TypeScript errors during grunt

Question

TypeScript errors during grunt

Closed this issue 7 years ago · 2 comments

Hello -- I cloned the repo from master (currently at b502383), ran npm install and grunt then got the following errors. (I am new to TypeScript so I wouldn't be surprised if this is an easy issue.)

OS: OSX 10.11.6 (dev laptop is a mac, this is going to be built to run on my Windows PC though)
node: v6.11.0
grunt-cli: v1.2.0
grunt: v1.0.1

Thanks for letting me know! I just updated to the latest versions of all dependencies and fixed my code to match. Grab my new code, clean out your node_modules directory and re-run npm install. Then you should be able to run grunt without errors. Let me know if that works and I'll close this issue.

Answer 2 · 2017-07-20T05:11:19.000Z

That appears to be working now - thanks!
