not compatible with latest rust 1.72.0

[wangjiawen2013]

Hi, The latest rust version is 1.72.0, but it seems that the latest evcxr don't compatible with rust 1.72.0. I fall back to rust 1.68.0, then evcxr worked well.

It works fine for me on 1.72.0, so I might need some help to reproduce. How are you switching rust versions? I assume you're switching version before you launch evcxr? Switching while evcxr is running isn't supported and could lead to surprising results. Does it crash consistently on 1.72.0 or only sometimes?

[wangjiawen2013]

Yes, it crash consistently on 1.72.0, I tried several times. Then I downgrading rustc to 1.68.0 using "rustup default 1.68.0" and reinstalled evcxr again. Here's the full error:

What operating system (including version) are you using?

[wangjiawen2013]

LSB Version: :core-4.1-amd64:core-4.1-noarch Distributor ID: CentOS Description: CentOS Linux release 7.9.2009 (Core) Release: 7.9.2009 Codename: Core

[SichangHe]

Similar error with:

Linux 3.10.0-957.el7.x86_64 #1 SMP GNU/Linux
rustc 1.73.0 (cc66ad468 2023-10-03)

It does not just crash by typing :help, it crashes when running a large chunk of code. The dependencies compiled fine, but then it crashed.

Rolling back to 1.71.1 did not help. But, anyway, I think I would give up on the public server I was testing it on because it was too buggy.

[davidlattimore]

I tried installing CentOS 7.9.2009 (in virtualbox) then installing evcxr in it... it worked for me. So I'm not sure what's needed to reproduce this.

[wangjiawen2013]

It cannot work on the latest rust 1.74 too, the same error occured.

[wangjiawen2013]

Finally I installed the nightly toolchain, then evcxr can work. (py311) [wangjw@localhost src]$ rustup toolchain list stable-x86_64-unknown-linux-gnu (default) (py311) [wangjw@localhost src]$ rustup toolchain install nightly (py311) [wangjw@localhost src]$ rustup default nightly
