Error: An accessor cannot be declared in an ambient context

Bug

What is the current behavior?

When building a project with a Typescript version less than 3.7, build fails with an error

ERROR in ../node_modules/@oclif/command/lib/command.d.ts:48:9 - error TS1086: An accessor cannot be declared in an ambient context.

48     get ctor(): typeof Command;
           ~~~~

error Command failed with exit code 1.

This appears to be happening since v1.6.0 (Breaking change introduced in #85). Previous version of oclif v1.5 does not have this issue (as typescript is an earlier version).

What is the expected behavior?

Build should succeed. I'm not sure if typescript can be downgraded, or at least a Breaking Change be noted in the changelog, etc.

I tried to recreate this in a freshly-generated OCLIF project with TypeScript 3.6.4 but didn’t encounter the error. Could you provide more context from your project? The tsconfig.json may be useful to help us narrow down the issue. Thanks!

Hey @jgwhite, my tsconfig.json is the default one from a freshly-generated project. I have since tried to reproduce the bug i was having in may, with no luck. I believe my yarn/npm cache was just out of sorts. thanks!

@yatryan great to hear it’s working! Thanks for the response.
