问题描述
我正在尝试创建一个 JupyterLab 扩展，它使用打字稿.
I'm trying to create a JupyterLab extension, it uses typescript.
我已成功添加包@types/node"；允许我使用诸如 'require('http')' 之类的包.
I've successfully added the package "@types/node" allowing me to use packages such as 'require('http')'.
但是，一旦我尝试使用子进程，使用require(child_process")"，我在尝试构建扩展时就会收到以下错误.
But as soon as I try to use child process, using 'require("child_process")' I get the following error when trying to build the extension.
ModuleNotFoundError: Module not found: Error: Can't resolve 'child_process' in '/home/fionn/anaconda3/envs/jupyterlab-ext/share/jupyter/lab/staging/node_modules/jupyerlab_xkdc/lib'

推荐答案
放在package.json中
"browser":{
"child_process": false
}
你在使用 webpack 吗
