Asmod4n · 2015-01-25T09:12:13Z

This has been solved in nio4r 1.1

digitalextremist · 2015-01-25T22:34:12Z

This is fixed in 1.1 as @Asmod4n said. Are you able to upgrade or is there some part of 1.0.0 you need that 1.1 doesn't support?

andersennl · 2015-01-26T18:46:46Z

Well, when I try to use Ruby 2.2.0 for my Rails 3 project and do a bundle install, something seems to be dependent on the 1.0 version of this gem. A prior installation of nio4r 1.1 didn't help.

tarcieri · 2015-01-26T18:48:02Z

Have you tried bundle update nio4r? I can't imagine anything would pin to 1.0.0.

Asmod4n · 2015-01-26T18:49:26Z

After looking at celluloid and celluloid-io, i also cannot see anything which could pin nio4r to 1.0

andersennl · 2015-01-26T18:58:19Z

Ah I actually read the error wrong. But the errors I'm getting are interesting. When I try a bundle update nio4r, it fails with this error:
https://gist.github.com/andersennl/ad254d65649807cde263

gem install libv8 -v '3.16.14.3' fails like this:
https://gist.github.com/andersennl/6dd35b923247ca3c6218

Doom loop :)

Asmod4n · 2015-01-26T19:01:37Z

Oh the joy that is libv8 ...

tarcieri · 2015-01-26T19:05:01Z

@andersennl try pinning libv8's version to the one that's working for you

andersennl · 2015-01-26T19:11:11Z

Hm okay I'll try to figure out which one that could be. Thanks for your help!

asecondwill · 2015-03-31T15:27:29Z

@andersennl - what happened with this. I'm getting the same error

garciadanny · 2015-06-10T18:48:54Z

Anyone figure out how to fix this issue?

tarcieri · 2015-06-10T22:08:51Z

@garciadanny update nio4r if you can

andersennl · 2015-07-19T13:55:29Z

Sorry I didn't see the new questions here. I made it work like this:

bundle update nio4r

rshejnberg · 2015-11-10T21:37:00Z

Encountering this issue. Both attempting to install version 1.1 and running bundle update nio4r fail.

tarcieri · 2015-11-10T22:40:04Z

@rshejnberg if you'd like us to help, you'll need to provide a lot more information, like:

Your OS / version
An output of where the error is occurring

flushentitypacket · 2015-11-17T17:07:28Z

bundle update nio4r solved this for me.

bobzhen · 2015-12-31T06:36:32Z

bundle update nio4r

rocks!!!

joost · 2016-04-30T10:48:33Z

+1 for bundle update nio4r :)

eric-khoury · 2016-05-03T08:01:58Z

Had a similar problem on ubuntu 14.04 with ruby 2.3.0. Turned out I was missing a gmp package. This solved the issue for me: sudo apt-get install libgmp3-dev

assafshomer · 2016-05-24T08:42:52Z

also for me, bundle update nio4r did the trick. Thx!

jaredchu · 2016-08-26T05:46:22Z

bundle update nio4r
Work like a champ!

rahulrajaram · 2016-12-19T08:02:23Z

If you are using mac, it might be that you need to update Xcode. That was my problem. I got the hint here
