导入matplotlib.pyplot时出错（在Windows 10 Home 64位PC的Anaconda3上）

我最近在Windows 10 Home（64位）机器上安装了“Anaconda3 for Windows v2.4.0”。

（我从https://www.continuum.io/downloads下载了Windows 64位graphics安装程序“Anaconda3-2.4.0-Windows-x86_64.exe”（392 MB）。）

在一个命令提示符窗口中，我做了conda“testing驱动”，包括“conda update conda”等。最后，我看到以下内容：

C:\Users\Anshul\Downloads\Python>conda update conda Fetching package metadata: .... # All requested packages already installed. # packages in environment at C:\Anaconda3: # conda 3.18.6 py35_0 defaults C:\Users\Anshul\Downloads\Python>conda list matplotlib # packages in environment at C:\Anaconda3: # matplotlib 1.5.0 np110py35_0 defaults 

安装似乎已经成功 – 例如：

 C:\Users\Anshul\Downloads\Python>python Python 3.5.0 |Anaconda 2.4.0 (64-bit)| (default, Nov 7 2015, 13:15:24) [MSC v.1900 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> print("Hello World") Hello World >>> import os >>> os.getcwd() 'C:\\Users\\Anshul\\Downloads\\Python' >>> import matplotlib as mpl >>> print(mpl.__version__) 1.5.0 >>> 

请注意，matplotlib导入罚款以上。 但是，当我尝试导入“matplotlib.pyplot”时出现错误消息，如下所示：

 >>> import matplotlib.pyplot as pp Traceback (most recent call last): File "C:\Anaconda3\lib\site-packages\matplotlib\font_manager.py", line 1412, in <module> fontManager = pickle_load(_fmcache) File "C:\Anaconda3\lib\site-packages\matplotlib\font_manager.py", line 963, in pickle_load with open(filename, 'rb') as fh: FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\Anshul\\.matplotlib\\fontList.py3k.cache' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Anaconda3\lib\site-packages\matplotlib\pyplot.py", line 29, in <module> import matplotlib.colorbar File "C:\Anaconda3\lib\site-packages\matplotlib\colorbar.py", line 34, in <module> import matplotlib.collections as collections File "C:\Anaconda3\lib\site-packages\matplotlib\collections.py", line 27, in <module> import matplotlib.backend_bases as backend_bases File "C:\Anaconda3\lib\site-packages\matplotlib\backend_bases.py", line 62, in <module> import matplotlib.textpath as textpath File "C:\Anaconda3\lib\site-packages\matplotlib\textpath.py", line 15, in <module> import matplotlib.font_manager as font_manager File "C:\Anaconda3\lib\site-packages\matplotlib\font_manager.py", line 1420, in <module> _rebuild() File "C:\Anaconda3\lib\site-packages\matplotlib\font_manager.py", line 1405, in _rebuild fontManager = FontManager() File "C:\Anaconda3\lib\site-packages\matplotlib\font_manager.py", line 1043, in __init__ self.ttffiles = findSystemFonts(paths) + findSystemFonts() File "C:\Anaconda3\lib\site-packages\matplotlib\font_manager.py", line 312, in findSystemFonts for f in win32InstalledFonts(fontdir): File "C:\Anaconda3\lib\site-packages\matplotlib\font_manager.py", line 231, in win32InstalledFonts direc = os.path.abspath(direc).lower() File "C:\Anaconda3\lib\ntpath.py", line 535, in abspath path = _getfullpathname(path) ValueError: _getfullpathname: embedded null character >>> 

我在文本编辑器中打开“C：\ Anaconda3 \ lib \ site-packages \ matplotlib \ font_manager.py”，并试图寻找错误的来源。 我认为这是事情出错的地方：

 >>> mpl.get_cachedir() 'C:\\Users\\Anshul\\.matplotlib' >>> mpl.get_configdir() 'C:\\Users\\Anshul\\.matplotlib' >>> 

在Windows资源pipe理器中，我看到“C：\ Users \ Anshul.matplotlib”文件夹是空的，因此“fontList.py3k.cache”文件的FileNotFoundError （我在“C：\ Anaconda3” “目录）。 这似乎是安装程序的问题（我认为），但我不知道如何解决它。 我会很感激任何帮助或指针。

（顺便说一句，我已经试过用googlesearch这个问题了，最近的那个是在2013年的时候报告过的： 无法导入matplotlib.pyplot＃2320 ，它涉及WinPython-64bit-3.3.2.2在Windows 7 64位这个线程被closures了，注释：“closures，已经被修复了”，但是问题已经出现了，希望有一个简单的解决方法或者解决方法。

谢谢，
