Jupyterlab 0.31.8
Ubuntu 14.04
密谋3.0.0

我正在尝试安装Plotly jupyterlab扩展。

运行jupyter labextension install @jupyterlab/plotly-extension --debug会导致

我尝试过的是这里https://github.com/jupyterlab/jupyter-renderers/tree/master/packages/plotly-extension

的标准建议

我该怎么做？

Answer 1

尝试了很多东西后，我开始工作了。我的猜测是，这两件事中的一项（或两项）是使其起作用的原因：

1）升级到Jupyterlab 0.34.12

2）使用以下两行安装nodejs：

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - && \
apt-get install -y nodejs

Answer 2

尽管答案是可以接受的，但是如果仍然存在任何问题并且在代理连接后仍然存在，请尝试在npm config中设置代理。
例子->

npm config set http-proxy=""
npm config set https-proxy=""

jupyterlab / plotly-extension无法安装
