gitbook pdf . ../mybook.pdf create a good pdf.

Thanks for your notice

I think we might face a similar bug due to using the mathjax plugin. Building works fine but rendering a PDF leads to the follwing error message:

Did you solved this problem?I met the same error, but I don't know how to solve it.

0nse commented 6 years ago

Unfortunately, I have not.

allenyllee commented 6 years ago

Hi, you can try my modified katex plugin allenyllee/plugin-katex: Math typesetting using KaTex

It can build and render pdf without error, but still have some format issue...

It can correctly display this: $$ o_j=softmax(z_j)=\frac{e^{z_j}}{\sum_j e^{z_j}} $$ but can not do for this: $$ z_j=\sumi w{ij} y_i+b_j $$ very strange...

If someone can fix it, please let me know. Thanks!

My solution: replace "mathjax" with "mathjax@https://github.com/OrgVue/gitbook-plugin-mathjax.git#speech-fix" in book.json.

The issue is caused by a breaking change in speech-rule-engine@2 that was released in August 2017. GitBook plugin mathjax requires mathjax-node@0.5.2, which in turn requires speech-rule-engine@* (simply the latest version).

My fork freezes speech-rule-engine to v1, which resolves speech.processExpression is not a function (this method was removed in speech-rule-engine@2).

@kachkaev thank you, it started working in that way:

but now I have a

I have installed npm install svgexport -g that was required. This issue seems related to https://github.com/mobxjs/mobx/issues/397 actually.
