Hi Guys, I have version 1 installed on my PC but I want to install cwltool implementation in compliance with draft 3 standards. What is the convenient way to install the older version of CWL? Thanks

Hello farahk,

The current version of CWL aims to support all draft-2, draft-3, and v1.0 compliant CWL documents.

You can test older versions like so: pip install cwltool==1.0.20150317015350

To get a list of all older versions of cwltool try pip install cwltool==invalidversion.

Hopefully we can get this fixed for you soon.

Try this link:

This is a short description:

This is what github provides:

Hi Natasha, Thanks for your reply. My question is I guess a bit vague. Let me put it in different way.

Is there any way to install an older version of cwltool instead of the latest version installed when the directions from the github are followed?

Thanks
