一、Cocoapod 执行pod install命令时报错
[!] An error occurred while processing the post-install hook of the Podfile. no implicit conversion of nil into String /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/pathname.rb:349:in `initialize' /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/pathname.rb:349:in `new' /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/pathname.rb:349:in `+' /Library/Ruby/Gems/2.3.0/gems/xcodeproj-1.8.1/lib/xcodeproj/project.rb:103:in `open' /Users/xxx/Documents/WorkCode/DoorCamera/mihomeinternal/MiHome/SegmentPodfile/pre_and_post_install.rb:20:in `block in pod_pre_post_install' /Library/Ruby/Gems/2.3.0/gems/cocoapods-core-1.6.1/lib/cocoapods-core/podfile.rb:179:in `post_install!' /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.6.1/lib/cocoapods/installer.rb:701:in `run_podfile_post_install_hook' /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.6.1/lib/cocoapods/installer.rb:689:in `block in run_podfile_post_install_hooks' /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.6.1/lib/cocoapods/user_interface.rb:145:in `message' /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.6.1/lib/cocoapods/installer.rb:688:in `run_podfile_post_install_hooks' /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.6.1/lib/cocoapods/installer.rb:211:in `block in generate_pods_project' /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.6.1/lib/cocoapods/user_interface.rb:64:in `section' /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.6.1/lib/cocoapods/installer.rb:208:in `generate_pods_project' /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.6.1/lib/cocoapods/installer.rb:139:in `install!' /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.6.1/lib/cocoapods/command/install.rb:48:in `run' /Library/Ruby/Gems/2.3.0/gems/claide-1.0.2/lib/claide/command.rb:334:in `run' /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.6.1/lib/cocoapods/command.rb:52:in `run' /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.6.1/bin/pod:55:in `<top (required)>' /usr/local/bin/pod:23:in `load' /usr/local/bin/pod:23:in `<main>'
二、解决
这个原因是因为ruby的版本比较低导致的，需要更新ruby的版本
执行以下命令：
➜ MiHome git:(doorscamera) ✗ cd "$(brew --repo)" && git fetch && git reset --hard origin/master && brew update HEAD is now at b4f73e616 Merge pull request #6016 from jonchang/update-policy Already up-to-date. ➜ Homebrew git:(stable) rvm gemset empty default ➜ Homebrew git:(stable) rvm use 3 --default Required ruby-2.2.5 is not installed. To install do: 'rvm install "ruby-3"' ➜ Homebrew git:(stable) rvm gemset empty defaultrvm install "ruby-3 dquote> ➜ Homebrew git:(stable) rvm install "ruby-3"
重新安装ruby解决
