Trouble running luarocks 2.2.0 in Windows - 'pwd' not recognized

问题

I installed luarocks in 64-bit Windows 7, and everything installed correctly, but when I try to run luarocks I get the following error:

'pwd' is not recognized as an internal or external command,
operable program or batch file.
C:\Program Files (x86)\Lua\5.1\lua: ... Files (x86)\Lua\5.1\lua/luarocks\fs\win3
2\tools.lua:24: attempt to index local 'directory' (a nil value)

I'm really not sure what I'm doing wrong and I've scoured the internet for answers and turned up nothing.

I added the tools directory to my Windows Path variable and this resolved the issue. I am still having trouble getting luarocks to work for other reasons, but I will post those issues in a separate question.
