Git Push to Rails Production 给出响应您的 Ruby 版本是 1.9.3，但是当 Ruby 版本是 2.2.2 时，您的 Gemfile 指定了 2.2.2

Question

我到处都看到了这个错误，但我找到的解决方案都没有帮助解决这个问题。我正在 Mac 上本地开发一个 rails 应用程序，并在 DigitalOcean 上设置了一个 droplet 来将应用程序推送到。我的 droplet 正在运行 Ubuntu 14，我正在使用 Git 接收后挂钩进行部署。这是钩子：

#!/bin/bash

GIT_DIR=/home/xxx/yyy_production
WORK_TREE=/home/xxx/yyy
export XXX_DATABASE_USER='xxx'
export XXX_DATABASE_PASSWORD='12345'

export RAILS_ENV=production
. ~/.bashrc

while read oldrev newrev ref
do
    if [[ $ref =~ .*/master$ ]];
    then
        echo "Master ref received.  Deploying master branch to production..."
        mkdir -p $WORK_TREE
        git --work-tree=$WORK_TREE --git-dir=$GIT_DIR checkout -f
        mkdir -p $WORK_TREE/shared/pids $WORK_TREE/shared/sockets $WORK_TREE/shared/log

        # start deploy tasks
        cd $WORK_TREE
        bundle install
        rake db:create
        rake db:migrate
        rake assets:precompile
        sudo restart puma-manager
        sudo service nginx restart
        # end deploy tasks
        echo "Git hooks deploy complete"
    else
        echo "Ref $ref successfully received.  Doing nothing: only the master branch may be deployed on this server."
    fi
done

这是我推送时得到的输出：

remote: rake aborted!
remote: Bundler::RubyVersionMismatch: Your Ruby version is 1.9.3, but your Gemfile specified 2.2.2

我完全不明白这一点，因为我已经安装了 ruby​​ 2.2.2 并使用 RVM 选择了它。当我使用 ssh 登录到 Ubuntu 机器时，我在运行 bundler 时没有遇到任何错误。然而，当我使用我的钩子运行时，这就是它所做的。我已经为此奋斗了好几天。非常感谢任何帮助。

在您的 droplet 和 mac 上，删除 Gemfile.lock，确保 ruby -v 响应版本 2.2，然后执行 bundle update。

这些步骤应该会重置一切。如果它们不起作用，请执行 spring stop 并重新安装 bundler binstubs（如果您使用这些工具）。

祝你好运！
