error TS2554: Expected 0-1 arguments, but got 2. about ember-cli-typescript

[dwickern]

Are you using the latest typings from @types/ember?

[danielgratzl]

Yes, I used the setup described in the README.md and my package.json shows

"@types/ember": "^2.8.2",
"@types/ember-testing-helpers": "0.0.3",
"@types/rsvp": "^4.0.0",
"ember-cli-typescript": "^1.0.5",
"jquery": ">= 1.7.0 < 4.0.0",
"typescript": "^2.6.2",

Huh. I have a fair number of mixing applied this way, but I think they’re all in controllers and routes, so I’ll test locally and see if I can reproduce e sometime today.

[danielgratzl]

@chriskrycho Have you been able to reproduce the behaviour?

[chriskrycho]

Apologies, but no: had another issue come up at work. I should be able to dig in either tomorrow or Monday, though.

[chriskrycho]

@danielgratzl so I just built this out myself and… I can't reproduce. 😬

A suggestion which may fix it:

• Change all the @types/ values for the Ember-related types in your package.json to "*" instead of a specific version
• Do yarn upgrade @types/ember @types/rsvp @types/ember-testing-helpers (or equivalent npm invocation)
  • for good measure, after doing so you might also rm -rf node_modules and then yarn or npm install again

Then let me know what you see. 🤔

[chriskrycho]

@danielgratzl can you confirm this is still a problem for you after trying the above? If not, I'll close this issue; trying to keep issue count meaningful.

[chriskrycho]

I’m closing this as I can’t reproduce it and haven’t gotten any further info on how to do so. Please feel free to reopen if there’s more info to share!
