Same problem here with bootstrap_and_overrides.css.less as I upgraded the gem yesterday.

[nhapke]

Same problem here too.

[arashm]

+1 for solving this. I've the same problem here.

[penchiang]

+1 for solving this. Should we try 2.3.3 for temp fix?

[gwoemul]

downgrading to 2.3.3 works for me at the moment, but i guess there should be some sort of a permanent fix

[penchiang]

I just downgraded to 2.3.3 and it works for the time being. Also, this only happened recently when I upgrade the ruby to 2.0.0-p247.

+1 … Some problem here too.

It may also be worth noting that simply using less-rails 2.3.3 may not be the entire solution as in my case. I also need to use less 2.3.2 instead of 2.3.3 to remove this error.

If you use "twitter-bootstrap-rails" then you should specify version:

gem 'twitter-bootstrap-rails', "~> 2.2.8"

After that update less-rails and run

rails g bootstrap:install -f

This helped me.

@Loremaster thanks, that helped me as well.

Found a fix. Either upgrade Twitter Bootstrap or manually replace the syntax change described below:

The upgrade introduced a backwards-incompatible change with everyone using Bootstrap's mixins.less file.

The problem is that when metaskills/less-rails upgraded from v2.3.3 to v2.4.0, it upgraded cowboyd/less.rb from v2.3.1 to v2.4.0, which upgraded less/less.js from v1.3.3 to v1.4.2, which introduced a backwards incompatible change in v1.4.0 beta, specifically the line that says:

(~"@var") selector interpolation is removed. Use @{var} in selectors to have variable selectors

There are a handful of places in Bootstrap's mixins.less file where that pattern shows up. You'll have to search for them manually. Also check out: http://stackoverflow.com/questions/19553367/less-unrecognized-input-error-when-using-bootstrap

Thanks @Loremaster, you saved the day.

@emorikawa thanks for the detailed description.

Anyway there's nothing we can fix in this gem :( Feel free to use older version of less-rails to get older less.js.
