Python 分子抱怨；[703]应更改默认元数据：description"；在运行基本测试时

我无法运行

molecular test

命令，因为它会抛出下面的错误，而我可以运行没有任何错误的单个命令（还提供了下面的调试o/p）

然而，如果我运行下面的命令，它就可以完美地工作。 所以，谁能指出为什么整个测试都失败了，我该怎么办

太长，读不下去了
这些是ansible lint报告的错误/良好做法，您应该修复。只需启动
molecular lint
，即可自行运行
lint
阶段

从当前输出中，您只需要在角色的
meta/main.yml
中添加一些信息

到底发生了什么
每个
molecular
命令（例如
converge
，
create
，
destroy
，
test
…）都会启动一系列有关您角色的步骤（序列）。您可以在命令输出中看到步骤列表，如下例所示，该示例取自您在运行
converge
时提出的问题：

└── default
    ├── dependency
    ├── create
    ├── prepare
    └── converge

默认情况下会配置这些序列，但可以在场景目录中的
molecular.yml
中进行自定义。如果你对这个主题感兴趣，你可以看一看a

默认情况下，
converge
序列不包含
lint
阶段。因此，您可以运行测试剧本，而无需验证所有内容

另一方面，
测试
序列包括以下所有步骤：

└── default
    ├── lint
    ├── dependency
    ├── cleanup
    ├── destroy
    ├── syntax
    ├── create
    ├── prepare
    ├── converge
    ├── idempotence
    ├── side_effect
    ├── verify
    ├── cleanup
    └── destroy

如您所见，第一个是
lint
，它（默认情况下再次）应该在所有yml文件上运行，然后是角色和测试剧本，最后是python文件（测试、自定义模块、自定义插件过滤器…）

您的完整测试失败，因为最佳实践检查器ansible lint正在报告您应该修复的问题。据我所见，它们非常琐碎，应该在
meta/main.yml
