我是 Anaconda 的新手,最近在我的计算机上安装了 jupyter 实验室。但是,每当我尝试在本地 Jupyter Labs 实例上构建时,都会收到以下错误:
在 jupyter 实验室终端中运行的代码:
PS C:\Users\briakeit> jupyter lab build

最佳答案
我相信我已经找到了问题所在。我为一家公司咨询,我使用的是他们提供给我的电脑(我是电脑的管理员)。当我在我的个人计算机上执行相同的步骤时,它没有问题。
然后我在工作中切换到一个不同的、更开放的网络,并且构建能够无错误地完成。很明显,防火墙中有什么东西阻止了我进行构建。
关于Jupyter 实验室 : "RuntimeError: npm dependencies failed to install" When Building,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/60271242/
我是一名优秀的程序员,十分优秀!
