Answer that worked for me (W10/Ruby2.6.0) was:
- Download cURL from the following URL: https://curl.haxx.se/windows/ (I chose 64bit because that’s the system I’m using)
- Go into the archive and browse to
/bin
- Locate
libcurl_x64.dll
(it may be justlibcurl.dll
) - Extract to your local drive
- Rename it to
libcurl.dll
if it has the_x64
suffix - Cut + paste the file into the
/bin
directory of your Ruby installation
