python - travic ci 错误 AttributeError : 'module' object has no attribute 'hashpw'

Question

我正在使用 travis ci 和单元测试。测试在本地工作，但在 travis ci 中不知何故失败这是日志的一部分。

======================================================================

ERROR: test_environment_is_development (test_config.TestConfigurations)

AttributeError: 'module' object has no attribute 'hashpw'

特拉维斯也一直告诉我我的测试已经通过，尽管事实并非如此

更新

我在本地做了一些测试，我用 pip 删除了 py-bcrypt 模块并运行测试，我在 travis 上遇到了同样的错误，当我重新安装它时一切正常。(它在 travis ci 上仍然损坏)

Answer 1

我解决了我的问题，问题是 travis ci 使用的是过时版本的 pip解决方案只需将其添加到 .travis.yml

install: "pip install --upgrade pip && pip install -r requirements.txt"
