我正在学习如何在 Racket 中编程。它的二进制文件位于"/Applications/Racket v6.2/bin/racket"
.
让我展示一下会发生什么:
MacBook:~ enedil$ echo $PATH
/Applications/Racket\ v6.2/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin
MacBook:~ enedil$ ls -l /Applications/Racket\ v6.2/bin/racket
-rwxr-xr-x@ 1 enedil admin 53712 Jun 19 22:23 /Applications/Racket v6.2/bin/racket
MacBook:~ enedil$ file /Applications/Racket\ v6.2/bin/racket
/Applications/Racket v6.2/bin/racket: Mach-O 64-bit executable x86_64
MacBook:~ enedil$ racket
-bash: racket: command not found
MacBook:~ enedil$ bash --version
GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin14)

这怎么可能呢?如果我想要一个完全工作的 Racket 编译器在我的路径中该怎么办?

看来您在编辑PATH
变量时犯了一个错误。输出中的反斜杠字符PATH
被视为文字,而不是转义空格。
你需要:
PATH="/Applications/Racket v6.2/bin:$PATH"; export PATH
或者:
PATH=/Applications/Racket\ v6.2/bin:$PATH; export PATH
