Question

我是python的新手，并尝试通过使用以下命令为Jupyter的内核添加python 3

python3 -m pip install ipykernel

但是得到了

Exception:
Traceback (most recent call last):
  File "/usr/share/python-wheels/setuptools-3.3-py2.py3-none-any.whl/pkg_resources.py", line 2482, in _dep_map
    return self.__dep_map
  File "/usr/share/python-wheels/setuptools-3.3-py2.py3-none-any.whl/pkg_resources.py", line 2344, in __getattr__
    raise AttributeError(attr)
AttributeError: _DistInfoDistribution__dep_map

During handling of the above exception, another exception occurred:

ValueError: ("Expected ',' or end-of-list in", 'pytest ==3.2.*', 'at', '*')

我有python2和python3但命令

 python --version

给我

 Python 3.4.3

和命令

 jupyter kernelspec list

给我

 Available kernels:
  python2    /usr/local/share/jupyter/kernels/python2

Answer 1

我通过此命令解决了

sudo apt-get remove ipython3
ipython3-notebook
sudo apt-get install pip3
sudo pip3 install ipython
sudo ipython kernelspec install-self
sudo ipython3 kernelspec install-self

通过@ Teque5
