Image cant build

[Forsakenrox]

Image cant build.
Steps to reproduce:

git clone https://github.com/SWI-Prolog/docker-swish
cd docker-swish
make image

The output error is:

Dockerfile:13
--------------------
  12 |         (cd swish && git checkout -q ${SWISH_SHA1})
  13 | >>> RUN make -C /swish RJS="nodejs /usr/share/nodejs/requirejs/r.js" \
  14 | >>>      yarn-zip packs min
  15 |
--------------------
ERROR: failed to solve: process "/bin/sh -c make -C /swish RJS=\"nodejs /usr/share/nodejs/requirejs/r.js\" \tyarn-zip packs min" did not complete successfully: exit code: 2
make: *** [Makefile:20: image] Error 1

Thanks. Pushed a fix to add uglifyjs to the dependencies and updated the SWISH version. Builds for me now.
