找不到“位”的LuaRocks模块

Question

我正在尝试使用torch7和LUA运行代码，但出现此错误。

    usr/local/torch/install/share/lua/5.2/trepl/init.lua:389: module 'bit' not found: No LuaRocks module found for 'bit'
        no field package.preload['bit']

我尝试在我的配置文件中本地安装“位”，因为我没有正在使用的服务器上的写入权限（Ubuntu 18.04）：

luarocks install --deps bit --local

但是它显示：Error: No results matching query were found.

我该如何解决？
