以前装了 jupyter notebook ,可以用的(pip install jupyter),但是没过一阵子就发现用不了了,泪崩,还没当回事,但上周数据挖掘作业一定要用到jupyter notebook,搞了好几天都没发现问题所在,今天早上看了一篇博客终于知道怎么回事了
https://blog.csdn.net/candcplusplus/article/details/72793591
首先我在控制台(cmd)打开 jupyter notebook是这样的
C:\Users\17119>jupyter notebook
Traceback (most recent call last):
File "c:\users\17119\appdata\local\programs\python\python36-32\lib\runpy.py", line 193, in _run_module_as_main

from markupsafe._compat import text_type, string_types, int_types, \
ModuleNotFoundError: No module named 'markupsafe._compat'
注意,打开notebook后不是我这样的用不来我下面的解决办法,请自行找其他方法吧~
注意到最后一句话:No module named 'markupsafe._compat' ——我擦,居然说这个包里面找不到_compat.py文件,我当时就很纳闷,难道我pip 装的包会有缺失?那不是扯淡吗。
然后就问度娘, 他娘累,真有跟我一样的,赶紧找到 这个markupmarkupsafe 文件夹——File "c:\users\17119\appdata\local\programs\python\python36-32\lib\site-packages\markupsafe\__init__.py", line 14, in
是这样的:
当时就我擦嘞,果然没有 那个_cmpat.py文件,赶紧加进去,内容:
# -*- coding: utf-8 -*-
"""
markupsafe._compat
~~~~~~~~~~~~~~~~~~
Compatibility module for different Python versions.

"""
import sys
PY2 = sys.version_info[0] == 2
if not PY2:
text_type = str
string_types = (str,)
unichr = chr
int_types = (int,)
iteritems = lambda x: iter(x.items())
else:
text_type = unicode
string_types = (str, unicode)
unichr = unichr
int_types = (int, long)
iteritems = lambda x: x.iteritems()
保存,如下:
然后 抱着试一试的心态,运行jupyter notebook
成功!amazing!
