将Gitlab从9.3.7更新到9.3.8,安装re2时出错

我们使用Gitlab 9.3.7在Ubuntu 14.04上运行,工作正常.我们正在尝试更新到Gitlab v9.3.8的最新安全补丁,但它给了我们这个错误:

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

我尝试使用Ruby 2.3添加ruby-dev和ruby2.3-dev.更新没有变化.由于这是一个相当新的补丁,Gitlab在他们的网站上没有进一步的信息,并且re2的安装说明没有帮助.

安装lib后我能够安装re2-gem:

apt-get install libre2-dev

我有同样的问题
它适合我,尝试你自己的风险

Ubuntu 14.04没有libre2-dev
https://launchpad.net/ubuntu/+source/re2

我是从https://github.com/google/re2/wiki/Install来源安装的

cd /tmp git clone https://github.com/google/re2.git cd re2/ make make test sudo checkinstall -D --install=no sudo dpkg -i re2_20170720-1_amd64.deb

然后运行
ldconfig
