我正在尝试在Bloomberg和Python之间建立数据管道。我有一个Bloomberg终端，一个Windows 64位计算机，Python 3.7.4和一个Sublime Text环境，并且可以正常工作。我的目标是安装XBBG软件包：https://pypi.org/project/xbbg/。
我已经按照https://pypi.org/project/xbbg/上的步骤进行了安装，
即使我尝试使用pip install pyarrow的早期版本，pyarrow安装也不起作用（请参阅下面的回溯）。
pip install pyarrow

我尝试阅读此问题，在我看来，要么：
我做错了安装。
如果1）我很乐意降级我的python版本。如果您知道哪个python版本（超过3个）支持pyarrow，我将很乐意将其降级。 如果2）请提供有关如何正确安装的指示。
（不太可能）如果有一种无需安装pyarrow即可安装xbbg的方法，我将很高兴知道如何。记住目标是安装xbbg。
非常感谢。
答案 0 :(得分：1)
pyarrow requires 64-bit Python。验证您是否拥有64-bit Python：
python -c "import sys; print(sys.maxsize > 2**32)"
python -c "import struct; print(struct.calcsize('P') * 8)"
