我也做了
sudo bundle install
再次出错： “安装eventmachine（0.12.10）时发生错误，Bundler无法继续。确保gem install eventmachine -v'0.12.10'在捆绑之前成功。”
现在我做的时候
sudo gem install eventmachine -v '0.12.10'
我再次收到错误消息：
"ERROR: Error installing eventmachine: ERROR: Failed to build gem native extension."
请告诉我我错过了什么。
答案 0 :(得分：6)
要在Ubuntu 14.04上安装 eventmachine 1.0.3 ，首先需要运行：
sudo apt-get install build-essential
然后bundle install或gem install eventmachine
应该足够了。
注意：如果您有rbenv，请务必在rbenv rehash之后运行bundle install。

尝试安装openssl和libstdc ++ 如果你使用rvm并在单用户模式下安装了ruby，你应该省略sudo。
您可以粘贴错误的完整日志吗？用这个更容易回答你的问题。

尝试更新您的系统RubyGems。
我希望这适合你。
答案 4 :(得分：0)
对于无法使用上述方法解决的其他人：
sudo -u gitlab -H bundle config build.eventmachine --with-cflags=\"-O2 -pipe -march=native -w\"
sudo -u gitlab -H bundle config build.thin --with-cflags=\"-O2 -pipe -march=native -w\"
正如用户enrico here所述。

试试gem install eventmachine -- --with-openssl-dir=/usr/local/opt/openssl@1.1
