bazel：检测到工作区文件中的循环。这表明在定义之前使用了存储库

Question

我有以下文件并尝试使用 bazel 6.1.1 编译简单的 python 应用程序并出现错误。

我的档案：

➜ tree                              
.
├── BUILD
├── main.py
└── WORKSPACE

错误：

➜ bazel build //...
WARNING: Ignoring JAVA_HOME, because it must point to a JDK, not a JRE.
ERROR: Failed to load Starlark extension '@io_bazel_rules_docker//repositories:repositories.bzl'.
Cycle in the workspace file detected. This indicates that a repository is used prior to being defined.
The following chain of repository dependencies lead to the missing definition.
 - @io_bazel_rules_docker
This could either mean you have to add the '@io_bazel_rules_docker' repository with a statement like `http_archive` in your WORKSPACE file (note that transitive dependencies are not added automatically), or move an existing definition earlier in your WORKSPACE file.
