我已经在系统中安装了 ipython notebook,但是当我想在终端中运行它时,出现以下错误:
File "/usr/local/lib/python2.7/dist-packages/ipython-3.2.0-py2.7.egg/IPython/html/notebookapp.py", line 52, in <module>
from tornado import httpserver

from tornado.netutil import ssl_wrap_socket, ssl_match_hostname, SSLCertificateError, _client_ssl_defaults, _server_ssl_defaults
File "/usr/local/lib/python2.7/dist-packages/tornado/netutil.py", line 39, in <module>
import certifi
ImportError: No module named certifi
有人知道问题出在哪里吗?任何建议都将不胜感激。
答案1
看起来您缺少 IPython Notebook 的依赖项。如果您尚未安装pip
,我建议您安装它,以便于安装 python 包:
sudo apt-get install python-pip python-dev build-essential
安装 pip 后,您可以在命令行中输入以下命令来安装 IPython Notebook 及其所有依赖项:
pip install "ipython[notebook]"
sudo
如果出现错误,您可能也必须运行该错误。
