osx - Rails wkhtmltopdf not working on Yosemite MAC -

-

I upgraded my Mac to Yosemite and now wkhtmltopdf is not working in a rail app. With the browser's time "Data Not Received"

I am using PDFkit - 

  config.wktmltopdf = Rails.root.join ('bin', 'Wkhtmltopdf') in it. To_s if Rails.env.development?

I have 2 files: 

  wkhtmltopdf wkhtmltopdf-amd64

I tried to add:

Mani 'wkhtmltopdf-binary'

I get the same result

I do not find any errors in the rail log Browser it shows "Load the webpage Unable to do because the server did not send any data. Error code: ERR_EMPTY_RESPONSE "

Thanks for the help!

UPDATE 1

I tried: brew install wkhtmltopdf - But first, I had to reinstall Bru.

Get the same results.

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
