如何修复 Jupyter Hub No such file or directory: 'configurable-http-proxy'

English Deutsch 简体中文

问题：

尝试启动 Jupyter Hub 时，你看到类似这样的错误消息

jupyterhub_proxy_error.txt
[E 2021-06-18 13:07:48.462 JupyterHub proxy:711] Failed to find proxy ['configurable-http-proxy']
    The proxy can be installed with `npm install -g configurable-http-proxy`.To install `npm`, install nodejs which includes `npm`.If you see an `EACCES` error or permissions error, refer to the `npm` documentation on How To Prevent Permissions Errors.
[C 2021-06-18 13:07:48.462 JupyterHub app:2739] Failed to start proxy

      File "/usr/local/lib/python3.8/dist-packages/jupyterhub/proxy.py", line 707, in start

      File "/usr/lib/python3.8/subprocess.py", line 1702, in _execute_child
        raise child_exception_type(errno_num, err_msg, err_filename)
    FileNotFoundError: [Errno 2] No such file or directory: 'configurable-http-proxy'

解决方案

如 Jupyter Hub 安装文档所述，你需要安装 configurable-http-proxy npm 包才能使 Jupyter 工作：

install_configurable_http_proxy.sh
sudo npm install -g configurable-http-proxy

如果你尚未安装 npm，请参见我们关于如何在 1 分钟内在 Ubuntu 上安装 NodeJS 14.x LTS的文章或在 NodeJS 下载页面上为你的操作系统找到合适的发行版。
