Heroku上没有-j4的包

Heroku现在似乎默认与

-j4

并行绑定，因为我在推送日志中看到：

正在运行：bundle安装--无开发：test:staging--路径 供应商/捆绑包--bin捆绑包供应商/捆绑包/bin-j4--部署

这会抛出一个错误，我可以用它在本地复制

bundle install -j4

本地错误为：

/Users/Emma/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/2.0.0/thread.rb:72:in `sleep': No live threads left. Deadlock? from /Users/Emma/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/2.0.0/thread.rb:72:in `block (2 levels) in wait'

尝试部署时出现的错误是：

   /tmp/build_a49f4fc2-73b3-4101-9b67-f795fa643429/vendor/ruby-2.0.0/lib/ruby/2.0.0/thread.rb:72:in `sleep': No live threads left. Deadlock? (fatal)

我如何才能迫使Heroku停止并行捆绑宝石的尝试

有些gem在并行安装时遇到问题，应该像下面这样向bundler/bundler报告

在此文件中，这是问题行：

gem 'formtastic-bootstrap', " ~> 2.0.0"

改为

gem 'formtastic-bootstrap', "2.1.3"

它是有效的。我就是这样发现的：

安装bundler最新版本

$gem安装bundler

然后运行

$bundle install-j4

这将尝试并行安装最多4个gem

当它失败并显示此错误消息时

Unfortunately, a fatal error has occurred. Please see the Bundler troubleshooting documentation at http://bit.ly/bundler-issues. Thanks!
/Users/schneems/.rbenv/versions/2.1.0/lib/ruby/gems/2.1.0/gems/bundler-1.5.1/lib/bundler/parallel_workers/worker.rb:33:in `pop': No live threads left. Deadlock? (fatal)

通过运行查找未签出的Gem

$ bundle list
Could not find gem 'formtastic-bootstrap (~> 2.0.0) ruby' in the gems available on this machine.

注释掉Gemfile中的那一行，然后重复，直到整个Gemfile安装完毕。安装后，逐渐添加回您评论的内容。可能更高版本的Gem能够解决这个问题
