Answer 1

我有完全相同的问题。我正在运行Windows 7 64位，并在可移植Python 3.7.3上运行。

当Jupyter失败时，我正在以下路径上运行Portable Python：

E:\applications\python37\Portable Python-3.7.3\App\Python

卸载并重新安装Jupyter，输入模块不能解决问题。

我怀疑路径名有问题，因此我将python安装复制到没有空格的路径（也许是更短的路径？）：

E:\applications\python37\Python

最后，我设法让Jupyter Notebook工作！

Answer 2

我遇到了同样的问题，这就是我的解决方法

Python 3.5.1没有类型。

https://github.com/django-extensions/django-extensions/issues/1188

C:\Users\rigupta>D:\Anaconda3\python
Python 3.5.1 |Anaconda 4.0.0 (64-bit)| (default, Feb 16 2016, 09:49:46) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import typing
>>> typing.Type
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'typing' has no attribute 'Type'
>>> typing.type
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'typing' has no attribute 'type'
>>>

所以我通过运行下面的命令将python版本升级到3.5.4，

conda update --all
