在通过 -c conda-forge 安装的 conda 安装中,尝试通过安装 nbextensions
jupyter contrib nbextension install --user
结果是
usage: jupyter-contrib [-h] [--debug] [--generate-config] [-y] [--log-level JupyterContribApp.log_level] [--config JupyterContribApp.config_file] [extra_args [extra_args ...]]
jupyter-contrib: error: argument --user: expected one argument
最近程序有变化吗?
