Question

我终于在我的Windows上安装了libv8 gem install libv8 - --with-system-v8

现在，当我尝试安装therubyracer时，我得到了

gem install therubyracer
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...

and *not* the one that is bundle with the libv8 rubygem. However,
it could not be located. please make sure you have a version of
v8 that is compatible with 3.16.14.3 installed. You may
need to special --with-v8-dir options if it is in a non-standard
location

我想知道的是这个错误信息的真正含义是什么？我也查了一下https://github.com/cowboyd/libv8#bring-your-own-v8 如何为v8安装标头？

Answer 1

当我遇到这个问题时，我发现我在开发中不需要那些宝石，因为rails用来预编译你的资产，所以我的解决方案非常简单，

的Gemfile

gem "rails"

group :production do
  gem 'therubyracer'
end

然后当你捆绑运行这个命令

$ bundle install --without production

然后对生活微笑：D

Answer 2

在Mac上，您可以尝试使用自制程序更新v8库：

gem uninstall libv8
brew install v8
gem install therubyracer

更新：抱歉，没有意识到这只是一个Windows问题。

Answer 3

@Aalap

我在Windows 7 64位上设置Ruby on Rails Web应用程序时遇到了同样的问题。我遇到了这个solution。这有点旧但解决了这个问题。此解决方案提供'therubyracer'gem文件和v8.dll libs进行安装。上面的链接中的说明非常清楚。

我安装'libv8'gem就像Periback's answer on SO一样，当我尝试安装'therubyracer'gem时，它失败并出现与你相同的错误。现在我的Web应用程序运行正常，我的“gem list”命令显示：

libv8（3.11.8.13）

therubyracer（0.11.0beta1 x86-mingw32）

希望这有帮助。

在安装了libv8的windows上安装therubyracer --with-system-v8
