CocoaPods Environment

pod env produces the same error.

Project that demonstrates the issue

You don't need a special project but you _do_ need a Windows environment from which to run this.

I'm including the following because I don't know what is relevant.

Not sure here the issue. Sorry I dont have a windows machine to diagnose. Would appreciate help to diagnose this.

Getting the same problem. Not sure what to do.

1. Download curl from https://curl.haxx.se/windows/
2. Extract the archive and browse into /bin
3. Rename libcurl_x64.dll (it may be just libcurl.dll for x86) to libcurl.dll
4. Copy and paste the file into the /bin directory of your Ruby installation folder
5. Happy coding!
