Help please

You're using the pip command included with your Python3 installation (3.7), but the package is for Python 2.

Have you solved it？
i tried python2 -m install unicorn-1.0.1.tar.gz.
This error occurs.

[aquynh]

You can install the 1.0.2-rc1 version with: pip install --pre unicorn

[Lv9S]

thank you.
i tried pip install --pre unicorn.
it has resolved.

You can install the 1.0.2-rc1 version with: pip install --pre unicorn

Hi, the method seems not work on macOS

@rhelmot do you have any comments?

[rhelmot]

this is a different bug and should have been a different issue but it is an issue. I will push a fix. In the meantime you may work around it by removing msbuild from your PATH.

[Arusekk]

As of 2020, many distros have default python executable set to python 3.x, while the qemu bundled in 1.0.1 requires python 2 to build, rendering the stable version on PyPI virtually useless.

I would suggest cutting a new release, even from unstable source, but I know that it would influence not only PyPI, but also other package repositories. Do you know of any solutions to this?

[rhelmot]

I think pending the current stuff about the python bulld on macos, 1.0.2 should be able to release soon in a pretty stable condition, judging from the recent commit activity.

[aquynh]

I can tag 1.0.2-rc2 for this issue.

[rhelmot]

can we please just release 1.0.2 as soon as the mac stuff is resolved? it's been two and a half years since 1.0.1. I have to tell people to install with --pre in order to resolve problems so often and I am so tired :(

[aquynh]

we are still fixing OSS fuzz bugs. i want to have all cleared before 1.0.2 release.

[rhelmot]

Can we do the rc2 release now?

[aquynh]

yes, i tagged rc2, please update Pypi package, thanks!
