I upgrade my webpart project to spfx RC0. When I build the webpart I get and error in node_modules\@types\webpack-env\index.d.ts(186,13) shown below. I’m not sure what is causing it.
I delete the webpack-env folder from my node_modules and, although I get some warnings at build time, the webpart does build and run fine
So my question is what is causing the errors shown? Is it safe to just delete webpack-env from my package.json and leave it at that?
