当我尝试drracket在 Ubuntu 12.04 上使用时，出现此错误：
ffi-lib: couldn't open "libjpeg.so.62" (libjpeg.so.62: cannot open shared object file: No such file or directory)

我该如何纠正这个错误？
答案1
请尝试
sudo apt-get install libjpeg62
并重新运行该程序。
顺便说一句，我无法重现这个错误！
答案2
如果重新安装不能解决此错误，请尝试：
locate -i libjpeg
这将搜索库的所有实例，以便您可以使用正确的路径编辑必要的文件。
