ios - 安装 Ruby gem 'cocoapods' 失败

Question

我尝试将 cocoapods 合并到我的 fastlane 构建中。根据应该像在我的 Fastfile 中添加一行一样简单的文档：

cocoapods

这应该会打电话pod install给我。但情况似乎并非如此。而不是仅仅调用pod installfastlane 尝试安装 cocoapods ，然后失败：

[16:32:36]: Installing Ruby gem 'cocoapods'...

特别奇怪的是：cocoapods 已经安装好了：

>which pod                   
/usr/local/bin/pod

无需安装。如前所述，文档没有说明这一点。任何提示或指针。

更新 1：

注意到一些有趣的事情。打电话时fastlane env我得到：

| Key                         | Value                                                                |

但实际安装的摩擦是：

>ruby --version
ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-darwin19]

看起来 fastlane 使用了错误的 ruby​​。
