I get an error: The sourceMapTarget option has been removed ...

[scharf]

I get the following error and I am not sure how to fix it and if it really has to do with nathantreid:typescript-babel:

While processing files with nathantreid:typescript-babel (for target os.osx.x86_64):

   /Users/scharf/.meteor/packages/meteor-tool/.1.6.1_1.162ni0e.31l7++os.osx.x86_64+web.browser+web.cordova/mt-os.osx.x86_64/dev_bundle/lib/node_modules/@babel/core/lib/config/validation/options.js:95:11:
   Using removed Babel 6 option: .sourceMapTarget - The `sourceMapTarget` option has been removed because it makes more sense for the tooling
   that calls Babel to assign `map.file` themselves.

My guess is that the problem is here

See also the meteor/babel-compiler

[scharf]

see babel/babel#7500

I am using meteor 1.6.1, I think they have upgraded babel and fixed the problem for this version...

[scharf]

I really think, meteor should maintain typescript support

This issue was fixed some time ago, but I forgot to close it. Thanks for the report!
