Lightkurve 模块导致“导入错误：无法导入名称解析”？

编程问答 2022-05-02

问题描述

我正在尝试运行 Python 模块 Lightkurve，目前在 Python 3.8.2 中。我写的代码，来自他们的 quickstart 是：

import lightkurve as lk

from lightkurve import search_targetpixelfile
pixelfile = search_targetpixelfile("KIC 8462852",quarter=16).download();

但是，我一直遇到ImportError：无法导入名称解析异常：

---------------------------------------------------------------------------

     14 import astropy.coordinates as coord
     15 

ImportError: cannot import name parse

我认为这是从 Python 2 过渡到 3 的问题（我通常使用 2；我只使用 3，因为这是 Lightkurve 使用的！），鉴于错误，但我在弄清楚要做什么时遇到了一些麻烦做。谁能给我一些建议？
