解決方案是執行:

pod repo update --verbose

再執行命令:

pod install

如果還是出錯,刪除podfile.lock檔案

如果還報錯就刪除 第三方庫的版本再次執行pod install就可以了

[!] The version of CocoaPods used to generate the lockfile (1.11.0) is higher than the version of the current executable (1.10.1). Incompatibility issues may arise.

[!] CocoaPods could not find compatible versions for pod "JMLink":

In snapshot (Podfile.lock):

JMLink (= 1.2.4)

In Podfile:

JMLink (= 1.2.4)

None of your spec sources contain a spec satisfying the dependencies: `JMLink (= 1.2.4), JMLink (= 1.2.4)`.

You have either:

* out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.

* mistyped the name or version.

* not added the source repo that hosts the Podspec to your Podfile.
