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:

首先,检查您正在使用的Ruby版本。

$ruby -v
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin18]
$ which ruby
usr/bin/ruby

现在使用Homebrew安装最新的Ruby。

$ brew install ruby
==> ruby
By default, binaries installed by gem will be placed into:
/usr/local/lib/ruby/gems/2.7.0/bin

You may want to add this to your PATH.

ruby is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

如果你需要在PATH运行中先使用ruby:

$ echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> /Users/xxx/.bash_profile

为了让编译器找到ruby,你可能需要设置:

$ export LDFLAGS="-L/usr/local/opt/ruby/lib"
$ export CPPFLAGS="-I/usr/local/opt/ruby/include"

按照说明设置PATH。现在您将看到已安装的Ruby。确保将“xxx”替换为您的用户名。

$ echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> /Users/xxx/.bash_profile
$ echo 'export LDFLAGS="-L/usr/local/opt/ruby/lib"' >> ~/.bash_profile
$ echo 'export CPPFLAGS="-I/usr/local/opt/ruby/include"' >> ~/.bash_profile

$ source ~/.bash_profile

最后,确保PATH已经就位。

$ ruby -v
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin18]
$ which ruby
/usr/local/opt/ruby/bin/ruby

你可以开始了!确保按照如下方式指定保存目的地进行安装。

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

其他回答

我也有同样的问题。这可能是因为您的计算机使用的是较旧版本的ruby。所以你需要先更新你的ruby。我的工作在ruby 2.6.3版本

你需要首先打开终端,并把这段代码

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

然后输入这条命令

rvm install ruby-2.6.3

这将为您安装ruby,如果它还没有安装。在此之后,只需将ruby更新到新版本

rvm use ruby-2.6.3

在此之后,将ruby 2.6.3设置为默认值

rvm --default use 2.6.3

这可能会解决你的问题。现在可以输入命令

sudo gem install cocoapods

命令

pod setup

有时候问题是你的xcode工具版本太低了。如果您还没有尝试运行这些命令

sudo rm -rf /Library/Developer/CommandLineTools

xcode-select——安装

Sudo xcodebuild -许可接受

打开/图书馆/开发/ CommandLineTools /包/ macOS_SDK_headers_for_macOS_10.14.pkg

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。

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

当在iOS目录下运行pod install后试图在Flutter应用程序中设置GoogleMaps时,出现了同样的初始问题。

运行pod安装时出现以下错误:

zsh: /usr/local/bin/pod: bad interpreter: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: no such file or directory

接下来,在运行sudo gem install cocoapods之后,会导致另一个类似于error: error installing cocoapods: error: Failed to build gem native extension的错误。

ERROR:  Error installing cocoapods:
    ERROR: Failed to build gem native extension.

kevin建议安装Xcode开发工具:

xcode-select --install

在强调需要安装工具时,系统在运行pod install命令时再次产生与以前相同的错误。

通过拆卸和重新安装来刷新工具成为了下一个目标。 使用以下命令移除工具:

rm -rf /Library/Developer/CommandLineTools

再次安装xcode开发工具,使用:

xcode-select --install

然后,sudo gem install cocoapods和pod install运行成功。
