

The line it complains is:

exports.CONFIG_DIRECTORY = path.resolve(os.homedir(), '.ionic');

Any ideas?

ionic info

global packages:

@ionic/cli-utils : 1.4.0
Cordova CLI      : 7.0.1
Ionic CLI        : 3.4.0

local packages:

@ionic/app-scripts              : 1.3.7
@ionic/cli-plugin-cordova       : 1.0.0
@ionic/cli-plugin-ionic-angular : 1.0.0
Ionic Framework                 : ionic-angular 3.5.0

System:

OS         : Windows 10
Xcode      : not installed
ios-deploy : not installed
ios-sim    : not installed
npm        : 4.2.0

edit:
Adding “console.log(os)” in front of this line, results in:
-> Webstorm console shows an printed object WITH “homedir” function.
-> Browser console shows an printed object WITHOUT “homedir” function.

Not sure where these should be coming from…

edit2:
Seems like it should be coming from “os-homedir” npm package, which is actually there. Maybe webpack throws it out?
Stacktrace is:

Uncaught TypeError: os.homedir is not a function

edit3:
I tried fixing it by adding the code from os-homedir package into browser.js from os-browserify package, but that threw up new errors because homedir() is returning NULL. Having a deeper look it seems like this is nodeJS code which should never be called in browser at all?

Solved it… My mistake.
I (Webstorm?) accidently imported “Exception” from cli-utils module, which forced webpack to include it into the build. Since the mentioned code is executed during setup of this package, it throws that error.

Replacing that line by the correct import solved it:
import {Exception} from "@ionic/cli-utils";
