在我的 Node.js 项目文件夹中运行bx dev build时遇到错误，特别是：
[hafiz@Ubuntu ~/FSFTM/code/TaskListApp] $ sudo bx dev build

Dumping output from the command:

就在这些之前，我跑bx login --ssobx target --cf.无法确切地说出问题是什么，我怀疑这与 Docker 有关。我在 Ubuntu 16.04 上运行它。通过运行curl -sL https://ibm.biz/idt-installer | bash安装 idt 。这是 bx 的版本：
[hafiz@Ubuntu ~/FSFTM/code/TaskListApp] $ bx -v
bx version 0.6.4+41cb1aa-2017-12-19T03:46:07+00:00
不太确定我还应该包括什么，我有点难倒了。该项目通过运行npm install、npm run build和npm run start来构建良好。如果我知道什么是有用的，我会提供额外的信息！任何知道错误真正含义的人，或者我是否错过了什么？
根据乔的要求，以下是痕迹：

从做一些研究来看，在开源container_linux.go中报告问题的第 295 行似乎与用户文件权限有关。 从您的描述来看，您的系统可能有一些root拥有的文件，当您使用自己的用户帐户运行命令时，这些文件现在无法访问(如您提供的日志所示)。 我怀疑一些chown会让你建造得很好。
仅供参考
仅供参考，服务凭据故障对构建无害。
我看到你上一次build你没有使用sudo，这很好。 为了进一步调试它，您是否尝试过为另一种语言构建项目？ 例如Java还是Swift？ 到目前为止，我无法重现失败。
谢谢
您尝试使用sudo运行bx dev build的原因是什么？ 你也跑bx dev createsudo吗？ 这听起来像是一个权限问题。
错误消息实际上来自 Docker，而不是 IBM Developer Tools 可执行文件的内部：
OCI runtime exec failed: exec failed: container_linux.go:295: starting container process caused "process_linux.go:86: executing setns process caused "exit status 22"": unknown
