颤振医生 - CocoaPods 已安装但无法正常工作

Question

使用 zsh - 用于在 bash
brew doctor 中工作 - 您的系统已准备好进行 brew 。
颤振医生给出了这个错误

[!] Xcode - develop for iOS and macOS (Xcode 12.2)
    ? CocoaPods installed but not working.
        You appear to have CocoaPods installed but it is not working.
        This can happen if the version of Ruby that CocoaPods was installed with is different from the one being used to invoke it.
        This can usually be fixed by re-installing CocoaPods. For more info, see https://github.com/flutter/flutter/issues/14293.
      To re-install CocoaPods, run:
        sudo gem install cocoapods  

sudo gem 安装 cocoapods

Gives this error  
dyld: Library not loaded: /usr/local/opt/gmp4/lib/libgmp.3.5.2.dylib  
  Referenced from: /Users/puser/.rvm/rubies/ruby-2.5.1/bin/ruby  
  Reason: image not found  
zsh: abort      sudo gem install cocoapods  

我无法纠正上述错误 - 有什么建议吗？

        if [[ -n "${rvm_prefix:-}" ]] && ! [[ "$HOME/.rvmrc" -ef "${rvm_prefix}/.rvmrc" ]]
        then

Answer 1

使用酿造和宝石

1. 首先通过gem卸载

   sudo gem 卸载 cocoapods

2. 通过brew安装cocoapods

   酿造安装cocoapods

3. 使用brew链接

   酿造链接——覆盖cocoapods

Answer 2

使用这篇文章的建议，我能够在安装 cocoapods 时使用以下命令重新
安装 cocoapods gem native extension error

打开终端

curl -L https://get.rvm.io | bash -s stable

重新打开终端

rvm install ruby-2.6

rvm use ruby-2.6.5

rvm --default use 2.6.5

然后这按预期安装了 cocoapods

sudo gem install cocoapods

Answer 3

首先安装brewMac 版的包管理器。 https://brew.sh

如果您使用 macOS，不建议使用系统 Ruby。你不应该使用它。它供系统特定使用。您需要为用户安装另一个。

brew install rbenv

然后安装最新版本的ruby。今天是 3.1.0

rbenv install 3.1.0 --verbose

然后设置要在所有 shell 中使用的 Ruby 全局版本

rbenv global 3.1.0

关闭终端并再次重新打开它，以影响更改。

最后安装cocoapods

gem install cocoapods

如您所见，您不使用sudo命令。因为您没有覆盖系统特定的配置。当你需要使用sudo命令时意味着你正在做一些你应该避免的事情。

如果您正在使用fastlane并且仍然抱怨cocoapods，即使cocoapods安装正确，请fastlane再次重新安装：

brew uninstall fastlane
gem install fastlane

如果您在构建 3.1.0 时遇到 ruby​​ zlib 扩展问题：

1. brew install zlib
2. LDFLAGS=-L/usr/local/opt/zlib/lib CPPFLAGS=-I/usr/local/opt/zlib/include rbenv install 3.1.0
