flutter ios上踩的一个坑

在ios模拟器上调试的时候出现错误信息：The iOS Simulator deployment target is set to 4.3...

原来是因为ios 版本问题，于是找到资料是在 Podfile文件中添加判断

post_install do |installer|
  installer.pods_project.targets.each do |target|
 target.build_configurations.each do |config|
  if config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'].to_f < 8.0
    config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '8.0'
     end
   end
  end
end

接着又报错，Using new build systemnote: Planning buildnote

查资料原来是要升级 cocospod，于是百度了下，

1. 检测gem版本

 

$ gem -v

如果gem版本小于2.6.x,则需要更新gem

2. 更新gem(gem版本高于2.6.x可跳过此步)

1. 检测ruby源,更新gem需要官方的ruby源

 

$ gem sources -l

1. 替换ruby源为官方地址(如果ruby源是"https://rubygems.org/"则跳过此步)

 

$ gem sources --add https://rubygems.org/ --remove xxx.xxx

1. 确保ruby源中只有"https://rubygems.org/"

 

$ gem sources -l

1. 更新gem(此步要)

 

$ gem update --system

1. 查看gem版本,确认大于2.6.x

 

$ gem -v

1. 将ruby源切换回国内的

 

$ gem sources --add https://gems.ruby-china.com/
 --remove https://rubygems.org/

1. 确保只有"https://gems.ruby-china.com/"一个ruby源

 

$ gem sources -l

3. 更新cocoapods

 

$ gem install cocoapods -n /usr/local/bin

结果还是不行

xcode报错：

Xcode's output:
↳

    #import
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

android也报错，最后看有人说是因为版本问题，建议换个插件。

目前使用的插件是：

image_gallery_saver: ^1.2.2
permission_handler: ^4.2.0+hotfix.3
