jupyter - Jupyter Labs:构建时出现“RuntimeError: npm dependencies failed to install”
问题描述
我是使用 Anaconda 的新手,最近在我的计算机上安装了 jupyter labs。但是,每当我尝试在本地 Jupyter Labs 实例上构建时,都会收到以下错误:
在 jupyter labs 终端中运行的代码:
PS C:\Users\briakeit> jupyter lab build
输出:
[LabBuildApp] JupyterLab 1.2.5

An error occured.

每当我尝试使用此命令时都会发生这种情况(例如,在安装新扩展之后)。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。
任何反馈、建议或帮助将不胜感激。
解决方案
我相信我找到了问题所在。我为一家公司咨询,我正在使用他们提供给我的计算机(我是计算机上的管理员)。当我在我的个人计算机上按照相同的步骤操作时,它没有任何问题。
然后,我在工作中切换到一个不同的、更开放的网络,构建能够顺利完成。很明显,防火墙中有什么东西或者是什么东西阻止了我进行构建。
