在JupyterLab设置Py3JS

Question

我在jupyter实验室安装Py3JS。 Jupyter实验室是使用conda安装的，但是在Windows7上运行的pythreejs安装存在问题。你知道吗

>>> conda --version 
4.6.14
>>> jupyter lab --version
0.32.1
>>> conda list pythreejs
pythreejs, version=2.0.2, build=py36_1001

当我打开jupyter实验室时，我得到一个弹出的错误：

Build Recommended JupyterLab build is suggested jupyter-threejs needs to be included in build jupyterlab-datawidgets needs to be included in build

我单击build and get：

Build Failed please run 'jupyter lab build' on the server ...

我以admin（conda在程序文件中）的身份在cmd行上运行“jupyter lab build”，节点开始工作，直到它冻结在以下位置：

_? jupyter-threejs@file:../extensions/jupyter-threejs-2.0.3.tgz_

有什么建议吗？你知道吗
