Epub, Mobi, and PDF formats are not generated anymore

[ronaldborman]

During the last builds the step 'Run gitbook install' was not successful so the build failed and subsequent steps were skipped. The returned error is TypeError: cb.apply is not a function at FSReqCallback.oncomplete.

As a result the Epub, Mobi, and PDF formats are not generated anymore with Github Actions.

This appears to be an issue with gitbook-cli: GitbookIO/gitbook-cli#110.
It has a dependency on an older version of graceful-fs where this problem hasn't been resolved for Node 12. gitbook-cli is deprecated so this won't get fixed but judging from the comments, it looks like there is an effort to maintain a fork of it. I modified the build script in this repo to downgrade to Node 10 and built the books here.

I made a Dockerfile that builds and image containing the output in /output/.

FROM node:10

RUN apt update
RUN apt install calibre-bin -y
RUN npm install -g gitbook-cli
WORKDIR /app/
COPY . .

RUN gitbook install
RUN mkdir /output

RUN gitbook mobi . /output/typescript-book.mobi`

Just make sure that the context for the image build is the root of the book's repo.

Built the book just now from master:
