调研方向

从 README 的源代码安装说明开始，并检查该设置所引用的开发依赖配置。在 Windows 上使用 Python 3.6 运行 ipykernel 测试套件，并验证缺失的 pytest 和 flaky 导入已得到解决，且没有引入新的测试错误。

由索引模型根据 Issue 内容生成。

描述

After following the instructions in the README - https://github.com/ipython/ipykernel#installation-from-source, running the testsuite on windows + python 3.6 results in import errors because of missing packages. See full output of the test run below.

The packages that are missing from the devenv are - flaky and pytest.
