ruby – 无法安装bson_ext 1.8.2 gem

我无法在我的mongo项目目录中安装bson_ext 1.8.2 gem.
具体我试着运行bundle install和gem install bson_ext -v’1.8.2′

我在论坛上尝试了其他解决方案但是徒劳无功.

An error occurred while installing bson_ext (1.8.2),and Bundler cannot continue.
Make sure that `gem install bson_ext -v '1.8.2'` succeeds before bundling.

gem install bson_ext -v’1.8.2失败并出现相同的错误.

这里的解决方案(https://jira.mongodb.org/browse/RUBY-551?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel)说它固定了……但我仍然面对同样的问题

解决方法

尝试更新rubygems然后安装bson_ext.

gem update --system
gem install bson_ext
