OSX自制Lua51找不到lua命令

Question

当我用brew安装lua51时，它无法运行该命令。但是，当我只安装lua (默认情况下安装了Lua5.2)时，lua命令就能工作了。

我试过brew链接，但这表明lua51已经链接了。

这是一份笔录

Answer 1

我下载了https://homebrew.bintray.com/bottles/lua@5.1-5.1.5_4.el_capitan.bottle.tar.gz并看到它包含

./5.1.5_4/bin/lua-5.1
./5.1.5_4/bin/lua5.1 -> lua-5.1

因此，您需要运行lua-5.1或lua5.1，而不是普通的lua。
