I’m currently developing an electron app that has, at some point, to convert an HTML file into a PDF file. For this purpose, I use the native node module html-pdf which is based on phantomjs.
It works well when the application is not packed but when it is under asar, there is an uncaught exception because html-pdf cannot spawn a child process.
The stack error
internal/child_process.js:302 Uncaught Error: spawn ENOTDIR
exports._errnoException @ util.js:890
ChildProcess.spawn @ internal/child_process.js:302
exports.spawn @ child_process.js:379
PdfExec @ /Users/graphfx/html2pdf/html2pdf.asar/node_modules/html-pdf/lib/…:87
PdfToFile @ /Users/graphfx/html2pdf/html2pdf.asar/node_modules/html-pdf/lib/…:83
convert @ index.html:35
onclick @ index.html:19
I suppose that is due to the asar Limitations on Node API but I really need to pack my app in asar due to the 260 character path length limit on Windows.
I have also tried using the option --unpack-dir 'node_modules' when building the asar package but the problem persists.
Reproduce the error
git clone https://github.com/Graphfx/html2pdf
cd html2pdf
npm install
npm run asar-pack
npm run start-asar
Does someone know how solve this problem?
