Similar errors here with Light Table 0.2.5 on 32-bit Arch Linux. And I too had to do a libudev symlink, as mentioned by @as above.
Are there older versions of Light Table available somewhere, so we can at least use those in the meantime?
Full description:
I installed Light Table from the Arch User Repository (AUR), which contains version 0.2.5-1.
Running lighttable on the terminal opens a window with the address nw:blank and NODE-WEBKIT written in ASCII art, with the following errors:
