Coveralls不在使用Docker的Django应用上提交

Question

我正在使用Docker开发Django项目。我已经配置了Travis-Ci，并且想要将测试范围提交给所有人员。但是，它没有按预期工作。任何帮助将不胜感激。

这是我得到的错误

要了解为什么不提交承保范围，您必须了解Docker容器的工作方式。

创建该容器是为了模仿一个单独的独立单元。这意味着在全局上下文中运行的命令与在容器上下文中运行的命令不同。

在您的情况下，您正在运行测试并在容器的上下文中生成一个覆盖率报告，然后尝试向全局上下文中的所有人员提交报告。

由于文件位于容器中，coveralls命令无法找到该报告，因此不会提交任何内容。
