安装libv8时出错:错误:无法构建gem本机扩展
提问于 2013-10-30 12:15:52
我做了一个rails项目，
rails new test_bootstrap.成功。
已移至项目目录并添加了gem
gem "therubyracer"
gem "less-rails" #Sprockets (what Rails 3.1 uses for its asset pipeline) supports LESS
gem "twitter-bootstrap-rails"然后运行
bundle install在那之后，我就有了这个错误。

continue.
Make sure that `gem install libv8 -v '3.16.14.3'` succeeds before bundling.为一些韩国人感到抱歉。它说，它找不到选择的路径或类似的东西。
我试着运行这个命令
gem install libv8 -v '3.16.14.3' 抛出同样的错误。

如何解决libv8/therubyracer问题
我遇到了类似的问题，在安装libv8后，安装therubyracer时出错。以下是我的解决方案：
$ gem install libv8 -v '3.16.14.3' -- --with-system-v8
$ bundle install--请参阅安装therubyracer时出错--
$ gem uninstall libv8
$ brew install v8
$ gem install therubyracer
$ bundle install--请参阅安装libv8时出错--
$ gem install libv8 -v '3.16.14.3' -- --with-system-v8Stack Overflow用户

我尝试了上面列出的解决方案，该命令看起来非常适合安装单独的gem，但对于bundler用户，您应该使用包配置。
使用
bundle config build.libv8 --with-system-v8 和
bundle config build.therubyracer --with-system-v8配置bundler以获取安装特定gem时要使用的参数

使用homebrew，这可以帮助我解决这个错误。
brew tap homebrew/versions
brew install v8-315
gem install libv8 -v '3.16.14.13' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8-315
bundle install在rubyracer Github问题上见过。
对于作为homebrew /版本已被删除的homebrew的新版本：
brew install v8@3.15
gem install libv8 -v '3.16.14.13' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8@3.15
bundle install@gorner的建议(thx)
