無法構建不同版本的gem本機擴展ruby racer gem

Question

我從生產中複製了該應用程序，並進行了bundle install以安裝生產版本中而不是本地機器上的所有缺失gem。

Gem.lock文件具有rubyracer版本'0.10.1'。所以，當它試圖使用捆綁安裝安裝此版本時出現以下錯誤。

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /home/user/.rvm/gems/ruby-1.9.3-p392/gems/therubyracer-0.10.1 for inspection.

由於出現此錯誤，我無法在本地計算機的生產版本代碼上運行腳手架命令。請幫助我。

我們可以編輯gemfile.lock以刪除「therubyracer（0.10.1）」，然後運行命令generate scaffold，然後在使用生成腳手架後放回更改嗎？

Answer 1

在響應以下報價：

我們可以編輯Gemfile.lock的刪除 「therubyracer（0.10.1）」

無我們不可以。依賴於你對你有怎樣OS能夠做到以下幾點：

$gem uninstall libv8 
$gem install therubyracer 

我有我最近做了一個Rails應用程序，我也被走行軌3.2.14，並執行以下操作：

group :assets do 
    gem 'therubyracer', :require => 'v8' 
    gem 'less-rails' 
    gem 'coffee-rails', '~> 3.2.1' 

    # See https://github.com/sstephenson/execjs#readme for more supported runtimes 
    # gem 'therubyracer', :platforms => :ruby 

    gem 'uglifier', '>= 1.0.3' 
end 

如果在將此資產塊添加到您的gem文件之前，請使用第二種方法。 刪除您Gemfile.lock，然後將資產塊添加到Gemfile中，保存和運行bundle update
