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...

e chosen to use the version of V8 found on your system (Libv8::Location::System::NotFoundError)
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

我想知道这个错误消息的真正含义是什么？
我也查了这个https://github.com/cowboyd/libv8#bring-your-own-v8 https://github.com/cowboyd/libv8#bring-your-own-v8如何安装 v8 的标头？
当我遇到这个问题时，我发现我在开发中不需要这些gem，因为rails用于预编译你的资产，所以我的解决方案非常简单，
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
