Failed to extract git version from ' git --version ' xcrun: error: invalid active developer path

cocopads更新库时失败，报错Failed to extract git version from ' git --version ' xcrun: error: invalid active developer path

最近 升级了一下电脑系统 macOSMojave 10.14.1

顺便升级了一下 Xcode Version 10.1 (10B61)

哭了 使用 cocosPods  集成时 报错

Mac:~mac$ pod-versionTraceback(most recent call last):5:from/usr/local/bin/pod:23:in`

分析：

Failed to extract git version from ' git --version ' xcrun: error: invalid active developer path

未能从git—version中提取 git 版本: 错误: 无效的活动开发路径；简单来说就是Git工具不好使了。

通常做法就是打开 terminal 执行 xcode-select --install

但由于我是 macOS 升级 所以这样是不行的，需要到 Git 官网下载 Git 才可以：

https://git-scm.com/download/mac

下载完成后手动安装 git 这样就可以解决了 ！

！！！以上方法网慢始终下载失败，最后在终端直接打这个命令执行完安装就ok了

命令行执行: xcode-select --install解决问题 . 重要的话说三遍!!!
