Re: [Minios-devel] [UNIKRAFT PATCH v2 7/8] support/scripts: make uk-trace installable

[Yuri Volchkov <yuri.volchkov@xxxxxxxxx>]

Hi Costin,

thanks for testing this. I think I fixed your problems. Before I send
v3, could you please try again with the attached patch?

Please note, that documentation is changed tool. Now creating of virtual
environment is done using 'virtualenv' tool. Which installs 'wheel'
package - that should solve your second problem.

Thank you!
Cheers, Yuri.
