tsoa routes command not working anymore

[AmirMaurice]

Today, I cloned a repo that is using tsoa. While running tsoa routes I came across the following errors:

(node:2836) UnhandledPromiseRejectionWarning: TypeError: ts.formatting.RulesProvider is not a constructor

First I thought it is related to MacOS because it is working for me on another Linux machine (i.e. Ubuntu). After digging into the errors a little bit, it seems to me that it is because of the latest version of TypeScript 2.7.1 which was released yesterday: In this release they removed the RulesProvider class completely from the typescript.js.
Can anyone comment?

@AmirMaurice I am having the same problem on Windows (just because you were thinking it might be related).
I can also confirm having found the issue of the missing/moved RulesProvider class inside the main typescript.js. However I think this issue rather belongs to the typescript-formatter project.

I spent almost 8 hours, up till now, not work, dont know why!

My quick fix is to fork & build tsoa with latest Typescript 2.7.1 & formatter.
If anyone need that fix while waiting for official release from tsoa, please refer to my git package by running following 2 commands at your node module:
npm uninstall tsoa
npm install thanhptr/tsoa

Thanks all, let me look into getting things updated to 2.7.1 ASAP.

Good to see, I'm not the only one with that problem. For now i solved it by using TypeScript 2.6.2.

Any updates when it will be fixed?

[egandro]

Any Progress? Do you guys need help?

[egandro]

I fixed it.

https://github.com/lukeautry/tsoa/pull/191

• typescript-formatter updated to 7.0.1
• some small parameter fixes internal typescript methods.

A test is broken (please fix this).

@lukeautry can you please push this to npm asap?

Thx.

Issue should be fixed in 2.1.0 - please let me know if you're still having trouble.
