Python 3.x Python错误(ValueError:\u getfullpathname:嵌入的空字符)
我不知道如何修复它请帮忙,我已经尝试了帖子中提到的一切,但没有运气。我是python的新手,正在自学具体细节,非常感谢 控制台:Python 3.x Python错误(ValueError:\u getfullpathname:嵌入的空字符),python-3.x,matplotlib,Python 3.x,Matplotlib,我不知道如何修复它请帮忙,我已经尝试了帖子中提到的一切,但没有运气。我是python的新手,正在自学具体细节,非常感谢 控制台: Traceback (most recent call last): from matplotlib import pyplot File "C:\Users\...\lib\site-packages\matplotlib\pyplot.py", line 29, in <module> import matplotlib.c

我认为您没有正确地应用修补程序:如果应用了,则不应该在错误堆栈中提到
direc=os.path.abspath(direc.lower()
,因为修补程序已将其删除
为了清楚起见,以下是应用修补程序后,matplotlib 2.0.0版本中C:\Anaconda\envs\py35\Lib\site packages\matplotlib\font\u manager.py(或安装了Anaconda的任何位置)中的整个win32InstalledFonts()
方法:
def win32InstalledFonts(directory=None, fontext='ttf'):
"""
Search for fonts in the specified font directory, or use the
system directories if none given. A list of TrueType font
filenames are returned by default, or AFM fonts if *fontext* ==
'afm'.
"""
from six.moves import winreg
if directory is None:
directory = win32FontDirectory()
fontext = get_fontext_synonyms(fontext)
key, items = None, {}
for fontdir in MSFontDirectories:
try:
local = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, fontdir)
except OSError:
continue
if not local:
return list_fonts(directory, fontext)
try:
for j in range(winreg.QueryInfoKey(local)[1]):
try:
''' Patch fixing [Error on import matplotlib.pyplot (on Anaconda3 for Windows 10 Home 64-bit PC)](https://stackoverflow.com/a/34007642/395857)
key, direc, any = winreg.EnumValue( local, j)
if not is_string_like(direc):
continue
if not os.path.dirname(direc):
direc = os.path.join(directory, direc)
direc = os.path.abspath(direc).lower()
'''
key, direc, any = winreg.EnumValue( local, j)
if not is_string_like(direc):

if not os.path.dirname(direc):
direc = os.path.join(directory, direc)
direc = direc.split('\0', 1)[0]
if os.path.splitext(direc)[1][1:] in fontext:
items[direc] = 1
except EnvironmentError:
continue
except WindowsError:
continue
except MemoryError:
continue
return list(six.iterkeys(items))
finally:
winreg.CloseKey(local)
return None
要在font_manager py中找到此选项,请执行以下操作:
direc = os.path.abspath(direc).lower()
将其更改为:
direc = direc.split('\0', 1)[0]
并保存以应用到您的文件中 问题的实际原因似乎在os.path.abspath()
中。更好的解决方案可能是编辑\Lib\ntpath.py
,如中所述
基本上,将ValueError:
异常处理程序添加到abspath()函数的Windows版本中。这在调用堆栈的下方,可以避免您在其他地方遇到此问题。请注意,它适用于Python 2。我在您的帖子中添加了一个完整的回溯,从import matplotlib.pyplot as plt
您已经链接()到了这个问题的解决方案;你对上面提到的修复有完全相同的错误吗?@KeyWeeUsr我删除了赏金。如果你愿意的话,可以在另一篇文章中随意添加。
direc = direc.split('\0', 1)[0]
