ruby - 无法安装 therubyracer

Question

我正在尝试在 Debian 6 上执行 gem install therubyracer。我在 1.9.3 上使用 rbenv。当我最初这样做时，它提示 libv8，所以我做了一个 gem install libv8。现在，当我运行 gem install therubyracer 时，出现以下错误，提示找不到该文件。它正在谈论的文件，/home/chop/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/libv8-3.11.8.3-x86_64-linux/vendor/v8/out/然而，x64.release/obj.target/tools/gyp/libv8_base.a 确实存在。

我刚刚遇到了完全相同的错误。我在 https://rubygems.org/gems/therubyracer 查看了 gem 的详细信息看起来我们很“幸运”地在发布当天捆绑了一个新版本。

这似乎已经被报道过:https://github.com/cowboyd/therubyracer/issues/215

所以，我认为最简单的方法是使用最新版本的 gem。所以我更新了我的 Gemfile 以指向最后一个版本，如下所示:

gem "therubyracer", "~> 0.10.2"

我能够成功安装 gem。

如果你想手动安装gem，你可以使用:

gem install therubyracer --version "~> 0.10.2"
