I have tried doing the following but it did not solve the problem

sudo rm -rf ~/.cache/luarocks
sudo rm -rf ~/.luarocks
./install.sh

Further, I have tried doing this, but even this was not usefule

curl -s https://raw.githubusercontent.com/torch/ezinstall/master/clean-old.sh | bash

cd ~/torch

./clean.sh

./install.sh

I ran ./luarocks --verbose install penlight, which is giving the following

Hi,

Did you had lua installed on your system before installing torch?

It looks like your `luarocks` is not the one provided by torch and thus cannot find torch packages

[vishnu lokhande]

I installed lua5.3 after installing torch. Should I remove it?

[alban desmaison]

Do you use it for another project?

The simplest would be to uninstall it. Otherwise see below.

The problem here is that torch has its version of lua. But the `luarocks` that is in the path is not the one from torch. so you cannot install torch packages with it.

You can try to run `. /home/vishnu/torch/install/bin/torch-activate` before running torch, this should make sure that you use the lua version installed with torch.

Or use directly `/home/vishnu/torch/install/bin/luarocks` as luarocks to install torch packages

I don't understand the cause. But I had a similar problem. I had installed torch7 in my home directory, using the instructions on the torch7 website. That failed to put the luarocks manifest anyplace where lua could see it.  (Failed in other ways as well.)  I did "rm -rf torch" to remove it all, and re-installed torch7 using the instructions from here.  That uses a different install script buried within the git repository, which worked for me on a Ubuntu 15.10 VirtualBox VM.  (Note that a VM probably can't use the GPU.)

I keep getting this error when I run the line "curl -s https://raw.githubusercontent.com/torch/ezinstall/master/install-all | bash". Also, I'm  not able to run a test lua file with the command "th test.lua"

Enter code here...Error: Your user does not have write permissions in /usr/local/lib/luarocks/rocks

I removed everything including lua, luajit from the system and reinstalled torch as per this. It's working now.
