Rubygem 在 launcher 重建应用时超时

支持 安装
1

大家好，

当我尝试通过命令行执行 ./launcher rebuild app 从 2.5.0beta2 升级到 2.5.0.beta3 时，在运行以下命令时不断遇到 RubyGem 超时问题，导致重建失败：

cd /var/www/discourse && gem update bundler

有人遇到过同样的问题吗？有时会在 rubygems.org/specs.4.8.gz 文件上超时，有时则是在特定包上超时。之前在这个实例上的升级都能顺利完成。有什么办法可以解决这个问题吗？如果不行，我准备尝试从备份进行全新安装。

Rubygem 偶尔会出现故障，尤其是在来自或经过中国的 AWS 实例上被大量请求时。

问题是否仍然存在？

是的，我仍然遇到这个问题（在运行于 Compute Canada 的 OpenStack 云基础设施上的实例上）。如果其他人没有遇到类似问题，那更可能是我们本地环境的问题，我会尝试进一步调查..

更新 算了，再试一次后它刚刚完成了！它抱怨超时，但继续使用了锁文件中的解析结果。
