我在rails gem文件中添加了gem'bitfinex-rb'，当我进行捆绑安装时，我得到了下面提到的错误：
Bundler could not find compatible versions for gem "faraday":
In snapshot (Gemfile.lock):
faraday (= 0.14.0)
In Gemfile:
bitfinex-rb was resolved to 0.1.0, which depends on
faraday (>= 0.9.2, ~> 0.9.2)
kucoin was resolved to 0.1.1, which depends on
faraday (>= 0.13)
Running `bundle update` will rebuild your snapshot from scratch, using only the gems in your Gemfile, which may resolve the conflict.
我尝试运行捆绑包更新，但没有运气，给出以下错误。

我尝试删除 Gemfile.lock 并安装捆绑包，但出现上述长列出的错误。对于这种情况，解决方案是什么。谢谢大家。
这是因为 kucoin 0.1.1 需要法拉第>=0.13，而 bitfinex-rb 0.1.0 需要法拉第~> 0.9.2(所以>= 0.9.2 和 <= 0.10(。至少在Ruby Gems中没有更高版本的bitfinex-rb，因此您可以更新它。而另一个版本的kucoin(0.1.0(也需要法拉第>= 0.13。因此，由于依赖性，您不能同时安装两个gem(kucoin和bitfinex-rb(。捆绑包尝试解析依赖项，但它只能在可能的情况下执行此操作。
