Some builds fail because of an error with phantomjs, checking this blog I change the circle config to install newest version but the error still happening. When I get this error I just need to rebuild and everithing works well again (without any code change) info: - Rails 4.2 - Ruby 2.3 ```auto # circle.yml machine: pre: - sudo curl --output /usr/local/bin/phantomjs https://s3.amazonaws.com/circle-downloads/phantomjs-2.1.1 ``` ```auto # Error log bundle exec rake jasmine:ci Thin web server (v1.6.3 codename Protein Powder) Maximum connections set to 1024 Listening on 0.0.0.0:57687, CTRL+C to stop Waiting for jasmine server on 57687... jasmine server started Phantomjs does not appear to be installed in /home/ubuntu/.phantomjs/1.9.8/x86_64-linux/bin/phantomjs, installing! % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 0 0 0 333 0 0 6540 0 --:--:-- --:--:-- --:--:-- 6540 bunzip2: phantomjs-1.9.8-linux-x86_64.tar.bz2 is not a bzip2 file. tar: phantomjs-1.9.8-linux-x86_64.tar: Cannot open: No such file or directory tar: Error is not recoverable: exiting now rake aborted!
