昨天晚上升级了CocosPads1.0, 只是安装成功了，现在项目里面运行pod install又发现了几个问题，昨天折腾的太晚了。今天继续折腾吧。
今天终于彻底搞定了CocosPods1.0，包括安装，运行和一个开源项目PodFile的1.0升级。
运行pod install时发现CocoaPods 提示有1.0版本了，于是打算升级一下。
CocoaPods 1.0.0 is available.
To update use: gem install cocoapods
结果就出现了下面的错误，分析了下原因是/usr/bin/xcodeproj目录路径错了，网上搜了下解决问题，使用sudo gem install -n /usr/local/bin cocoapods --pre 命令顺利安装成功。
$ sudo gem install cocoapods
ERROR: While executing gem ... (Errno::EPERM)
Operation not permitted - /usr/bin/xcodeproj
$ ls -al /usr/bin/xcodeproj
ls: cannot access /usr/bin/xcodeproj: No such file or directory
$ sudo gem install -n /usr/local/bin cocoapods --pre

Successfully installed molinillo-0.4.5
Fetching: cocoapods-try-1.0.0.gem (100%)

在项目下运行pod install 报错了：
od install

网上搜了下，发现这个issue已经close了，但好像没有更新啊，https://github.com/CocoaPods/CocoaPods/pull/5288
只好自己看代码修改一下：
修改 /Library/Ruby/Gems/2.0.0/gems/cocoapods-1.0.0/lib/cocoapods/sources_manager.rb
在第二行增加
require 'set'
保存文件，需要输入密码的。
继续运行pod install， 结果又报下面的错误：
edhita $ pod install
Re-creating CocoaPods due to major version update.
[!] `:head` dependencies have been removed. Please use normal external source dependencies (`:git => 'GIT_REPO_URL'`) instead of `:head` for `EDHFontSelector`.
这个看提示应该是个版本兼容问题了，还是先去仔细看看官方的CocoaPods 1.0的release说明吧。
应该是不支持:head这个语法了,并且必须有target。
下面用正在研究的markdown编辑器Edhita的Podfile做个升级的例子吧，
原地址 https://github.com/tnantoka/edhita/blob/master/Podfile
迁移前的代码：
platform :ios, "8.0"
source 'https://github.com/CocoaPods/Specs.git'
pod 'EDHFinder', '~> 0.1'
pod 'EDHFontSelector', :head
pod 'EDHInputAccessoryView', '~> 0.1'
pod 'Google-Mobile-Ads-SDK'
pod 'Colours', '~> 5.5'
pod 'FXForms', '~> 1.2'
pod 'GHMarkdownParser', '~> 0.1'
pod 'VTAcknowledgementsViewController', '~> 0.12'
pod 'Bootstrap', podspec: 'https://raw.githubusercontent.com/tnantoka/podspecs/master/Specs/Bootstrap/Bootstrap.podspec'
pod 'Megrim', podspec: 'https://raw.githubusercontent.com/tnantoka/podspecs/master/Specs/Megrim/Megrim.podspec'
pod 'github-markdown-css', podspec: 'https://raw.githubusercontent.com/tnantoka/podspecs/master/Specs/github-markdown-css/github-markdown-css.podspec'
post_install do |installer|
require 'fileutils'
FileUtils.cp_r('Pods/Target Support Files/Pods/Pods-acknowledgements.plist', 'Edhita/Assets/Pods-acknowledgements.plist')
end
升级到cocosPods 1.0后的代码
platform :ios, "8.0"
source 'https://github.com/CocoaPods/Specs.git'
target 'Edhita'
pod 'EDHFinder', '~> 0.1'
pod 'EDHFontSelector', '~> 0.1'
pod 'EDHInputAccessoryView', '~> 0.1'
pod 'Google-Mobile-Ads-SDK'
pod 'Colours', '~> 5.5'
pod 'FXForms', '~> 1.2'
pod 'GHMarkdownParser', '~> 0.1'
pod 'VTAcknowledgementsViewController', '~> 0.12'
# pod 'Bootstrap', podspec: 'https://raw.githubusercontent.com/tnantoka/podspecs/master/Specs/Bootstrap/Bootstrap.podspec'
# pod 'Megrim', podspec: 'https://raw.githubusercontent.com/tnantoka/podspecs/master/Specs/Megrim/Megrim.podspec'
# pod 'github-markdown-css', podspec: 'https://raw.githubusercontent.com/tnantoka/podspecs/master/Specs/github-markdown-css/github-markdown-css.podspec'
post_install do |installer|
require 'fileutils'
# FileUtils.cp_r('Pods/Target Support Files/Pods-Edhita/Pods-Edhita-acknowledgements.plist', 'Edhita/Assets/Pods-acknowledgements.plist')
end
我偷懒注释了一些不需要的代码，运行pod install, Xcode打开Edhita.xcworkspace, 就能编译通过了。效果如下

这次CocoaPods 1.0的升级体验还真是坑啊，经历了4年半的开发才发布1.0版本啊，不知道该说什么好了。
珍爱生命，新项目拥抱Carthage吧。但也不能不用CocoaPods啊，那么多开源项目都用了啊，还是暂时先不要升级1.0了。
