如何在ubuntu上面安装luasocket

Posted 2023-03-20

参考技术A 最新版本lua5.2.1不支持luasocket，目前的luasocket只支持lua5.1和lua5.0.我到处上网查询如何在lua5.2.1中安装luasocket，但发现没有什么好的办法。最后，无奈之下安装了lua5.1,直接sudo apt-get 5.1 的方式安装lua5.1，然后再安装luasocket，我的系统有自带的luasocket不用安装，你可以到软件管理去查看一下，看有没有。然后在命令行里面敲lua5.1,进入lua5.1的命令行界面，在运行之前的luasocket相关的代码就可以运行成功了。
