Re: Problem with luarocks unpack

[Eduardo Ochs <eduardoochs@...>]

Hi Ką,

thanks -- I didn't know how to use "--tree", now I sort of do -- but
you forgot the "unpack" step...

Here are complete versions of your commands:


  # Version 1
  rm -Rv /tmp/rock/
  mkdir  /tmp/rock/
  cd     /tmp/rock/
  mkdir                   ./tree
  luarocks install --tree ./tree luarocks
  ./tree/bin/luarocks download stacktraceplus
  ./tree/bin/luarocks unpack   stacktraceplus

  # Version 2
  rm -Rv /tmp/rock/
  mkdir  /tmp/rock/
  cd     /tmp/rock/
  mkdir                      ./tree
  luarocks install    --tree ./tree luarocks
  ./tree/bin/luarocks --tree ./tree download stacktraceplus
  ./tree/bin/luarocks --tree ./tree unpack   stacktraceplus


I tested them with luarocks 2.4.2 (from Debian) and with luarocks
3.2.1 (from git). With 2.4.2 this step

  luarocks install    --tree ./tree luarocks

fails with:

  Error: Rockspec format 3.0 is not supported, please upgrade LuaRocks.

and with luarocks 3.2.1 that step works, but this one

  ./tree/bin/luarocks --tree ./tree unpack   stacktraceplus

fails with:

  Error: Failed copying unpacked rockspec into unpacked source directory.
