找不到宝石捆绑器Ruby

Question

使用Mac OS 13，rbenv。

ruby 2.5.0p0（2017-12-25修订版61468）[x86_64-darwin17]

Rails 5.1.4

Bundler版本1.16.1

rbenv 1.1.1

我正在尝试启动一个新的Rails应用程序，然后得到这个：

据我所知，它与Ruby版本有关，但我不知道如何解决这个问题。

Answer 1

看起来您可能需要执行gem install bundler并获取bundler gem以启动并运行rails。

Answer 2

STEP（1）：安装bundler gem：

sudo gem install bundler

完成后，您应该收到类似这样的消息：

Fetching: bundler-1.16.1.gem (100%)
Successfully installed bundler-1.16.1
Parsing documentation for bundler-1.16.1
Installing ri documentation for bundler-1.16.1
Done installing documentation for bundler after 6 seconds
1 gem installed

步骤（2）：尝试检查捆绑器版本：

bundle -v

你应该得到这样的版本号：

Bundler version 1.16.1

STEP（3）：现在您可以使用bundle install：

bundle install

我希望我的回答有所帮助。
