如何解决不同 gem 依赖项之间的冲突

让我们看看是否有人可以帮助我，我不知道自己在做什么。

该服务器是 debian 8.4，已完全更新。

我还使用“gem update”更新了宝石，所有可能的错误和警告都已修复。

我正在安装 redmine_git_hosting，发生了以下情况：

root@esplx345:/usr/share/redmine# bundle install --without development test
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break
this application for all non-root users on this machine.
Warning: this Gemfile contains multiple primary sources. Using `source` more than once without a block is a security risk, and may result in installing unexpected gems. To resolve this warning, use a block to indicate which gems should come from the secondary source. To upgrade this warning to an error, run `bundle config disable_multisource true`.
Your Gemfile lists the gem redcarpet (~> 3.3.2) more than once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the version of just one of them later.

Bundler could not find compatible versions for gem "rack":
  In snapshot (Gemfile.lock):
    rack (= 1.5.5)

  In Gemfile:
    rails (~> 4.1.4) was resolved to 4.1.15, which depends on
      actionpack (= 4.1.15) was resolved to 4.1.15, which depends on
        rack (~> 1.5.2)

    gitlab-grack was resolved to 2.0.0.pre, which depends on
      rack (~> 1.4.1)

    rack-openid was resolved to 1.4.2, which depends on
      rack (>= 1.1.0)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
root@esplx345:/usr/share/redmine#

我已经在 Google 上搜索过并尝试了很多方法，但似乎没有任何效果。

我的系统上有以下精华：

root@esplx345:/usr/share/redmine# gem update
Updating installed gems
Nothing to update
root@esplx345:/usr/share/redmine# gem list

非常感谢您的帮助。

答案1

当您拥有不同 Ruby 版本或 Rails 的不同项目时，使用 RVM 是一个很好的策略，但我通常只删除 Gemfile.lock 并运行bundle install，一切就正常运行。

答案2

我使用了 RVM

说明可在此处找到 =>http://redmine-git-hosting.io/how-to/install-redmine/#step-2-install-rvm

复制粘贴，以防它消失。

(step 2) Install RVM

Ruby Version Manager (RVM) is a command-line tool which allows you to easily install, manage, and work with multiple ruby environments from interpreters to sets of gems.

root# su - redmine
redmine$ gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
redmine$ curl -sSL https://get.rvm.io | bash -s stable
Be sure to have this in /home/redmine/.profile :

# Set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
  PATH="$HOME/bin:$PATH"
fi

# set PATH so it includes rvm bin if it exists
if [ -d "$HOME/.rvm/bin" ] ; then
  PATH="$PATH:$HOME/.rvm/bin"
fi

if [ -s "$HOME/.rvm/scripts/rvm" ] ; then
  source "$HOME/.rvm/scripts/rvm"
fi

if [ -s "$HOME/.rvm/scripts/completion" ] ; then
  source "$HOME/.rvm/scripts/completion"
fi
Now you should logout from Redmine user with exit then ‘relogin’ with su - redmine to reload env vars properly.
