Please give this another shot @Ansen04 ; #658 was just merged

tom10271 commented 4 years ago

@s1113950 Do you think the fixing contains in 0.2.9? I have python3 installed on my VPS but facing a similar error

s1113950 commented 4 years ago

The fix is not in 0.2.9 @tom10271 . There will be 1 or 2 Mitogen versions released very soon once https://github.com/dw/mitogen/pull/715 lands though, which will contain the fix. In the meantime, you can do what you noted here: https://github.com/dw/mitogen/pull/658#issuecomment-724609344 and get the fix :)
