Travis 在使用 pytest 时从 node-sass 中的打印语句中抛出 Python 语法错误

Question

我在使用 pytest-django 测试 Django 应用程序时遇到了 Travis 的 st运行ge 问题。我所有的测试都在本地通过，显然也在 travis 上通过，但无论我做什么，我每次都会收到来自 node-sass 和 node-gyp 的错误。

None 我的测试使用任何节点模块（如果可能的话）。我确实使用具有 gulp-sass 的 gulp，但在测试运行.

之前它是运行时似乎工作正常

这是错误输出：

问题出在 Travis 中已经安装的 pytest 的（旧）版本满足 pytest-django 中的依赖性。将 pytest 的正确版本添加到 requirements.txt 解决了这个问题。
