我尝试在我的 mac 上进行 2.2.3 flutter 升级，但现在我因为这个错误而无法运行
我试过brew link --overwrite cocoapods
但未检测到指挥官
zsh: command not found: brew
我也害怕升级 cocoapods，因为我测试了 flutter null 安全迁移，但如果我不成功，我会回到以前的工作版本（flutter 和 cocoapods）。
这是我的错误：

[!] CocoaPods could not find compatible versions for pod "Firebase/Firestore":
In snapshot (Podfile.lock):
Firebase/Firestore (= 7.3.0)
In Podfile:
cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`) was resolved to 2.4.0, which depends on
Firebase/Firestore (= 8.3.0)
Specs satisfying the `Firebase/Firestore (= 7.3.0), Firebase/Firestore (= 8.3.0)` dependency were found, but they required a higher minimum deployment target.
