Python 3: "make template" fails

[spoeschel]

Currently the template make target (also invoked as part of the all target) of the release/3.0 branch fails:

$ make template
npm update nunjucks
node_modules/nunjucks/bin/precompile ebu_tt_live/ui/user_input_producer/template/user_input_producer_template.xml > ebu_tt_live/ui/user_input_producer/template/user_input_producer_template.js
/home/stefan/DL-Source/ebu-tt-live-toolkit3/node_modules/nunjucks/src/precompile.js:114
  name = name.replace(/\\/g, '/');
              ^

TypeError: name.replace is not a function

It seems that the name option of the precompile script of Nunjucks (v3.2.1) plays a role - though the option is optional if a file is specified, as far as I can see.

Thanks @spoeschel I'll look to see if we've fixed this in our fork.

Ah, no, we haven't. I can reproduce this.

Same issue here, it's nothing to do with your Python version (as issue title implies). I got around it with:

npm install nunjucks@3.2.0

(instead of npm install nunjucks).
