处于部署模式的捆绑器找不到宝石 [英] Bundler in deployment mode does not find Gems

问题描述

当我的托管人迁移服务器时，我在Capistrano设置上苦苦挣扎：

I was heavily struggling with my Capistrano Setup, when my Hoster migrated the server:

迁移服务器后，Capistrano3部署失败

我遇到的一件事是捆绑器上的工作正常，现在看来是一团糟：

One thing I ran into that used to work just fine on the old machine and now seems to be a mess is bundler:

我可以通过Capistrano成功运行捆绑器：

I could successfully run bundler through Capistrano:

cap staging bundler:install

在服务器上的以下命令中

This resulted in the following command on the server

/usr/bin/env bundle install --binstubs \ 
/var/www/mydomain.com/subdomains/dev/shared/bin \
--path /var/www/mydomain.com/subdomains/dev/shared/bundle \
--without development test \
--deployment

但是现在我运行服务器 cap登台deploy：start_passenger 结果如下：

But now when I ran my server cap staging deploy:start_passenger which results in the following:

/usr/bin/env passenger start --socket tmp/passenger.socket -e staging -d

然后我在日志文件中看到错误，表明缺少Rake：

Then I got the error in my log file, that Rake was missing:

Could not find rake-10.2.2 in any of the sources (Bundler::GemNotFound)
<pre>  /var/www/mydomain.com/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/bundler-1.7.3/lib/bundler/spec_set.rb:92:in `block in materialize&#39;

非常奇怪的是，红宝石版本 2.1.2 （我真正使用的那个）显示为 2.1.0。我的项目中没有可见的对 2.1.0`的引用，并且我的Gemfile包含：

What is very weird, is the fact that the ruby version 2.1.2(the one I really use) shows up with 2.1.0. I have no visible reference to2.1.0` in my project, and my Gemfile contains:

ruby '2.1.2'

由于在服务器上使用了RBENV，所以我可以运行 rbenv版本：

Since RBENV is used on the server I can run rbenv versions which shows me:

  system
* 2.1.2 (set by /var/www/mydomain.com/.rbenv/version)

那奇怪的地方 2.1.0 的来源以及如何确保我的服务器具有它所需的所有依赖项。

So where does that weird 2.1.0 come from and how can I make sure that my server has all the dependencies it requires.

推荐答案

我终于设法在新服务器上部署了我的应用程序。

I finally managed to deploy my application on the new server.

执行这些步骤是必需的。但是，由于我与之作战了几个小时，所以其中有些可能是多余的：

These steps were required to do it. However since I fought with it for a few hours some of it might be redundant:

• gem install bundler& & rbenv rehash ：这是必需的，因为 bundler 是我需要在Rails App上下文中外部的宝石之一


• 另一个是 gem install passenger&& rbenv rehash


• 我现在正在使用 https：/ /github.com/capistrano/rbenv ，但是为此我不得不从系统中删除RVM，这是我不太热衷的步骤。



• 我必须确保已创建当前符号链接，因此将其添加到 deploy.rb

• gem install bundler && rbenv rehash: This is required since bundler is one of the gems that I need outside of the Rails App context in terms of dependencies.
• Another one is gem install passenger && rbenv rehash
• I am now using https://github.com/capistrano/rbenv but for this I had to wipe RVM from my system, which was a step I wasn't too enthusiastic of doing.

• I had to make sure the current symlink was created so I added this to the deploy.rb

after 'deploy:set_current_revision', 'deploy:symlink:release'

我不得不删除一些共享目录：

I had to delete some of the shared directories:

rm -fr bin
rm -fr shared/bundle/
rm -fr bundle
