Question: I have the following luarocks:

```
package = "project-name"
version = "1.0-1"
source = {
   url = "..."
}
description = {
   summary = "etc"
   detailed = [[]],
   homepage = ""
}
dependencies = {
   "lua >= 5.1, < 5.2",
   "busted >= 2.0.rc12",
   "lua-requests >= 1.1",
   "json-lua >= 0.1",
   "lua-resty-dogstatsd >= 1.0.1"
}
build = {
    type = "builtin",
    modules = {
        ["project-name"] = "project/init.lua"
    }
}

```

How do I install the dependencies? Doing `luarocks install` says I'm missing arguments. Not sure what to do here.

Answer: 
To install a single dependency manually, you can run

```
luarocks install <dep-name>

```

You can append an optional version such as

```
luarocks install lua-resty-jwt 0.1.11-0

```

To install all dependencies listed in the Rockspec file,

```
luarocks install --only-deps <rockspec_file>

```

From the manual of `luarocks install`:

> 
> --only-deps Installs only the dependencies of the rock.

Alternatively, you can simply run

```
luarocks make

```

which will also install missing dependencies for you. However, do note that it may not be what you want, depending on your needs:

As I understand, the question is although you install with that rockspec, it doesn’t install rocks declared in dependencies. 
Firstly could you do following command to check if above dependencies exist?

Command: `luarocks list | grep [dependency_name]`

For Example: `luarocks list | grep json-lua`

(luarocks list list all the rocks be installed)
