Description

I was trying to build material locally by following the contributing guide.
The setting up process was good, but yarn run watch errored.
Here is the log:

yarn run v1.3.2
$ make -j watch
rm -rf material
/Users/zoubin/Workspace/mt/mkdocs-material/mkdocs-material/node_modules/.bin/webpack --watch
while [ ! -d "./material" ]; do sleep 1; done

Webpack is watching the files…

Hmm that's strange as I cannot reproduce it. Which version of Jinja do you have installed?

pip show jinja2

On my machine this prints:

Sorry for the delay.
On my mac,

pip show jinja2

prints:

This is a little regression that is incompatible with Jinja 2.7, as Jinja changed the behavior of imports and contexts in 2.9. Upgrading it to >2.9 will fix the issue, but I will also provide a fix shortly.
