uniswap-python“无法从部分初始化的模块'Uniswap‘导入名称'uniswap’(很可能是由于循环导入)”

Question

我正在尝试熟悉uniswap-python模块，但在第一次测试时就已经被卡住了。这段代码来自getting started guide

from uniswap import Uniswap

address = None          # or None if you're not going to make transactions
private_key = None  # or None if you're not going to make transactions
version = 2                       # specify which version of Uniswap to use
provider = "https://mainnet.infura.io/v3/c4bcdc3744df4340b875e095b0713258"    # can also be set through the environment variable `PROVIDER`
uniswap = Uniswap(address=address, private_key=private_key, version=version, provider=provider)

# Some token addresses we'll be using later in this guide
eth = "0x0000000000000000000000000000000000000000"
bat = "0x0D8775F648430679A709E98d2b0Cb6250d2887EF"
dai = "0x6B175474E89094C44Da98b954EedeAC495271d0F"

uniswap.get_price_input(eth, dai, 10**18)

我得到了这个错误：

Traceback (most recent call last):
  File "c:\Users\phil\Desktop\Python\uniswap.py", line 1, in <module>
    from uniswap import Uniswap
  File "c:\Users\phil\Desktop\Python\uniswap.py", line 1, in <module>
    from uniswap import Uniswap
ImportError: cannot import name 'Uniswap' from partially initialized module 'uniswap' (most likely due to a circular import) (c:\Users\phil\Desktop\Python\uniswap.py)

Answer 1

您的文件名为uniswap.py

c:\Users\phil\Desktop\Python\uniswap.py

现在，from uniswap import ...加载您的文件，而不是模块uniswap。

只需重命名您的文件-即。test-uniswap.py。

c:\Users\phil\Desktop\Python\test-uniswap.py
