升级DrRacket8.10到8.18版本

安装参考：在FreeBSD、Windows、Ubuntu24三种平台下安装Racket多范式编程语言_racket安装-CSDN博客

Ubuntu24.04里面的版本是8.10,所以无法使用apt upgrade升级，最终是使用下载升级软件，手工升级完成！

首先尝试直接在软件里升级，升级失败

网站提示的升级方法

Running the Linux installer:

After downloading the installer file, run it with

    sh racket-8.18-x86_64-linux-buster-cs.sh

to install, possibly adding sudo to the start of the command to install to a location that requires administrator access.

When upgrading:

To restore packages installed for a previous version of Racket, use DrRacket's File > Package Manager > Copy from Version or at a command line use raco pkg migrate.

下载软件

官网很慢，所以到到清华源下载8.18版本：Index of /installers

下载后执行

sudo sh racket-8.18-x86_64-linux-buster-cs.sh

执行交互很复杂：

sudo sh racket-8.18-x86_64-linux-buster-cs.sh

This program will extract and install Racket v8.18.Note: the required diskspace for this installation is 691M.Do you want a Unix-style distribution?In this distribution mode files go into different directories accordingto Unix conventions.  A "racket-uninstall" script will be generatedto be used when you want to remove the installation.  If you say 'no',the whole Racket directory is kept in a single installation directory(movable and erasable), possibly with external links into it -- this isoften more convenient, especially if you want to install multipleversions or keep it in your home directory.

说实话，这个交互，真的很繁琐！

升级安装完成！

启动DrRacket

调试

升级后drracket启动报错

执行

sudo raco setup

搞定！
