not compatible with latest rust 1.72.0 about evcxr HOT 8 OPEN

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?

from evcxr.

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?

from evcxr.

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

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.

from evcxr.

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.

from evcxr.

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

from evcxr.

Finally I installed the nightly toolchain, then evcxr can work.
(py311) [wangjw@localhost src]$ rustup toolchain list

(py311) [wangjw@localhost src]$ rustup toolchain install nightly
