我正在使用 Visual Studio 代码尝试从 Binance 中提取蜡烛，但我不断收到以下错误：
ModuleNotFoundError: No module named 'binance.client'; 'binance' is not a package
这是导致错误的代码行：
from binance.client import Client
我确保我 pip 将 python-binance 安装到了正确版本的 python 并且从我读到的内容中我猜测路径有问题，但我不确定要查找什么。我运行以下代码检查路径
import pprint, os
import binance
pprint.pprint(os.path.abspath(binance.__file__))
这是我的结果
'/Users/myName/.local/lib/python3.7/site-packages/binance.py'
我读到拥有名为 binance.py 的文件可能会弄乱它，但这是下载时给出的名称。如果您对这里的外观感到好奇，那就是：
