如下所示，libv8安装正常，但是therubyracer无法安装。我使用的是Mac 10.7.4。

您可以使用来自brew而不是gem的Libv8。您可以通过以下命令实现：

$ gem uninstall libv8
$ brew install v8
$ gem install therubyracer
如果您需要安装特定版本的therubyracer，请在此处指定。使用以下命令：gem install therubyracer -v '0.11.4' （替换版本号），而不是 gem install therubyracer。 - aaron-coding
也适用于我。 - Pascal

@Haegin在https://github.com/cowboyd/libv8/issues/205中的回答。

brew uninstall v8
brew install v8-315
gem uninstall -a libv8
gem uninstall -a therubyracer
gem install libv8 -v '3.16.14.17' -- --with-system-v8
gem install therubyracer -v '0.12.2' -- --with-v8-dir=$(brew --prefix v8-315)
我寻找了几种解决这个问题的方法，而这是唯一一个在我的 macOS Monterey 上有效的。谢谢。 - maurymmarques

为了一个老的项目，我不得不在Mavericks上使用0.10.1版本的rubyracer（bootstrap依赖它）。因此，我必须使用旧版本的gcc。
1. 编辑你的.zshrc或.bashrc文件。
export CC=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2
export CXX=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/g++-4.2
export CPP=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/cpp-4.2

  • 请确保您已卸载所有旧版本的libv8

    • gem uninstall libv8

  • 安装您的therubyracer版本

    • gem install therubyracer -v=0.10.1

    对于Linux操作系统：

    以下代码当然是正确的：

    $ gem uninstall libv8

    $ gem install therubyracer

    但有时这并不能解决问题，因为您没有安装make程序。 首先，您需要安装make。要做到这一点，请运行以下命令：

    sudo apt-get install build-essential

    只有在此之后才能运行以下命令：

    gem install therubyracer

    谢谢！这是解决我所有问题的答案。 - Albert Català

    在 Mavericks 上，您只需要更新到 therubyracer 0.12.0 版本。

    这些步骤适用于我的情况：
    1. 卸载 v8： brew uninstall v8 2. 安装 v8-315： brew install v8-315 3. 卸载 libv8： gem uninstall -a libv8 4. 卸载 therubyracer： gem uninstall -a therubyracer 5. 安装 libv8 版本为 '3.16.14.19'，并添加参数 '--with-system-v8'： gem install libv8 -v '3.16.14.19' -- --with-system-v8 6. 安装 therubyracer 版本为 '0.12.3'，并添加参数 '--with-v8-dir=$(brew --prefix v8-315)'： gem install therubyracer -v '0.12.3' -- --with-v8-dir=$(brew --prefix v8-315)
    谢谢，这个可行：MacOS BigSur、rbenv、ruby 2.5 - 0bserver07

    对于我的Mac 10.10.5和Ruby 2.1.0，以下方法适用：

    gem uninstall libv8
gem uninstall therubyracer

brew upgrade gcc
brew install v8

bundle config --local build.libv8 --with-cxx=/usr/local/bin/gcc-6
gem install libv8 -v '3.16.14.17' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8-315

bundle install # worked !

    我的解决方案是将这些步骤应用于10.7.4。
    export CC=gcc-4.2

sudo ln /usr/bin/gcc /usr/bin/gcc-4.2

gem uninstall libv8
gem install therubyracer

    安装v8：

    brew install v8@3.15

    安装 gem libv8 后：
    gem install libv8 -v 3.16.14.19 -- --with-system-v8

    安装特定版本的therubyracer：

    gem install therubyracer  -v '0.12.3' -- --with-v8-dir=/usr/local/opt/v8@3.15
