标签： ruby-on-rails

这是我在控制台中的代码和输出：

root@a:/home/rails/car_main# bundle install

You have requested:
  rails = 4.2

The bundle currently has rails locked at 4.0.2.
Try running `bundle update rails`

这是我做的和输出：

在此之后，当我键入bundle install时，我仍然会收到错误

好。我怎么处理记忆？我用5美元的数字海洋水滴我的网站很简单。 我做了这个问题的建议： https://askubuntu.com/questions/253466/why-am-i-frequently-getting-this-cannot-allocate-memory-error 这是输出：

UPDATE2： 我按照评论链接中的建议打印出来 root@a:/home/rails/car_main# sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2 问题依然存在。 我现在会尝试停止postgres

Update 3我试图停止并开始发布postgres（我不确定我是否正确搜索了如何正确处理这些代码和输出：

更新4： 我打印htop：这是输出： enter image description here 我应该杀死哪些程序？

更新5：

我再次跑了bundle update然后我收到了一些错误并承诺安装捆绑器，所以我安装了它

root@a:/home/rails/car_main# apt-get install bundler 然后我再次捆绑更新：

root@a:/home/rails/car_main# bundle update
/usr/local/rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- bundler (LoadError)

    from /usr/bin/bundle:7:in `<main>'

更新6： 所以我再次运行捆绑更新，它给了我一个错误，无法安装sqlite3并建议手动安装它所以我做了它，并在这里输出：

root@a:/home/rails/car_main# gem  install sqlite3 -v '1.3.8'

我将删除gemfile中的sqlite版本希望它有所帮助

1 个答案:

答案 0 :(得分：0)

你的问题与内存不足有关，引用你的堆栈跟踪：Cannot allocate memory

考虑到独角兽工人吃掉你所有的公羊，你应该减少工人的数量，更多的信息here，

我注意到你已经杀死了所有进程;部署你的应用程序，如果它有足够的ram一切都应该没问题（顺便说一句：在部署时检查htop），如果问题仍然存在，或者某处存在内存泄漏（更新gem版本）或者你只是没有足够的内存 - 就像我说的那样价格你应该获得其他地方4倍的资源

如果您在服务器上运行所有这些命令，则应考虑在将来使用capistrano

关于更新5： 你应该运行gem install bundler（我假设你没有rvm？）
