CommandLineTools' - RN

简要说明,此次尝试安装 ReactNative 时当前 MacPro 版本为 10.13.6、Xcode 版本为 Version 9.4.1 (9F2000),按照官方的完整原生环境搭建流程一步步执行,可不料刚开始就遇到了一个很大的难关,具体如下:

官方推荐使用 Homebrew 来安装,随后便顺理成章的进入了 Homebrew 的主页,醒目的看到了 Install Homebrew 的标语,随后果断打开终端,执行了"/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)""命令;

可不料稍等片刻后便进入了尴尬的处境,很直截了当的抛出了异常,随后在强大的度娘中各种搜罗解决版本,仍以失败告终.

异常如下:

Xcode-select: error: invalid developer directory ‘/Library/Developer/CommandLineTools’
Failed during: /usr/bin/sudo /usr/bin/xcode-select –switch /Library/Developer/CommandLineTools

尝试解决办法如下:

1.xcode-select --install (现版本 Xcode 安装时便已经同步安装好了)

2.同时 Preferences -> Locations 下的 Command Line Tools 也是默认配置好的

3.sudo xcode-select --switch /Library/Developer/CommandLineTools/

sudo xcode-select -p 修改路径这招经过尝试也是然并卵

最终通过修改其安装 Homebrew 的脚本 code 指令后,越过了"/Library/Developer/CommandLineTools/" 验证这一环节,因为如上所说,在安装 Xcode 的同时它自身已经将其安装成功,故直接跳过此重新验证的步骤,直接执行后续操作.

在具体操作前,先说两个注意事项:

其一,使用如下方法的首要前提条件是您当前设备已经安装好了 Xcode;

其二,执行如下脚本后,依然会提示 xcode-select --install 中的安装提示,弹出提示框后直接点击取消按钮即可,因为条件一中的条件已经事先满足.

随后便可以执行后续操作.

具体操作如下:

首先,通过终端找到其脚本的存储位置(cd、ls 这样的操作,大家都应该很顺手了);

其次,执行该脚本 ruby installHomebrew;

再其次,稍事等待便会弹出如上所说的 Xcode 确认提示框,直接取消掉就 ok;

最后,继续等待片刻,Homebrew 它便会自动执行完毕,安装完成后继续根据 ReactNative 官网执行后续操作即可;

后续操作从 brew install node 开始一步步往下按步骤走,最终便大功告成!
