Cannot import dash-html-components with dash==0.23.1 and python>=3.7

[rmarren1]

See discussion here: https://community.plot.ly/t/error-running-dash-after-upgrade-of-plotly/12507/5?u=chriddyp

It looks like the IDE support PR can not handle components which have arguments that are Python Keywords.

None of the core components have had these in 3.6, but that changed in 3.7.

The PR #325 is a patch to fix this, namely it checks if each argument is in keyword.kwlist, and if it is Dash will accept that keyword via **kwargs rather than via a named argument.

A SyntaxError: invalid syntax is thrown at dash_html_components/Script.py, line 48 when attempting to import dash-html-components with dash==0.23.1 and python>=3.7.

Fix is to downgrade dash to 0.22.0, patch will be merged soon: #325

Fixed in dash==0.24.1

This is still not working for me with dash==0.26.6. I tried reinstalling and downgrading to dash==0.24.1, and it still fails with the same syntax error.

Try dash-html-components==0.12.0. It looks like 0.13.0 was built against py2.7 or py3.6 causing this error.

@rmarren1 I just released 0.13.0 with the dev bundle support, I didn't touch the .py files and didn't regenerate them. The .py files in the repo are bad.

[rmarren1]

Yeah the files in the repo are against 3.6. I'll change them to be against 3.7 and release 0.13.1 to fix this

[rmarren1]

@rmbarley Should work with dash-html-components==0.13.2 just released as a patch
