Pin myst_parser to 0.11.2 to avoid no markdown_it.extensions.dollarmath

[echarles]

Yesterday myst-parser 0.12.0 has been published (https://pypi.org/project/myst-parser/0.12.0) and RTD build is failing with

    from myst_parser.main import default_parser, MdParserConfig
  File "/home/docs/checkouts/readthedocs.org/user_builds/jupyterlab-benchmarks/envs/latest/lib/python3.7/site-packages/myst_parser/main.py", line 13, in <module>
    from markdown_it.extensions.dollarmath import dollarmath_plugin
ModuleNotFoundError: No module named 'markdown_it.extensions.dollarmath'

Pinning to 0.11.2 to hopefully fix this

LGTM

Yes, this fixes the issue.
I have opened executablebooks/MyST-Parser#220

this is why! you should remove this line as its a dependancy clash with myst-parser 0.12

[chrisjsewell]

you can also unpin sphinx from <3 if you want 😄

Have done both and works locally. Will open another pr and hopefully rtd will be happy. Thx a lot!

No worries! I guess it might depend on what version of pip you have, as to how it resolves the conflict
