1、问题描述

 Exception while loading config file C:UsersAdministrator.jupyterjupyter_notebook_config.py     Traceback (most recent call last):       File "C:mysoftwareinstallanacodalibsite-packagestraitletsconfigapplication.py", line 562, in _load_config_files         config = loader.load_config()       File "C:mysoftwareinstallanacodalibsite-packagestraitletsconfigloader.py", line 457, in load_config         self._read_file_as_dict()       File "C:mysoftwareinstallanacodalibsite-packagestraitletsconfigloader.py", line 489, in _read_file_as_dict         py3compat.execfile(conf_filename, namespace)       File "C:mysoftwareinstallanacodalibsite-packagesipython_genutilspy3compat.py", line 198, in execfile         exec(compiler(f.read(), fname, 'exec'), glob, loc)       File "C:UsersAdministrator.jupyterjupyter_notebook_config.py", line 214     SyntaxError: (unicode error) 'utf-8' codec can't decode byte 0xb5 in position 0: invalid start byte 

jupyter_notebook_config中具体配置如下：
c.NotebookApp.notebook_dir = 'D:nanligongmianshiprojectpython第二版'，这里存在中文路径，所以报'utf-8' codec can't decode byte 0xb5 in position 0: invalid start byte的错误。将文件名称去掉或改成中文名称即可。

还有另外一个问题。

[C 23:07:30.387 NotebookApp] Bad config encountered during initialization: [C 23:07:30.387 NotebookApp] No such notebook dir: ''D:\nanligong\mianshi\project\python'' The Jupyter HTML Notebook.  This launches a Tornado based HTML Notebook Server that serves up an HTML5/Javascript Notebook client.  Subcommands -----------  Subcommands are launched as `jupyter-notebook cmd [args]`. For information on using subcommand 'cmd', do: `jupyter-notebook cmd -h`.  list     List currently running notebook servers. stop     Stop currently running notebook server for a given port password     Set a password for the notebook server.  Options -------  Arguments that take values are actually convenience aliases to full Configurables, whose aliases are listed on the help line. For more information on full configurables, see '--help-all'. --debug     set log level to logging.DEBUG (maximize logging output) --generate-config     generate default config file -y     Answer yes to any questions instead of prompting. --no-browser     Don't open the notebook in a browser after startup. --pylab     DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib. --no-mathjax     Disable MathJax          MathJax is the javascript library Jupyter uses to render math/LaTeX. It is     very large, so you may want to disable it if you have a slow internet     connection, or for offline use of the notebook.          When disabled, equations etc. will appear as their untransformed TeX source. --allow-root     Allow the notebook to be run from root user. --script     DEPRECATED, IGNORED --no-script     DEPRECATED, IGNORED --log-level=<Enum> (Application.log_level)     Default: 30     Choices: (0, 10, 20, 30, 40, 50, 'DEBUG', 'INFO', 'WARN', 'ERROR', 'CRITICAL')     Set the log level by value or name. --config=<Unicode> (JupyterApp.config_file)     Default: ''     Full path of a config file. --ip=<Unicode> (NotebookApp.ip)     Default: 'localhost'     The IP address the notebook server will listen on. --port=<Int> (NotebookApp.port)     Default: 8888     The port the notebook server will listen on. --port-retries=<Int> (NotebookApp.port_retries)     Default: 50     The number of additional ports to try if the specified port is not     available. --transport=<CaselessStrEnum> (KernelManager.transport)     Default: 'tcp'     Choices: ['tcp', 'ipc'] --keyfile=<Unicode> (NotebookApp.keyfile)     Default: ''     The full path to a private key file for usage with SSL/TLS. --certfile=<Unicode> (NotebookApp.certfile)     Default: ''     The full path to an SSL/TLS certificate file. --client-ca=<Unicode> (NotebookApp.client_ca)     Default: ''     The full path to a certificate authority certificate for SSL/TLS client     authentication. --notebook-dir=<Unicode> (NotebookApp.notebook_dir)     Default: ''     The directory to use for notebooks and kernels. --browser=<Unicode> (NotebookApp.browser)     Default: ''     Specify what command to use to invoke a web browser when opening the     notebook. If not specified, the default browser will be determined by the     `webbrowser` standard library module, which allows setting of the BROWSER     environment variable to override it. --pylab=<Unicode> (NotebookApp.pylab)     Default: 'disabled'     DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.  To see all available configurables, use `--help-all`  Examples --------      jupyter notebook                       # start the notebook     jupyter notebook --certfile=mycert.pem # use SSL/TLS certificate     jupyter notebook password              # enter a password to protect the server  

还是由于路径错误造成的。c.NotebookApp.notebook_dir = 'D:nanligongmianshiprojectpython'，这里注意需要将D:nanligong改成D:nanligong,其余的一样即D:nanligongmianshiprojectpython，这里有点奇葩，一般win上都是需要加上，但是这里加了反而定位不到。暂时记录一下这个问题吧！还有一个问题。

 NotebookApp] Exception while loading config file C:UsersAdministrator.jupyterjupyter_notebook_config.py     Traceback (most recent call last):       File "C:mysoftwareinstallanacodalibsite-packagestraitletsconfigapplication.py", line 562, in _load_config_files         config = loader.load_config()       File "C:mysoftwareinstallanacodalibsite-packagestraitletsconfigloader.py", line 457, in load_config         self._read_file_as_dict()       File "C:mysoftwareinstallanacodalibsite-packagestraitletsconfigloader.py", line 489, in _read_file_as_dict         py3compat.execfile(conf_filename, namespace)       File "C:mysoftwareinstallanacodalibsite-packagesipython_genutilspy3compat.py", line 198, in execfile         exec(compiler(f.read(), fname, 'exec'), glob, loc)       File "C:UsersAdministrator.jupyterjupyter_notebook_config.py", line 214         c.NotebookApp.notebook_dir = 'D:nanligongmianshiprojectpython'                                                                           ^     SyntaxError: EOL while scanning string literal  

这里已经指的很清楚了。c.NotebookApp.notebook_dir = 'D:nanligongmianshiprojectpython'。末尾不能有。这个路径的细节也太多了，一行配置3个异常，服了。

最终正确的配置应该是c.NotebookApp.notebook_dir = 'D:nanligongmianshiprojectpython',运行启动命令。控制台如下：

根据控制台输出，我们发现程序已经正常启动。

工作目录顺利定位到指定目录。

2、总结

  书上的代码直接运行绝大部分是对的，但是总有一些软件的更新使得作者无能为力。之前的API是对的，但是之后就废弃了或修改了是常有的事。所以我们需要跟踪源代码。这只是一个小小的问题，如果没有前辈的无私奉献，很难想象我们自己一天能学到多少内容。感谢各位前辈的辛勤付出，让我们少走了很多的弯路！
