无法在 Vagrant SSH windows 7 32 位中构建 gem 本机扩展 nio4r

Question

我在 Windows 7 32 位主机中使用 Vagrant with the box ubuntu/trusty32 设置 Rails 环境。我坚持 bundle install --path=./vendor/bundle。我收到以下错误：

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

    current directory: /vagrant/vendor/bundle/ruby/2.4.0/gems/nio4r-2.1.0/ext/nio4r
/home/vagrant/.rbenv/versions/2.4.1/bin/ruby -r ./siteconf20170911-24730-8nkvsn.rb extconf.rb

Gem files will remain installed in /vagrant/vendor/bundle/ruby/2.4.0/gems/nio4r-2.1.0 for inspection.
Results logged to /vagrant/vendor/bundle/ruby/2.4.0/extensions/x86-linux/2.4.0-static/nio4r-2.1.0/gem_make.out

An error occurred while installing nio4r (2.1.0), and Bundler cannot continue.
Make sure that `gem install nio4r -v '2.1.0'` succeeds before bundling.

In Gemfile:
  rails_admin was resolved to 1.2.0, which depends on
    rails was resolved to 5.0.6, which depends on
      actioncable was resolved to 5.0.6, which depends on
        nio4r

问题好像是gemnio4r的问题。我试过这些：

• gem install bundler
• bundle update
• gem uninstall nio4r
• gem install nio4r（这样就成功安装了gem）
• rm Gemfile.lock
• bundle install

None以上作品。我也试过这个：

sudo apt-get install ruby2.2-dev

但是找不到包裹。

E: Unable to locate package ruby2.2-dev
E: Couldn't find any package by regex 'ruby2.2-dev'

错误主要指向消息Text file busy @ unlink_internal - ./siteconf20170911-24730-8nkvsn.rb。 I found a solution and I followed the steps described in the article.

通过将包路径更改为 VM 本地目录（不在共享文件夹中），错误消失了。

1. 新建目录

   mkdir ~/.bundles
   

2. 将此添加到 /vagrant/.bundle/config

   BUNDLE_PATH: "/home/vagrant/.bundles/PROJECT_NAME_HERE"
   BUNDLE_DISABLE_SHARED_GEMS: "1"
   

3. 运行 bundle install
