ruby-on-rails - 警告 : the running version of Bundler is older than the version that created the lockfile error

Question

在开发/测试时，我的控制台中不断出现此错误

Warning: the running version of Bundler (2.1.2) is older than the version that created the lockfile (2.1.4). We suggest you to upgrade to the version that created the lockfile by running `gem install bundler:2.1.4`.

它根本没有阻止我，而是在打扰我。我知道最简单的解决方案就是将我的 Gemfile.lock 更新为这个。

BUNDLED WITH
   2.1.2

但我想永久解决这个问题。我试着

gem uninstall bundler

进而

gem install bundler -v 2.1.4

它让我一直给这个错误

Gem bundler-2.1.2 cannot be uninstalled because it is a default gem

当我尝试首先安装 2.1.4 然后删除 bundler 2.1.2 控制台给我这个输出。

Gem bundler-2.1.2 cannot be uninstalled because it is a default gem
Successfully uninstalled bundler-2.1.4

这个问题有什么解决办法吗？提前致谢

Answer 1

就跑 gem install bundler:2.1.4 ，不用担心ruby自带的老版本，应该不会用的。
