bundle install/update:libv8(therubyracer)安装失败(带有本机扩展)

Question

我最近想更新我的gem包但遇到了libv8的安装问题(对therubyracer的要求):

Installing libv8 (3.3.10.3) with native extensions /usr/local/rvm/rubies/ruby-1.9.3-head/lib/ruby/site_ruby/1.9.1/rubygems/installer.rb:552:in `rescue in block in build_extensions': ERROR: Failed
 to build gem native extension. (Gem::Installer::ExtensionBuildError)

        /usr/local/rvm/rubies/ruby-1.9.3-head/bin/ruby extconf.rb 
Checking for Python...*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

我在therubyracer github网站上找到了问题报告,它建议卸载并重新安装libv8,但这不适用于我的Ubuntu 11.04机器.任何想法 - 还是我坚持旧版本一段时间？

Answer 1

尝试一下这一次:

gem 'therubyracer'
gem 'libv8', '3.16.14.3'

应该有所帮助

使用新的捆绑包也更好: gem install bundler --pre

Answer 2

我的老Ubuntu 10.04(x64)上有类似的问题

在我更新项目之后,Gemfile拥有了这些宝石

  gem 'libv8', '~> 3.11.8'
  gem "therubyracer", '>= 0.11.0beta1', :require => 'v8'

但当我运行'捆绑安装'时,我收到了一个错误

Installing therubyracer (0.11.0beta1) with native extensions 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

这是一个有助于我快速解决该障碍的步骤列表

1. 卸载所有版本的宝石'libv8'和'therubyracer'

   >宝石卸载therubyracer

   > gem uninstall libv8

2. 手动安装therubyracer

   >宝石安装therubyracer

   获取:libv8-3.3.10.4-x86_64-linux.gem(100%)获取:therubyracer-0.10.1.gem(100%)构建本机扩展.这可能需要一段时间...已成功安装libv8-3.3.10.4-x86_64-linux已成功安装therubyracer-0.10.1已安装2个宝石安装libv8-3.3.10.4-x86_64-linux的ri文档...为therubyracer安装ri文档-0.10.1 ...为libv8-3.3.10.4-x86_64-linux安装RDoc文档...为therubyracer-0.10.1安装RDoc文档...

3. 检查已安装宝石的版本

   >宝石清单| grep libv

   libv8(3.3.10.4 x86_64-linux)

   >宝石清单| grep therubyracer

   therubyracer(0.10.1)

4. 在Gemfile中设置这些版本并运行

   >捆绑安装

5. 摘要.我明白,在我的情况下,我没有使用最新的版本,它可能是兼容性的坏.但至少我可以继续发展.

Answer 3

Ubuntu 11.04

gem "therubyracer", '0.11.1'
gem 'libv8'

1. 卸载therubyracer和libv8 gem

2. 更新bundler gem版本

3. 安装lib8-dev包

   sudo apt-get install libv8-dev

4. 然后运行它

   sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion imagemagick graphicsmagick libmagickcore-dev libmagickwand-dev

5. 现在手动安装therubyracer

   宝石安装therubyracer

6. 它将为您安装therubyracer和libv8.

7. 现在运行bundle install

以上所有步骤解决了我的问题:)
