swift - mac 更新到 Catalina 后 Podfile 不会更新，原因：找不到图像

问题描述

我最近将我的 mac 更新为 Catalina，因为当我尝试安装/更新它（Podfile）时，我的一个项目的 Podfile 崩溃了。

Traceback (most recent call last):

我从这条回溯消息中了解到，其中一个文件的引用不正确，但我不确定如何解决这个问题。我尝试将我的 Podfile 归结为基本要素，但错误仍然存​​在。这是 Pod 文件：

# Uncomment the next line to define a global platform for your project
platform :ios, '13.2'
target 'ShoeSwiperMenus' do
end

我尝试按照这个逐步的过程，认为它可能会有所帮助，但它没有。

运行时sudo gem install cocoapods，我收到以下错误：

ERROR:  Loading command: install (LoadError)
        dlopen(/usr/local/Cellar/ruby/2.5.3/lib/ruby/2.5.0/x86_64-darwin17/openssl.bundle, 9): Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib

ERROR:  While executing gem ... (NoMethodError)

任何帮助，将不胜感激！谢谢

解决方案

感谢@matt，我很快解决了这个问题。正如他所指出的，我的红宝石坏了。这些是我为解决此问题而采取的步骤：

安装 Ruby 版本管理器 rvm：curl -L https://get.rvm.io | bash -s stable

安装最新版本的 Ruby：rvm install ruby-[version] 在我的例子中是：rvm install ruby-2.7

然后：rvm use ruby-2.7

和：

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