用 conda 安装 jupyter-themes: 修改 ju

    安装方法

    • 安装

      若jupyter notebook是conda安装的,强烈建议用conda安装jupyterthemes,不然若用pip安装jupyterthemes,会出现多种依赖不匹配

      conda install -c conda-forge jupyterthemes
      

      若jupyter notebook是pip安装的,则

      pip install jupyterthemes
      
    • 配置

      终端下输入以下命令

      jt -t gruvboxd -T -N
      

      意为使用 gruvboxd 主题,打开顶部工具栏(Toolbar),显示文件名(Name)

      运行过程中可能会返回报错如下,这说明已经别的用户安装了jupyterthemes,并重建了/tmp/yacctab.py,故你无法重写这个文件,这并不运行你使用jupyter notebook的配色。你的配色设置,保存到 $HOME/.jupyter/custom/,不和他的配色设置冲突。

      WARNING: Couldn't create 'yacctab'. [Errno 13] Permission denied: '/tmp/yacctab.py'
      WARNING: Couldn't create 'yacctab'. [Errno 13] Permission denied: '/tmp/yacctab.py'

    • 配置文件

      配置文件保存到了 $HOME/.jupyter/custom/,下是四个配置和依赖文件current_theme. txt, custom.css, custom.js, fonts/,之后每次执行jupyter notebook启动notebook时,会加载此配置,看见你要的主题。

    依赖不匹配怎么解决

    若jupyter notebook是conda安装,却用安装pip安装jupyterthemes,会出现多种依赖不匹配,最终如下装一圈依赖,才能安装成功

    conda upgrade notebook libsodium
    pip install jupyterthemes
    pip install --upgrade --user nbconvert
    pip install --upgrade ipykernel
    

    以下是各个依赖不匹配的详解:

    Found existing installation: terminado 0.6

    执行pip install jupyterthemes时报错

    notebook 5.7.6 has requirement jupyter-core>=4.4.0, but you'll have jupyter-core 4.3.0 which is incompatible.

    Installing collected packages: lesscpy, terminado, pyzmq, jupyter-client, prometheus-client, Send2Trash, notebook, jupyterthemes
    Found existing installation: terminado 0.6
    Cannot uninstall 'terminado'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

    这是因为,上述操作中pip自动更新了notebook,但这个notebook是用conda而非pip装的,故依赖项terminado不对

    解决方法:

    conda upgrade notebook
    

    而后可正常安装

    pip install jupyterthemes
    

    ImportError: libsodium.so.23

    执行jupyter notebook,报错

    ImportError: libsodium.so.23: cannot open shared object file: No such file or directory

    这是由于jupyterthemes依赖的libsodium没有更新

    解决办法:

    conda update libsodium
    # 或
    conda install -c conda-forge libsodium
    

    ModuleNotFoundError: No module named 'nbconvert.exporters.base'

    运行notebook时,用浏览器成功打开notebook的目录网页,但无法打开/新建python3 的 notebook文件,命令行下报错

    ModuleNotFoundError: No module named 'nbconvert.exporters.base'

    [E 20:28:58.544 NotebookApp]

    这是因为,这是由于jupyterthemes依赖的nbconvert没有更新

    解决办法:

    pip install --upgrade --user nbconvert
    

    然后将$USER/.local/bin添加到PATH,即可实现上述运行

    ERROR:tornado.general: Uncaught exception in zmqstream callback

    运行notebook时,用浏览器成功打开notebook的目录网页,能成功打开/新建python3 的 notebook文件,但点运行,迟迟不运行,命令行下报错

    ERROR:tornado.general: Uncaught exception in zmqstream callback

    这是因为,这是由于jupyterthemes依赖的ipykernel没有更新

    解决办法:

    pip install --upgrade ipykernel
