MacOS 使用 luarocks+wrk+luajit

luarocks 默認使用的是 lua 5.4 版本，一些工具，例如 wrk 使用的 lua 5.1，那么 luarocks 在安裝依賴的時候就需要指定 lua 5.1。

luarocks config 配置 lua 5.1

請確保已經安裝了 lua5.1 或者 luajit，本處使用 luajit。

luarocks config lua_dir /opt/homebrew/opt/luajit

Lua version will default to 5.1 in /opt/homebrew/etc/luarocks
Wrotelua_version = "5.1"
to/opt/homebrew/etc/luarocks/config-5.1.lua
qyvlik@qyvlikdeMacBook-Pro luarocks % luarocks config lua_dir /opt/homebrew/opt/luajit
Wrotevariables.LUA = "/opt/homebrew/opt/luajit/bin/luajit"variables.LUA_BINDIR = "/opt/homebrew/opt/luajit/bin"variables.LUA_DIR = "/opt/homebrew/opt/luajit"variables.LUA_INCDIR = "/opt/homebrew/opt/luajit/include/luajit-2.1"variables.LUA_LIBDIR = "/opt/homebrew/opt/luajit/lib"
to/opt/homebrew/etc/luarocks/config-5.1.lua

寫入文件的位置 /opt/homebrew/etc/luarocks/config-5.1.lua，內容如下：

-- LuaRocks configurationrocks_trees = {{ name = "user", root = home .. "/.luarocks" };{ name = "system", root = "/opt/homebrew" };
}
variables = {LUA_DIR = "/opt/homebrew/opt/luajit";LUA_BINDIR = "/opt/homebrew/opt/luajit/bin";LUA_VERSION = "5.1";LUA = "/opt/homebrew/opt/luajit/bin/luajit";
}

luarocks config lua_version 5.1

Wrotelua_version = "5.1"
to/opt/homebrew/etc/luarocks/config-5.1.lua

寫入文件的位置 /opt/homebrew/etc/luarocks/default-lua-version.lua，內容如下：

return "5.1"

luarocks install snowflake

如果需要使用代理安裝，請在執行如下命令，請確保有對應的 proxy 服務在運行。

export all_proxy=http://127.0.0.1:3128

安裝需要指定 --lua-version=5.1。

luarocks install snowflake --lua-version=5.1

沒有指定 lua-version
