警告：Bundler的运行版本早于造成锁定文件错误的版本

Question

[开发/测试时，我一直在控制台中收到此错误

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`.

这完全不是在阻止我，而是在烦我。我知道最简单的解决方案就是将我的Gemfile.lock更新为此。

BUNDLED WITH
   2.1.2

但是我想永久解决。我尝试

gem uninstall bundler

然后

gem install bundler -v 2.1.4

让我一直给这个错误

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

并且当我尝试先安装2.1.4然后删除bundler 2.1.2控制台时，会显示以下输出。

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

这个问题有解决方案吗？在此先感谢

Answer 1

您应该将2.1.4作为默认gem安装，以便能够卸载2.1.2：

gem install bundler -v 2.1.4 --default

然后：

gem uninstall bundler -v 2.1.2
