我正在本地主机上运行的管道代理上的Azure管道中运行docker构建任务。我正在尝试“运行jupyter labextension install @jupyter-widgets/jupyterlab-manager”。
在基础图像中：node=14.14.0jupyter=1.0.0jupyter-packaging = 0.7.12jupyter-resource-usage= 0.5.1jupyter_client = 6.1.7jupyter_console = 6.2.0jupyter_core = 4.7.0jupyter_server = 1.6.1jupyter_telemetry = 0.1.0jupyterhub = 1.3.0jupyterhub-base = 1.3.0jupyterlab = 3.0.12jupyterlab-git = 0.30.0b2jupyterlab-templates = 0.2.5jupyterlab_code_formatter=1.4.5jupyterlab_pygments = 0.1.2jupyterlab_server = 2.3.0
Dockerfile看起来像这样：

USER root
COPY files/.npmrc $HOME/.npmrc
RUN jupyter labextension install --no-build @jupyter-widgets/jupyterlab-manager .....

.npmrc看起来像这样：

always-auth=true
strict-ssl=false
registry=https://pkgs.dev.azure.com/org-name/proj-name/_packaging/proj-name/npm/registry/
https-proxy=the-proxy-url
proxy=the-proxy-url

管道执行以下任务：
1.在.npmrc上运行npmAuthenticate任务，以使用auth-token编辑.npmrc文件。
1.接下来运行docker build。Dockerfile指示将此修改后的.npmrc复制到$HOME并尝试安装实验室扩展
找到此主题：https://github.com/jupyter-widgets/ipywidgets/issues/1982#issuecomment-468716770我们使用jupyterlab v3。所以node〉=12是必需的。所以我将Dockerfile改为：

USER root
COPY files/.npmrc $HOME/.npmrc
RUN conda remove nodejs && conda install -c conda-forge nodejs=12 && conda list | grep nodejs &&\
jupyter labextension install --no-build @jupyter-widgets/jupyterlab-manager .....

也试过这个：https://stackoverflow.com/a/52484330/3575135.没有帮助
正常的“npm install @angular/cli”可以工作。但是实验室扩展给了我一段艰难的时间。在这一点上似乎什么都不起作用。
这是错误：
ValueError: "@jupyter-widgets/jupyterlab-manager" is not a valid npm package
救命啊！
