Flutter搭建环境遇坑之一：ios cocoapods not install遇坑背景本人从github http

遇坑背景

遇到的问题

研究一下flutter ios端，导入已有的flutter时，升级了下xCode app （Version 14.3.1 (14E300c)）后，ios项目运行编译报错如下：

Dart Warning: CocoaPods minimum required version 1.10.0 or greater not installed. Skipping pod install. CocoaPods is used to retrieve the iOS and macOS platform side's plugin code that responds to your plugin usage on the Dart side. Without CocoaPods, plugins will not work on iOS or macOS. For more info, see flutter.dev/platform-pl… To upgrade see guides.cocoapods.org/using/getti… for instructions. CocoaPods not installed or not in valid state. Error launching application on iPhone 14 Pro Max. #根据输入日志错误分析如下： CocoaPods minimum required version 1.10.0 or greater not installed.

意思是未安装CocoaPods最低要求版本1.10.0或更高版本。

问题分析猜测

打开CocoaPods Guides，sudo gem install cocoapods 一直报没权限，加上gem install cocoapods --user-install` 后报安装成功了，但是flutter doctor还是显示没安装，stackoverflow上大概都是

1. uninstall

2. install

3. flutter clean

4. flutter pub get

5. 重启IDE

6. flutter fun

以上全部不管用。

还有一个声音，是使用homebrew，brew install --cask cocoapods 依然卡住。链接如下。

很神奇，gem里的是1.12.1，而为什么显示的是1.12.1呢？需要注意的是，刚才homebrew下载的是 github.com/CocoaPods/C… github.com/CocoaPods/C… （1.12.1）。所以，为什么人们都说用cocoapods很难搞，这里可能看出 homebrew里用的是旧版本，而gem里是新的版本。

结合上述链接描述，我先后逐步分析了安装路径是否正确，homebrew中的cocoapods是否是最新版本，查看环境配置情况。果然发现是pod和cocoapods没有配置环境变量导致的。

解决方案步骤如下：

1.首先卸载掉旧版本的homebrew中的cocoapods，因为它是错误的版本

2.通过gem which cocoapods

Dart yp-220608@YP-220608deMacBook-Pro ~ % gem which cocoapods /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/universal-darwin22/rbconfig.rb:21: warning: Insecure world writable dir /opt/homebrew/bin in PATH, mode 040777

把pod和cocoapods加入到环境变量里

Dart export PATH=" $PATH:$ HOME/.local/share/gem/ruby/2.6.0/bin/:$HOME/.local/share/gem/ruby/2.6.0/gems/cocoapods-1.12.1/lib/cocoapods.rb"

4.source ~/.zshrc (maybe .bashrc )

5.运行flutter doctor命令查看环境配置情况
