我试图将cocoapods安装到运行OSX 10.9.1(新Mavericks)的MacBook Pro上,键入gem install cocoapods后,我得到以下错误:

在2020年为我工作(Mac OS Catalina)

xcode-select --install

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

其他回答

你需要安装Xcode的开发工具。最简单的方法是通过终端(这个问题)

xcode-select --install

我也遇到了同样的问题,尽管我使用的是最新版本的xcode命令行工具。

如果你安装了自制程序,请安装apple-gcc42。这立刻解决了我的问题。

如果你没有Homebrew,请先安装:https://brew.sh/index_pt-br

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

其次,如果你没有ruby,安装它: https://www.ruby-lang.org/pt/documentation/installation/

brew install ruby

你也可以按照这些步骤:https://gist.github.com/monicao/d372716cdfbb7e9cf692

然后,关闭终端,重新打开。

始终使用sudo安装cocoapods:

sudo gem install cocoapods

我的配置中有多个环境,这导致了问题,因为rvm会干扰安装。曾经的红宝石2。检测到X,安装正常。

对于我的环境,我做了以下工作: 1. xcode-select——安装 2. rvm implode(注意-太激烈了-你可能不需要这样做,我对旧的ruby安装没有任何用途,我通过rvm uninstall逐个删除它们,然后使用rvm implode 3.Gem安装cocoapods

这一次,最后一个命令运行正常,没有任何问题。

打开终端

xcode-select --install
sudo xcodebuild -license accept
curl -L https://get.rvm.io | bash -s stable

关闭及重开终端机

rvm install ruby-2.6

sudo gem install cocoapods
pod install 

在android studio上右键单击项目左上角,然后在Xcode中单击Flutter ->打开IOS模块
