Question

我正在使用Visual Studio代码尝试从平衡器中抽蜡烛，但我不断收到以下错误：

ModuleNotFoundError: No module named 'binance.client'; 'binance' is not a package

以下是导致错误的代码行：

from binance.client import Client

我已经确保我将python-binance安装到正确版本的python上，并且从IVE读取的内容中猜测路径存在问题，但不确定要查找的内容。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'

我读到具有名为binance.py的文件可能会使其混乱，但这是下载该文件时给出的名称。如果您对这里的外观感到好奇，那就是：

感谢任何帮助或建议，谢谢！

Answer 1

我将文件夹的名称从“binance”更改为“binance_mod”，这解决了问题。我相信错误在于 binance 文件夹和 binance.py 文件都在站点包中。

从那里我刚刚做的

from binance_mod.client import Client

我没有问题

Answer 2

卸载，重新安装，升级。

python -m pip卸载python-binance

python -m pip安装python-binance

python -m pip install-升级python-binance

2。看起来您正在编写的binance.py文件位于站点包中。当您安装python-binance时，在您的站点软件包中创建了一个名为binance的文件夹

您可以移动正在处理的文件或重命名正在处理的文件。

这就是你在做什么：

从binance.client导入客户端

这是什么意思：

从位于site_packages的binance文件夹中的

从client.py文件导入客户端类。

由于您具有binance.py，因此它可能会覆盖binance文件夹，但不能确定为什么模块会尝试自行导入。除非您做的不同。

Answer 3

尝试安装binance-connector-python pip3 install binance-connector-python

Answer 4

我通过专门使用 conda 安装twisted 解决了这个问题：（其他来源不起作用）

conda install twisted

为什么收到此错误'ModuleNotFoundError：没有名为'binance.client'的模块；安装币安后，“币安”不是软件包吗？
