替换ruby源

$ gem sources
*** CURRENT SOURCES ***

http://rubygems-china.oss.aliyuncs.com

这个数据源已经失效了,我们移除掉

$ gem sources -r http://rubygems-china.oss.aliyuncs.com
http://rubygems-china.oss.aliyuncs.com removed from sources

加入新的数据源,目前只有ruby-china的源是保持更新的

$ gem sources -a https://gems.ruby-china.org/
https://gems.ruby-china.org/ added to sources

确保当前只有一个ruby源

$ gem sources
*** CURRENT SOURCES ***

https://gems.ruby-china.org/

ERROR: While executing gem ... (OpenSSL::SSL::SSLError) hostname "upyun.gems.ruby-china.org" does not match the server certificate

$ gem update --system
Updating rubygems-update
ERROR:  While executing gem ... (OpenSSL::SSL::SSLError)
    hostname "upyun.gems.ruby-china.org" does not match the server certificate

解决方案

• 在这里下载ruby源码点击下载,并解压
• 安装openssl

$ brew install openssl

如果提示

Warning: openssl 1.0.2l is already installed

说明已经安装了openssl

• cd到解压好的ruby源码文件夹中
• 配置源码（此处需要添加openssl目录索引）

$ ./configure --with-openssl-dir=/usr/local/ssl

• 编译ruby源码

$ make

• 最后安装ruby

$ sudo make install

error: RPC failed; curl 56 SSLRead() return error -36

[!] /usr/bin/git clone https://github.com/CocoaPods/Specs.git master
Cloning into 'master'...
error: RPC failed; curl 56 SSLRead() return error -36
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed

解决方案

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

注意

1. "/Applications/Xcode.app/Contents/Developer"此路径是当前默认XCode的所在位置,如果安装了多个XCode需要多加注意
2. 做了以上操作之后还会报错,将XCode删除,重新安装

PS
获取当前XCode路径,在终端中输入

$ xcode-select --print-path

问题描述
同事pod新库之后合并代码,我这边拉下来之后重新pod install报错

解决方法

1. 选中 项目名称–>Target–>项目名称–>General–>Linked Frameworks and Libraries–>选中 libpods-项目名称.a 去除掉这个 .a
2. 然后再一次 pod install
3. 如果出现pod下面没有文件,就把Xcode关掉重新打开就好了
