如何安装@pyviz/jupyterlab_pyviz

Question

我试图运行在木星实验室的面板，但图形是不互动的。

我发现我需要‘安装这个软件包’，但是我无法安装它，我尝试过：

npm i @pyviz/jupyterlab_pyviz

out: 

  File "<ipython-input-21-385fb6412a4c>", line 1
    npm i @pyviz/jupyterlab_pyviz
        ^
SyntaxError: invalid syntax

这个：

# as found https://panel.holoviz.org/getting_started/index.html
conda install -c conda-forge jupyterlab
jupyter labextension install @pyviz/jupyterlab_pyviz

Out: 
  File "<ipython-input-22-e086b2168729>", line 1
    conda install -c conda-forge jupyterlab
          ^
SyntaxError: invalid syntax

最后：

conda install -c conda-forge jupyterlab_pyviz

OUT: 
PackagesNotFoundError: The following packages are not available from current channels:

  - jupyterlab_pyviz

刚刚发布了pyviz_comms 2.0，它自动捆绑JupyterLab扩展。只需使用pip安装pyviz_comms升级--升级或conda安装-c pyviz pyviz_comms。
