Bundler无法找到兼容版本的宝石，尽管它在那里？

I don't understand this error I receive when I run bundle install:

我不明白运行bundle install时收到的这个错误:

Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    rails (= 3.0.0) was resolved to 3.0.0, which depends on
      bundler (~> 1.0.0)

  Current Bundler version:
    bundler (1.16.2)
This Gemfile requires a different version of Bundler.

If I have bundler version 1.16.2, why is it not considered to meet the ~> 1.0.0 criteria?

如果我有捆绑版本1.16.2,为什么不考虑满足〜> 1.0.0标准?

The ~> notation allows for the delineation of the incrementation whereby the least significant digit is allowed to differ from the specification.

〜>表示法允许描绘增量,从而允许最低有效数字与规范不同。

So in this case ~> 1.0.0 means any version that is >= 1.0.0 and < 1.1.

所以在这种情况下〜> 1.0.0表示任何版本> = 1.0.0且<1.1。

However a notation of ~> 1.0 would mean any version >= 1.0 and < 2.0

但是,〜> 1.0的符号表示任何版本> = 1.0且<2.0

In your case 1.16.2 is clearly greater than 1.1 and thus fails the requirement set forth

在你的情况下,1.16.2明显大于1.1,因此未达到规定的要求
