add troubleshooting of cairo errors #1

Closed jimthedev closed 8 years ago

jimthedev commented 8 years ago

Cairo is required by canvas. If your *nix build doesn't have it, you should install it.

This adds a troubleshooting section with the error and the solution for OSX.

I'd rather not include a long section in troubleshooting common errors that stem from dependencies. Maybe a reference link would do?

On Debian Jessie (GNU/Linux), I had to install the following to build shots:

millette commented 8 years ago

Well, it built, it runs, grabs the versions from archive.org (in pages/) but screenshots/ ends up empty and so are the generated .gif and png images.

bevacqua commented 8 years ago

It takes a while for the screenshots to be taken. Use -v in the CLI or DEBUG=shots node app to print diagnostic info

millette commented 8 years ago

Looking at the code, I'm not sure where the .png images are supposed to come from. Just running waybackpack generates html files, but no html.png files. So maybe my problem is with that dependency. Sorry for all the noise.

@bevacqua I have having the same problem. I never get screenshots. The process exits right away and I get the following when using DEBUG=shots:

What does shot.js contain? Please create a separate issue.

@bevacqua Good idea. Created #3 to dig more into this.
