即使已安装且位于python/sitepackages文件夹中，也找不到folium版本

Question

这是我的map.py代码：

import folium

map = folium.Map(location=[42.3601, -71.0589], zoom_start=12)
map.save('map.html')

这就是错误：

File "map.py", line 2, in <module>
    import folium   File "/Users/tomerrajuan/Library/Python/2.7/lib/python/site-packages/folium/__init__.py",
line 8, in <module>
    import branca   File "/Users/tomerrajuan/Library/Python/2.7/lib/python/site-packages/branca/__init__.py",
line 1, in <module>
    import branca.colormap as colormap   File "/Users/tomerrajuan/Library/Python/2.7/lib/python/site-packages/branca/colormap.py",
line 15, in <module>
    from branca.element import ENV, Figure, JavascriptLink, MacroElement   File
"/Users/tomerrajuan/Library/Python/2.7/lib/python/site-packages/branca/element.py",
line 13, in <module>
    from urllib.request import urlopen ImportError: No module named request

Answer 1

您必须手动安装requests包

这可以通过在终端/cmd中运行以下命令来完成：

pip install requests
