如何更改已安装的 Lua 版本（Windows 10）

Question

试图掌握 LuaDist。

按照https://github.com/LuaDist/Repository/wiki/LuaDist%3A-Installation 的说明进行操作，并通过使用以下方式构建新部署来测试安装：

cd _install\bin
luadist C:\my_lua install lua luasocket md5
cd C:\my_lua\bin
lua -e "require 'md5'"

但是我收到以下错误消息：

Finding out available versions of lua...
Getting lua-5.3.2 (source)...
Finding out available versions of luasocket...
Getting luasocket-3.0-rc1 (source)...
 - trying another candidate due to: Error getting dependency of 'luasocket-3.0-rc1': Package 'lua >=5.1,<5.3' needed, but selected at version '5.3.2'.
Getting luasocket-2.1-dev (source)...
 - trying another candidate due to: Error getting dependency of 'luasocket-2.1-dev': Package 'lua >=5.1,<5.3' needed, but selected at version '5.3.2'.
Getting luasocket-2.0.2 (source)...
 - trying another candidate due to: Error getting dependency of 'luasocket-2.0.2': Package 'lua ~>5.1' needed, but selected at version '5.3.2'.
Getting luasocket-scm (source)...
Cannot install package 'luasocket': Error getting dependency of 'luasocket-3.0-rc1': Package 'lua >=5.1,<5.3' needed, but selected at version '5.3.2'.

所以我搜索了一下，发现了这个页面：https://github.com/LuaDist/Repository/issues/221

这表示 lua 5.3.2 尚不支持，解决方法是使用 lua 5.2

所以，我非常乐观地盲目地运行了他建议的命令：

luadist.exe c:\lua52 install lua-5.2 luasec

它给了我以下信息：

C:\TDM-GCC-64\_bootstrap\_install\bin>luadist.exe c:\lua52 install lua-5.2
Finding out available versions of lua...
Getting lua-5.2 (source)...
Building lua-5.2...
Installation successful.

但是当我返回运行我的原始命令来测试部署（如上）时，我得到与上面相同的依赖错误。

我需要做什么才能让我的 LuaDist 从 5.3.2 切换到 5.2？

编辑：嗯，刚刚意识到我实际上错过了他的命令中的luasec。所以不知道我现在做了什么......

正确运行他的命令值得：

C:\TDM-GCC-64\_bootstrap\_install\bin>luadist.exe c:\lua52 install lua-5.2 luasec
Finding out available versions of luasec...
Getting luasec-0.4 (source)...
Finding out available versions of luasocket...
Getting luasocket-2.0.2 (source)...
 - trying another candidate due to: Error getting dependency of 'luasec-0.4': Error getting dependency of 'luasocket-2.0.2': Package 'lua ~>5.1' needed, but installed at version '5.2'.
Getting luasec-scm (source)...

 - trying another candidate due to: Error getting dependency of 'luasocket-2.0.2': Package 'lua ~>5.1' needed, but installed at version '5.2'.
Getting luasocket-2.0.2 (source)...

Answer 1

Luadist 基于 Lua 5.1（某些模块可以使用 5.2 或 5.3）.. 尝试使用 lua 5.1

luadist.exe c:\lua51 安装 lua-5.1.5 luasec
