Cannot resolve module 'xhr2'

[fskinner]

I'm getting this error everytime i run my webpack bundle. I've installed reqwest via npm

Module not found: Error: Cannot resolve module 'xhr2' in c:\Users\xxx\Git\xxx\node_modules\reqwest

[ded]

are you intending to use this in Node.js or the Browser?

[ded]

One solution is to simply install xhr2 — it's noted a peerDependency (meaning, you have to install it yourself). That is, if you're using it in Node.js.

Otherwise, I'm not entirely clear how WebPack Bundles libraries. I could add a try {} catch () to mitigate the issue. The fact of the matter is xhr2 is not an actual dependency if you're running it in the browser, so it's best left out as a real dependency in the package.json file

[fskinner]

I'm using on the browser. I will add it on my dependencies then! But it would be better not to depend on it, since I'm on the browser... And not showing that annoying warning :(

[ded]

yes indeed. i will get a fix out for this shortly

[veddermatic]

Seconding this. While reqwest works fine in-browser with the warning, it will save many a moment of panic to handle it better.

+1

[ded]

hey all! this has been resolved thanks to a workaround found in a recent pull-request. you should be good to go now. it will no longer blow up in the browser

[fskinner]

great to hear!

2.0.3 broke my build, webpack output below. I reverted to 1.1.6 to get rid of the xhr2 message, haven't had any problems with it yet.

[serslon]

I have the same problem occurred. I fix it only to downgrade to 2.0.1

[christla]

Yep, having the same issue

[dopeboy]

+1. I reverted to 1.1.5 to fix this problem.

[ded]

well damn. will need to think another solution. this was exactly my reservations to begin with (trying to make this library "isomorphic").

in the meantime looks like a few folks were able to successfully revert.

[t1mmen]

2.0.2 and 2.0.4 both broke my build, reverting to 2.0.1 fixed it. My errors, to help those coming via search engines:
