Unable to run pdfLatex #10

Closed jamesqquick closed 6 years ago

jamesqquick commented 6 years ago

I've copied over the simple example from the repo, and tried to run it but I get an unhandled 'error' each time. Not getting insightful feedback from this, so not sure how to debug...


events.js:163
      throw er; // Unhandled 'error' event
      ^

Error: Error: Unable to run pdflatex command.

Do you have latex installed on your computer? Meaning if you open up a terminal and type in pdflatex --version, do you get any output?

jamesqquick commented 6 years ago

Thanks for the quick response. I do not have that installed. I didn't see that as a requirement in the ReadMe. Is there a recommended way to install?

jamesqquick commented 6 years ago

Ok got rid of that error by doing an install of Latex. didn't realize that was a separate thing to install. It's also surprisingly big, oh well. I'm going to do a pull request and add a line to readme to install.

Thanks again!

Even if I have latex installed in my local machine. I am having same issue.

saadq commented 3 years ago

Potentially a PATH issue then? Are you able to run pdflatex from your terminal?

I have install latex and able to run the pdflatex command. But I still get the error: Error: Error: Unable to run pdflatex command.

In your terminal, can you type which pdflatex and see what path is printed?

And then can you try passing the entire path to the latex function options.

const input = fs.createReadStream('input.tex')
const output = fs.createWriteStream('output.pdf')

const pdf = latex(input, {
  cmd: '/path/to/pdflatex'
})

pdf.pipe(output)
pdf.on('error', err => console.error(err))
pdf.on('finish', () => console.log('PDF generated!'))

const createNewPdf = await new Promise((resolve, reject) => { const input = fs.createReadStream(path.join(dirname + "/../latex/pledge.tex")); const output = fs.createWriteStream(path.join(dirname + "/../latex/output.pdf")); const pdf = latex(input, { cmd: "/usr/bin/pdflatex", inputs: path.join(__dirname + "/../latex/"), }); pdf.pipe(output); pdf.on("error", (err) => { console.log(err); logger.error("Pocket services v2", "upload to s3 inside promise", err); reject(false); }); pdf.on("finish", () => { logger.info("Pocket services v2", "upload to s3", "File Created"); resolve(true); }); });
