Syntax Error for @font-face

[yummydum]

Hi, I get the following error message, and I need help.

Situation

I installed commuter by yarn, launched the server, and accessed localhost:4000. Then I get a 500:Internal Server Error. The log shows the following error.

/usr/local/share/.config/yarn/global/node_modules/github-markdown-css/github-markdown.css:1
@font-face {
^

SyntaxError: Invalid or unexpected token

Reproduction

By the following dockerfile,

FROM node:latest

RUN yarn global add @nteract/commuter

EXPOSE 4000

CMD commuter

Build:docker build . -t commuter Run:docker run -p 4000:4000 commuter. Then open the browser and access localhost:4000.

Thanks for your help in advance.

I get exactly the same having installed via npm. I resolved it (temporarily at least) by downgrading my version of @nteract/markdown to 4.0.0. It then loads up ok...

Hello @robepdavis!

Thanks for opening this issue! This is related to an update that was made to the @nteract/markdown package. You can read more about this at https://github.com/nteract/nteract/issues/4777.

The short-term fix is to add a css-loader to the configuration for commuter.

The long-term fix is to resolve the issue above from the nteract monorepo.

Would you be interested in helping resolve this bug with a contribution?

+1. I am also facing the same issue.

@captainsafia could you provide a minimal example of adding a css-loader to the configuration?

Hello folks! Apologies for the delay!

We ended up removing the github-markdown.css dependency that was causing this error in the latest version of the nteract/outputs package.

Since nteract/markdown is pinned to the major version, running npm install on the commuter should trigger bringing in the latest version of nteract/markdown (v4.3.7) that does not have this issue.

Can you let me know how that works for you?

I no longer receive this error, but now I have a new error. Using yarn dev on the master branch, I am able to get a listing of the notebooks, but then it fails with an error about a missing module d3-contour (see nteract/vega-embed-v3#3).

However, that's a new issue.

Thanks for verifying the resolution, @dhpollack.

As for the other issue, I'll see if I can get someone who's worked on the vega packages to review that pull request you linked to so we can get a fix out.

I'll go ahead and close this issue now.
