can't install scipy - freezes on "Running setup.py install for scipy"
提问by Tom83B
when I run
当我跑
sudo pip install -U scipy
it is first downloaded and then it goes on to show
它首先被下载，然后它继续显示
Running setup.py install for scipy
but it freezes there. I tried upgrading pip itself. Worked fine. My pip version is 1.5.4
但它在那里冻结。我尝试升级 pip 本身。工作得很好。我的 pip 版本是 1.5.4
The only error i get is InsecurePlatforWarning. The complete output looks like this:
