我将我的 Rails 应用程序部署到我的本地 IP 地址。部署成功后，当我在浏览器中打开页面时，出现以下错误。一段时间以来，我一直被以下问题困扰。

It looks like Bundler could not find a gem. Maybe you didn't install all the gems that this application needs. To install your gems, please run:

    bundle install

If that didn't work, then the problem is probably caused by your application being run under a different environment than it's supposed to. Please check the following:

Is this app supposed to be run as the deploy user?
Is this app being run on the correct Ruby interpreter? Below you will see which Ruby interpreter Phusion Passenger attempted to use.
-------- The exception is as follows: -------

Could not find rake-10.4.2 in any of the sources (Bundler::GemNotFound)
  /home/deploy/.gem/ruby/2.2.2/gems/bundler-1.12.5/lib/bundler/spec_set.rb:95:in `block in materialize'
  /home/deploy/.gem/ruby/2.2.2/gems/bundler-1.12.5/lib/bundler/spec_set.rb:88:in `map!'
  ...

我验证了这个 stackoverflow 链接并尝试了以下操作。

我作为用户做了bundle install多次。deploy

我安装了 2 个版本的 rake，11.1.2并且10.4.2. 我清洗了11.1.2。确保此版本不存在于任何地方。

我看到 2 个 ruby​​ 版本。1.9.3 和 2.2.2。不确定这是否是问题所在。我没有手动安装 1.9.3。但我看到文件夹/usr/local/src/ruby-1.9.3-p448和/opt/rubies/ruby-1.9.3-p448. 当我尝试删除 1.9.3 时，使用sudo apt-get remove ruby 1.9.3得到以下结果。最后，我没有删除它，因为它试图删除passenger自己。

任何与此问题相关的帮助表示赞赏。

编辑：我仍然看到与 rake 11.1.2 相关的文件

这可能是问题吗？

好吧，我做了以下三个步骤，它开始工作了。这些来自Зелёный的评论。似乎我必须重新启动机器或其他东西才能反映更改。我不知道。

  1. 检查/etc/nginx/nginx.conf并确保值与命令passenger_ruby的输出相同which ruby
  2. 检查 rake 版本是否10.4.2通过执行rake --version. 否则清除所有 rake 并安装 rake 10.4.2
  3. bundle install

完成这些之后，我重新启动了机器并做cap prelive deploy了，应用程序启动了。
