配置Flutter的ios环境卡了很久,简单记录一下踩的坑和最后的解决方案
首先需要安装Xcode(这一步基本没啥问题)
安装完Xcode之后再次执行 flutter doctor 提示安装CocoaPods,然后麻烦的问题就来了
安装gem 改ruby依赖源等都很简单,最后卡在sudo gem install cocoapods这条命令上,直接执行提示目录权限不够,加上--system会报错gem版本太低,更新gem又会提示依赖库需要更高的ruby版本,以及各种依赖版本报错等...
当前系统默认的ruby版本v2.3.3 gem版本v1.6
尝试了一些stackoverflow上的解决方案但是没有成功,例如下边的:
sudo gem install -n /usr/local/bin cocoapods
最终解决的过程
1.安装Rvm(RVM是一个命令行工具,可以提供一个便捷的多版本 Ruby 环境的管理和切换)
$ curl -L https://get.rvm.io | bash -s stable
2.载入环境变量
$ source ~/.bashrc
$ source ~/.bash_profile
3.rvm安装ruby环境
$ rvm install 2.2.4
4.设置为默认版本
$ rvm use 2.2.4 --default
5.再次执行cocoapods安装报了openssl的错误于是用RVM升级Ruby
$ rvm install ruby
最终环境
ruby 2.6.3p62
gem 3.0.8
执行sudo gem install cocoapods直接成功,无异常
flutter doctor -v
