是否可以降级使用ELPA安装的软件包? [英] Is it possible to downgrade packages installed with ELPA?
问题描述
可变绑定深度超过max- specpdl-size
错误。
由于调试不容易,是否可以降级更新的包?我在哪里可以找到一个ELPA日志,在那里我可以获得这些软件包的以前版本?
code>(setq debug-on-error t)在〜/ .emacs
文件的早期。您还可以使用 emacs --debug-init
获得类似的结果。这就是说,有时你在这里遇到的错误也可以防止调试器出现。我建议您 Mx report-emacs-bug
并描述问题,以及您发现的任何其他信息,包括您找到的解决方案(如果有的话)。
对于降级包,技术上是可行的,但没有UI支持。并且还没有安装软件包日志。请在错误报告中提及这一点,因为尝试跟踪这些事情确实是一个好主意。
对不起,
I updated today my packages in emacs with ELPA and after the update I'm stuck with the
Variable binding depth exceeds max-specpdl-size
error. Since it is not easy to debug, is it possible to downgrade the packages that were updated? Where can I find an ELPA log where I can get the previous version of these packages?
I second @lawlist's recommendation to (setq debug-on-error t)
early in your ~/.emacs
file. You can also use emacs --debug-init
to get a similar result. This said, sometimes the kind of error you get here can also prevent the debugger from showing up. I recommend you M-x report-emacs-bug
and describe the problem, along with any additional info you find, including the solution you found, if any.
As for downgrading a package, it's technically possible, but there is no UI support for it. And there's no log of package installs either. Please do mention this in the bug-report as well, since it's indeed a good idea to try and keep track of those things.
Sorry.
