当我将我的Python版本从3.4更新到3.5(在Mac El Capitan上)时,我重新安装了Jupyter但是当我运行它并创建一个新的Python 3笔记本时,它会立即告诉我存在内核错误,如果我点击这个,然后我收到此错误消息:
Traceback (most recent call last): File "/usr/local/lib/python3.5/site-packages/notebook/base/handlers.py", line 436, in wrapper result = yield gen.maybe_future(method(self, *args, **kwargs)) File "/usr/local/lib/python3.5/site-packages/notebook/services/sessions/handlers.py", line 56, in post model = sm.create_session(path=path, kernel_name=kernel_name) File "/usr/local/lib/python3.5/site-packages/notebook/services/sessions/sessionmanager.py", line 66, in create_session kernel_name=kernel_name) File "/usr/local/lib/python3.5/site-packages/notebook/services/kernels/kernelmanager.py", line 84, in start_kernel **kwargs) File "/usr/local/lib/python3.5/site-packages/jupyter_client/multikernelmanager.py", line 109, in start_kernel km.start_kernel(**kwargs) File "/usr/local/lib/python3.5/site-packages/jupyter_client/manager.py", line 244, in start_kernel **kw) File "/usr/local/lib/python3.5/site-packages/jupyter_client/manager.py", line 190, in _launch_kernel return launch_kernel(kernel_cmd, **kw) File "/usr/local/lib/python3.5/site-packages/jupyter_client/launcher.py", line 123, in launch_kernel proc = Popen(cmd, **kwargs) File "/usr/local/Cellar/python3/3.5.0/Frameworks/Python.framework/Versions/3.5/lib/python3.5/subprocess.py", line 950, in __init__ restore_signals, start_new_session) File "/usr/local/Cellar/python3/3.5.0/Frameworks/Python.framework/Versions/3.5/lib/python3.5/subprocess.py", line 1540, in _execute_child raise child_exception_type(errno_num, err_msg) FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/opt/python3/bin/python3.4'
我知道从3.4升级到3.5意味着软件包将安装在不同的地方,但是当我已经再次运行pip3 install jupyter时,我无法弄清楚它在Python 3.5软件包中的用途(并且已经卸载/重新安装)几次).有谁知道修复此问题?
IPython有一个剩余的kernelspec指向你的Python 3.4.您可以看到现有的kernelspecs:
jupyter kernelspec list
您可以使用安装新的IPython kernelspec
ipython kernelspec install [--user]
