奇点错误：无法挂载图像（只读）：参数无效

Question

我尝试从dockerhub上的docker图像构建一个奇点图像。

singularity build pcgr.simg docker://sigven/pcgr:0.5.3

然后当我尝试执行它时：

singularity exec pcgr.simg ls

它给了我这个错误：

ERROR  : Failed to mount image in (read only): Invalid argument
ABORT  : Retval = 255

奇点版本：2.3.1-dist

不知道怎么解决这个问题？

谢谢

附： ：这是构建过程中打印的线条

Answer 1

我仍然试图绕着奇点的方式工作（带着Docker的经验，奇点有点令人困惑）但我发现用sudo运行你的命令会绕过类似的错误。

但仍在阅读其含义是......

Answer 2

默认情况下，singuarity安装/ dev / tmp和$ HOME，但是您正在构建不具有提升权限的不可变图像（simg），这意味着您在安装OS目录时没有root权限，您有几个选项，在/etc/singularity/singularity.conf中修改配置这样您就不会挂载这些目录或使用sudo创建映像。

sudo singularity build pcgr.simg docker: // sigven / pcgr: 0.5.3
