python-2.7 - Apache Beam - pip install '.[gcp,test]' - RuntimeError: Not in apache git tree; 找不到原型定义

Question

我正在尝试遵循使用 Python SDK 开发的 Apache Beam 贡献指南

使用 Python 2.7.15 步骤：

1. git clone [e-mail]:apache/beam.git
2. 创建一个新的虚拟环境 (--no-side-packages )
3. 点安装cython
4. pip install '.[gcp,test]' 在这个 sdks/python 目录上运行

输出：

pip install '.[gcp,test]'

第 68 行中的文件“gen_protos.py”：

if not os.path.exists(common):
        raise RuntimeError(
            'Not in apache git tree; unable to find proto definitions.')

它失败了，因为这条路径不存在：

当时常见的是：

/private/var/folders/k9/6y5rqvq91fv360rq0p271mkr0000gn/T/pip-req-build-YZpmvt/../common

我对光束很陌生，我错过了什么吗？

由于您是从源代码安装 Apache Beam，因此您需要使用-e传入的标志进行安装，以便以“可编辑”模式安装。：

pip install -e .[gcp,test]
