我从官方网站安装了 DrRacket，它为我创建了一个可执行文件名为 gracket 的文件（在 bin 内），我认为它是 DrRacket 的 GUI 版本，但是当我执行它时它什么也不做。（它说了一些关于缺少文件的信息：libjpeg.so.62和libpng.so）
我怎样才能让它运行？
Lubuntu 16.10 DrRacket 1.5.3
代码：
poo@poo-1015PE:~/racket/bin$ ls
drracket mred-text mztext plt-help racket slatex
gracket mzc pdf-slatex plt-r5rs raco slideshow
gracket-text mzpp planet plt-r6rs scribble swindle
mred mzscheme plt-games plt-web-server setup-plt tex2page
poo@poo-1015PE:~/racket/bin$ ./gracket

答案1
缺少的库文件libpng.so和libjpeg.so.62是两个包libpng-dev和的一部分libjpeg62。您应该能够通过运行来安装它们
sudo apt install libpng-dev libjpeg62
