基准安装错误，ModuleNotFoundError: No module named 'main'

Question

为什么会出现这个错误？我不能再安装基准了。我需要导入包含在基准测试中的“get_data”。怎么了？

pip 安装基准

Answer 1

benchmark 与 python 版本 >= 3 不兼容。

你需要 python 2。

在使用 python 3 的虚拟环境中

~/workspace/so via ? v3.8.5 via C python3 
❯ pip install benchmark

使用 python 2：

~/workspace/so via ? v2.7.18 :: Anaconda, Inc. via C python2 
❯ pip install benchmark           
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support
