DateUtil.Parser错误：无法导入名称“ isoparse”

Question

我正在尝试执行以下代码，但出现错误“ ImportError：无法导入名称'isoparse'”。我尝试安装python-dateutil，但错误仍然存​​在。

代码来自https://github.com/yannforget/pylandsat

from datetime import datetime

import pandas as pd
from shapely.geometry import Point
from pylandsat import Catalog, Product

catalog = Catalog()

begin = datetime(2000, 1, 1)
end = datetime(2010, 1, 1)
geom = Point(4.34, 50.85)

# Results are returned as a pandas dataframe
scenes = catalog.search(
    begin=begin,
    end=end,
    geom=geom,
    sensors=['ETM', 'LC08']
)

# Get the product ID of the scene with the lowest cloud cover
scenes = scenes.sort_values(by='cloud_cover', ascending=True)
product_id = scenes.index[0]

# Download the scene
product = Product(product_id)
product.download(out_dir='data')

错误是：
