我正在运行Python 3.5.1 for Mac.我想用urllib2.我尝试安装它,但我被告知它已被拆分为urllib.request和urllib.error for Python 3.
我的命令(暂时从框架bin目录运行,因为它不在我的路径中):
sudo ./pip3 install urllib.request
返回:
Could not find a version that satisfies the requirement urllib.request (from versions: )
No matching distribution found for urllib.request
我在尝试一举安装urllib2之前遇到了同样的错误.
我尝试使用Basemap包来绘制PyCharm的地图,但是我遇到了问题
from mpl_toolkits.basemap import Basemap`
跟踪追溯如下:
Traceback (most recent call last):
File "/Users/yupeipei/anaconda3/lib/python3.6/site-packages/IPython/core/interactiveshell.py", line 2963, in run_code

File "<ipython-input-4-0a24a3a77efd>", line 7, in <module>
from mpl_toolkits.basemap import Basemap

pyproj_datadir = os.environ['PROJ_LIB']
File "/Users/yupeipei/anaconda3/lib/python3.6/os.py", line 669, in __ getitem__
raise KeyError(key) from None
KeyError: 'PROJ_LIB'
我对PyCharm上的这个错误感到困惑,因为相同的脚本在Jupyter或Spyder上运行正常!PyCharm的环境是../anaconda3/lib/python3.6,其中与anaconda相同.
有没有人遇到过这个错误？
任何人都可以帮我解决这个错误吗？
