Cannot install jspdf 1.5.3

问题

I need to convert html to pdf and I am using jspdf 1.5.2. It shows the error Cannot read property 'charAt' of undefined (using with html2canvas).

When I try to install jspdf 1.5.3 I get this:

npm ERR! path git
npm ERR! code ENOENT
npm ERR! errno ENOENT
npm ERR! syscall spawn git
npm ERR! enoent Error while executing:
npm ERR! enoent undefined ls-remote -h -t ssh://git@github.com/eligrey/FileSaver.js.git
npm ERR! enoent 
npm ERR! enoent 
npm ERR! enoent spawn git ENOENT
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent

I have read the other threads and none of them are helpful.

回答1:

With Version 1.5.3 of jsPDF they use a dependency directly from GitHUB. I'm assuming you're running the build in a CI? Either you install git + ssh or at that point return to version 1.5.2 of jsPDF. There's a bunch of issues in their bug tracker. This seems to be the relevant issue https://github.com/MrRio/jsPDF/issues/2208. It's marked fixed, but so far no new version 1.5.4.

回答2:

Try installing jspdf in git bash (GIT command line) using

npm i jspdf

For any passerby here because of html2pdf.js failing on CI, we're in the same boat.

It requires ^1.4.1, and resolves to 1.5.3 as of now, so either:

publish your own release on NPM rolling out the dependency fix,
install git on your Alpine image (docker: RUN apk add --no-cache git) and pray it'll pass through your enterprise firewall (it did not for me),
force 1.4.1 by requiring jsPDF in your package.json, and commit with the package-lock.json (worked for me).
