How do I get node working? I've managed to download it and when I try to use
'npm install -g express' I get the following error:

Confirmed, it is an issue with loop mounting node.tcz I will fix it in May. As a temporary fix create an empty directory, loop mount node.tcz and copy content to file system, it will work.

Code: [Select]
sudo su
cd /
mkdir node
mount -o loop /mnt/mmcblk0p2/tce/optional/node.tcz /node
cp -r /node/usr /

Make sure it is not loop mounted already, remove node.tcz from onboot.lst

Alternative solution to copy all extensions to RAM at startup if they leave free RAM.

Code: [Select]
sudo touch /mnt/mmcblk0p2/tce/copy2fs.flg
sudo reboot

will make it. In this case node.tcz must be in onboot.lst

Most clean is to fix tcz in repo. Offered solutions are different but both working.

One boots a bit slower and using more memory, other requires some scripting. Try each version to learn TC :)
