Xcode 8命令行工具丢失(Git，Clang等) [英] Xcode 8 Command Line Tools Missing (Git, Clang, etc)

问题描述

两天前，我升级到了OSX Sierra.之后，我的开发工具似乎运行良好.

Two days ago, I upgraded to OSX Sierra. My development tools seemed to be working fine after that.

但是，今天我升级了Xcode 7.3.1-> 8.1，以使某些功能适用于React-Native开发.确切地说，我删除了7.3.1并重新安装了8.1.那是灾难开始的地方.

However, today I upgraded Xcode 7.3.1 -> 8.1 to make certain features work for React-Native development. To be precise, I deleted the 7.3.1 and installed 8.1 anew. That is where the woes had started.

尤其是，似乎大多数命令行工具都已消失.尝试使用git以及其他命令时出现错误.从.dmg文件安装后，我能够恢复Git.

In particular, it seems that most of the Command Line Tools are gone. I get errors when trying to use git as well as other commands. I was able to get Git back after installing from .dmg file.

我也尝试使用xcode-select --install安装命令行工具无济于事.安装继续进行，但是之后没有任何工具可用.

I have also tried installing Command Line Tools using xcode-select --install to no avail. Installation proceeds, but none of the tools become available afterwards.

作为正在发生的事的一个示例，以下是我在运行时收到的错误:curl -sSL https://get.rvm.io | bash -s stable --ruby

As an example of what is happening, the following are the errors I receive when running: curl -sSL https://get.rvm.io | bash -s stable --ruby

xcodebuild: error: SDK "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator9.3.sdk" cannot be located.
gcc: error: unable to find utility "gcc", not a developer tool or in PATH
configure: error: clang version 3.0 or later is required

有人知道这个问题可能是什么以及如何在Sierra + Xcode 8.1上设置开发环境吗?

Does someone know what the issue might be and how one goes about getting the development environment set up on Sierra + Xcode 8.1?

推荐答案

在安装新版本的Xcode后发生此错误.

This error occurred after installing the new version of Xcode.

重新启动对我有帮助.有时，即使退出并重新启动终端也可能有帮助.

Just restarting helped for me. Sometimes, even quitting and restarting Terminal might also help.
