typescript 找不到模块：错误无法解析“child_process”，如何解决？

Module not found: Error can't resolve 'child_process', how to fix?

提问by OneTwo

I'm trying to create a JupyterLab extension, it uses typescript.

我正在尝试创建一个 JupyterLab 扩展，它使用打字稿。

I've successfully added the package "@types/node" allowing me to use packages such as 'require('http')'.

我已经成功添加了包“@types/node”，允许我使用诸如“require(‘http’)”之类的包。

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.

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收到以下错误。
