RN IOS环境搭建

iOS 安装CocoaPods

1、升级Ruby环境

sudo gem update –system

如果失败

ERROR:  While executing gem ... (Errno::EPERM)
    Operation not permitted @ rb_sysopen - /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/gem

则执行
sudo gem install -n /usr/local/bin cocoapods

2、更换Ruby镜像

首先移除现有的Ruby镜像

终端输入：gem sources –remove https://rubygems.org/

然后添加国内最新镜像源（淘宝的Ruby镜像已经不更新了）

终端输入：gem sources -a https://gems.ruby-china.com/

执行完毕之后输入gem sources -l来查看当前镜像
终端输入：gem sources -l

*** CURRENT SOURCES ***

https://gems.ruby-china.com

3、安装CocoaPods

终端输入：sudo gem install cocoapods

如果出现：

While executing gem ... (Gem::FilePermissionError)
   You don't have write permissions for the /usr/bin directory.

改为 sudo gem install -n /usr/local/bin cocoapods

4.pod切换源

查看源

终端输入： pod repo

执行：

git clone https://git.coding.net/CocoaPods/Specs.git ~/.cocoapods/repos/master

时间有点久

最后切记要：

pod repo update

master
- Type: git (master)
- URL:  https://git.coding.net/CocoaPods/Specs.git
- Path: /Users/leiming/.cocoapods/repos/master

主要是clone https://chromium.googlesource.com/webm/libwebp/ 这个google的git地址出的错(并且我开的全局模式的代理软件也无效)

解决方法:

Finder -> 前往文件夹 (⇧⌘G) -> ~/.cocoapods/repos/master/Specs/1/9/2/libwebp

选择最新版本 进入 libwebp.podspec.json

把https://chromium.googlesource.com/webm/libwebp 替换为 https://github.com/webmproject/libwebp.git 并保存

接着pod install
