To not error.

It looks like TypeScript only just recently added wildcard support to ambient module declaration in June to TypeScript 2.0.0. See TypeScript Issue#6615.

Also relevant from their What's New In TypeScript 2.0 wiki entry:

WildChard module names can be even more useful when migrating from an un-typed code base. Combined with Shorthand ambient module declarations, a set of modules can be easily declared as any.

Example

declare module "myLibrary/*";

Should be fairly straightforward to check for this new syntax and not visit the non-existent module block in OneLineWalker if anyone wants to send a bugfix PR.

[macklinu]

Was this resolved by #1429 and can be closed?

[nchutchind]

@macklinu the changes in the commit from #1429 do, indeed, resolve this issue.

[michaeljota]

Did this get any release? I'm having this bug in 3.15.1

[arlair]

I am getting similar with Webstorm trying to declare a module:

declare module "test";

INFO - avascript.linter.tslint.TsLint - TsLint inner error. TsLint version: 3.15.1

TypeError: Cannot read property 'kind' of undefined

[arlair]

Oh, looks like this might be coming in Version 4.
"The changes in #1429 will be available in the next TSLint release, which will be 4.0"

[michaeljota]

Thanks @arlair I did not see that issue.

[michael-brade]

What is the reason that a line like

/* tslint:disable */
declare module "test";

before the declare module doesn't work? I am in a situation where this would be the only solution until 4.0 is released, but I'm having no luck.

[adidahiya]

hey folks, sorry for the pain around this bug. I'll cut a new release on the next branch which you can depend on to get the latest TSLint fixes.

[jonaskello]

Having the same problem and // tslint:disable-next-line does not work either.

[adidahiya]

v4.0.0-dev.0 is available now (npm install tslint@next), can you try that?

[jonaskello]

@adidahiya Yes that works!

[michaeljota]

Work! Thanks! :)

[Andrey-Pavlov]

npm install tslint@next helps me
