Question

我从生产中复制了应用程序并进行了捆绑安装，以安装生产版本中缺少的所有宝石，而不是我本地机器上的宝石。

Gem.lock文件的rubyracer版本为“0.10.1”。因此，当它尝试使用bundle install安装此版本时会出现以下错误。

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

由于此错误，我无法在本地计算机的生产版本的代码上运行脚手架命令。请帮帮我。

我们可以编辑gemfile.lock以删除“therubyracer（0.10.1）”，然后运行命令generate scaffold，然后在使用生成脚手架后放回更改吗？

回应以下引用：

我们可以编辑gemfile.lock来删除“therubyracer（0.10.1）”

不，我们不能。根据您所使用的操作系统，您可以执行以下操作：

$gem uninstall libv8 
$gem install therubyracer

我有一个我最近做过的rails应用程序，我也在运行Rails 3.2.14并且有以下内容：

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

在将此资产块添加到gemfile之前，请先使用第二种方法。删除您的Gemfile.lock，然后将资产块添加到Gemfile，保存并运行bundle update

无法构建不同版本的gem原生扩展ruby racer gem
