Cannot read property 'onDidChangeIcon' of undefined (Failed to activate the file-icons package)

UPDATE 2017/12: If you’re seeing this error after installing the package, please restart Atom. Everything will then work as expected.

This is a known and temporary issue. See below.

Atom Version: 1.15.0 x64 System: Microsoft Windows 10 (10.0.14393 Build 14393) Thrown From: file-icons package, v2.1.1

@totovr Did you deactivate and reactivate any of the following packages…?

• file-icons
• tree-view
• tabs
• fuzzy-finder
• find-and-replace
• archive-view

If so, I’m afraid that requires a restart as well. Sorry.

Technically, the issue isn’t with installing, but changes in the package’s activation status. It’ll be fixed in the next release of Atom. 😃

Same here, but just happens on a new install and on disable/enable. If you enable it and restart atom the icons show up and no warning shows up.
