How to install lua modules on linux?

To install Lua modules on Linux, you can follow these steps:

1. Use the package manager specific to your Linux distribution to install the Lua interpreter. For example, on Debian-based systems (e.g. Ubuntu), you can run the following command: sudo apt-get install lua5.3 This command installs the latest stable version of Lua. You can replace lua5.3 with lua5.2 or lua5.1 depending on your system's available version.
2. Install the luarocks package manager, which helps to easily install Lua modules. For Debian-based systems, run: sudo apt-get install luarocks
3. Use luarocks to install Lua modules. For example, if you want to install the luasocket module, run: sudo luarocks install luasocket This command fetches the luasocket module from the LuaRocks repository and installs it in your Lua module path.
4. By default, luarocks installs modules in system directories. However, if you need to install modules locally (without administrative permissions), you can use the --local flag. For instance: luarocks install --local luasocket This command installs the luasocket module in the current user's home directory.

Note that some modules may have additional dependencies. You can generally find information about a module's specific installation requirements in its documentation.
