Jupyter Labs:"RuntimeError:npm依赖项安装失败"建造时 [英] Jupyter Labs: "RuntimeError: npm dependencies failed to install" When Building

问题描述

我是刚开始使用Anaconda的人，最近刚在计算机上安装了jupyter实验室.但是，每当我尝试在本地Jupyter Labs实例上构建时，都会出现以下错误:

I'm new to using Anaconda and recently installed jupyter labs on my computer. However, any time I try to build on my local Jupyter Labs instance I get the following error:

在jupyter Labs终端中运行的代码:

Code run in jupyter labs terminal:

PS C:\Users\briakeit> jupyter lab build

输出:

每当我尝试使用此命令时(例如在安装新的扩展程序之后)，都​​会发生这种情况.根据conda，我在此环境中安装了npm v6.4.1，nodejs v10.13.0和yarn v1.22.0.我正在运行Jupyter实验室1.2.6.

This happens anytime I try using this command (e.g. after installing anew extension). I have npm v6.4.1, nodejs v10.13.0, and yarn v1.22.0 installed in this environment according to conda. I'm running Jupyter lab 1.2.6.

任何反馈，建议或帮助，将不胜感激.

Any feedback, suggestions or help would be greatly appreciated.

推荐答案

我相信我已经找到了问题.我为一家公司咨询，并且我使用的是他们提供给我的计算机(我是计算机的管理员).当我在个人计算机上执行相同的步骤时，它没有任何问题.

I believe I have found the problem. I consult for a company and I was using the computer they provided me (I'm an admin on the computer). When I followed the same steps on my personal computer, it worked with no issues.

然后，我在工作时切换到另一个更开放的网络，并且构建能够顺利完成.显然，防火墙中有某些内容或阻止我进行构建的内容.

I then switched over to a different, more open network at work and the build was able to complete without errors. Clearly there is something in the firewall or something that was preventing me from doing the build.
