为什么我在使用 python binance 库时会出现此错误？

Question

当我运行我的代码时，我得到了这个错误。如果我搜索此错误，我只会得到文件名为 binance.py 的结果，这会给出错误，但我将文件命名为 bin_bot.py

错误：

Traceback (most recent call last):
  File "bin_bot.py", line 3, in <module>
    from binance.client import Client
ModuleNotFoundError: No module named 'binance'

我的代码：

import os

from binance.client import Client

api_key = os.environ.get("My API")
api_secret = os.environ.get("My Secret")

client = Client(api_key, api_secret)

print(client.futures_account_balance())

感谢您的任何回答。

错误2：

  File "bin_bot.py", line 10, in <module>
    print(client.futures_account_balance())
  File "/usr/local/lib/python3.8/dist-packages/binance/client.py", line 5361, in futures_account_balance

Answer 1

我认为您的系统上同时具有 python2 和 python3。

PIP 已经为 python2 安装了python-binance，并且脚本使用 python3 运行 试试：

python3 -m pip install python-binance

Answer 2

试试

pip install python-binance

然后当我在 binance 之后删除 .client 时我很幸运。

import os

from binance import Client

api_key = os.environ.get("My API")
api_secret = os.environ.get("My Secret")

client = Client(api_key, api_secret)

print(client.futures_account_balance())

文档 https://python-binance.readthedocs.io/en/latest/

在文档中，他们只是调用 bianance，而不是 binance.client。
