I tried to enable curl on cygwin but it says bash: curl: command not found
How do I install curl on cygwin?
In order to use the command-line version of curl, you need the curl executable. So, run the Cygwins Setup.exe, and select curl (under Net->curl). That one uses libcurl3, which is located in Libs->libcurl3. But libcurl3 will be pulled in as a dependency if it's not already installed. So, just select Net->curl and you're good to go.
