重建错误：无子进程 (Errno::ECHILD)，来自 /pups/lib/pups/exec_command.rb:88:in `block in spawn'

支持 安装

你好。我想安装一个插件（data explorer），所以在我的 app.yml 中添加了 git 行。
重建失败了：

我原以为是插件的问题，所以从 app.yml 中移除了它并重新构建，但错误依旧。
目前我的 Discourse 可以正常运行，但我无法重新构建，这可能会导致未来的问题，因此我需要解决它。

有什么修复建议吗？

This is a known issue in our new image cc @falco @sam there is an error being reported as part of the rebuild, every time.

I see what this is:

Will sort out pups to allow for this.

Okay so nothing to do on my side, just waiting for an update I guess :slight_smile:

Oh the particular error you are seeing in the logs (which I just fixed) is unrelated.

bundle exec rake assets:precompile is failing for you which is usually due to plugins. I would try rebuilding again and triple check there are no plugins involved.

Yes it was because of a plugin. Weird, it didn’t cause this issue before.
