Generally, you can access Julia by either starting from a Julia-baed environment or adding it through conda. But if you need, say, MATLAB and Julia, or Stata and Julia, you'll need to use the postInstall script.
First, choose the appropriate release from https://julialang.org/downloads/ and copy it into your clipboard.
Second, in your postInstall script, write something like:
curl -L https://julialang-s3.julialang.org/bin/linux/x64/1.2/julia-1.2.0-linux-x86_64.tar.gz | tar xz
(This will download Julia 1.2.0.)
Third, add to your
run script a line that adds Julia to the
PATH . If you are downloading Julia 1.2, your
run script will look like:
You can test that this worked by running
julia --version .
