Compile issue (error[E0658])
darrida opened this issue · comments
Hi there. I heard about this on PythonBytes the other day. Really enjoy the times they've had you on either that or Talk Python.
This tool sounds great. When working on Windows I have a batch script on my path that allows me to use pyv to create an environment, upgrade pip, install from requirements (or setup.py if it exists). I've really wanted something that would at least quickly activate an environment when using something like WSL, but never got around to looking into it.
I'm attempting to install this in Ubuntu-20.04 WSL2 (on Windows 10 Pro 19042.804). I've only used cargo a couple of times, but had just installed it fresh this time. Looks like cargo version 1.46.0.
Any thoughts?
(btw - thanks so much for all you do)

You're using an old version of Rust. Upgrade to Rust 1.50.0 and it will compile fine.
And thanks for the compliment!
Worked perfect. Thanks for the help.
