php Composer was working fine and then I updated and now I get this message with nothing else changed. Notice the 2nd backslash in https:\ is missing.
Failed: [Composer\Downloader\TransportException] 0: The "https:\xxx.xxxxxx.com/repos/release-belt/releases/Key-Words-1.00.zip" file could not be downloaded: failed to open stream: No such file or directory
the packages.json file did not change and has https:\xxx.xxxxx.com. I'm using Slim to handle the download on the server
