Heroku预编译资产失败

Question

My app is suddenly not working after an update. Not sure what's going wrong. Basically, when I push to heroku, I get these errors:

Precompiling assets failed, enabling runtime asset compilation
Injecting rails31_enable_runtime_asset_compilation

And a little higher up:

   rake aborted!
   Unexpected token: operator (>) (line: 19073, col: 9, pos: 605247)

When I actually load up the site ("We're sorry, but something went wrong"), and look at the heroku logs, I get this:

Load path: /app

(Kreon is an additional font I added a while back that's been working fine. custom.css.scss is my main css file, and the first line is where I import bootstrap in a way that hasn't changed and has worked forever).

I searched for how to deal with the "File to import not found or unreadable: bootstrap" error, and landed on this discussion and checked out the relevant heroku troubleshoot page , but changing assets.compile to true in my production.rb file led to the heroku push errors above, and the troubleshoot page didn't seem to have much relevant to my specific problem. Not really sure what's going on here, so I'm just going to put a bunch of possibly relevant code below.

The line that's really throwing me is this one in my heroku push log:

Unexpected token: operator (>) (line: 19073, col: 9, pos: 605247)

The issue, is I have no idea what file to look in for this troublesome ">". Any ideas how to read that line/col/pos nomenclature to find the actual offending code snippet?

Thanks.

Answer 1

STart with line 1 of app/assets/stylesheets/custom.css.scss and look for an errant > . Also look to make sure that application.scss is what you expect.

Also just rename custom.css.scss to just custom.scss Heck, that may do it.

Answer 2

The same thing happened to me as well,
"Precompiling assets failed." while pushing to heroku,
In my development environment I had an error in my css:
".........
cursor: pointer
color: #808080;"

missing the ";" after the "pointer", the development environment didn't mind the error, but Heroku's PreCompile task did.

Some other Problems might be caused by duplicate named file, with "css" and "css.scss" suffixes.

Answer 3

Try this in the terminal:

rake assets:precompile RAILS_ENV=production --trace

Better than trying to push on heroku.

I just had the same errors. The problem was:

• the config.secret_key of devise was commented
• syntax_error in a javascript file ( an "of" instead of an "in" in a for loop)
