我正尝试使用vscode-languageclient库作为打字稿，为jupyter实验室构建LSP（语言服务器协议）扩展。 vscode-languageclient模块似乎可以正确识别，但是它依赖于vscode模块，在构建jupyter实验室时webpack找不到该模块。
我已使用
将vscode模块添加到扩展中 jlpm add vscode
要使jlpm build工作，我必须将以下内容添加到我的package.json文件中：
"scripts": {
...
"postinstall": "node ./node_modules/vscode/bin/install"
}
"engines": {
"vscode": "^1.33.x"
}
这使jlpm可以构建扩展，但是在运行jupyter lab build时，我收到一个Webpack错误，提示它无法定位模块vscode（请参阅终端输出）。
在运行jupyter lab build之前，我尝试将其添加到jupyter lab的登台目录中的webpack.config.js文件中：
module.exports {
...
resolve: {
alias: {
vscode$: path.resolve(__dirname, "./node_modules/vscode")
}
}
}
但是，它并没有改变错误。
这些是我在index.ts文件中使用的import语句：
import { workspace} from 'vscode';
import {
LanguageClient,
LanguageClientOptions,
ServerOptions,
TransportKind
} from 'vscode-languageclient';
这是运行jupyter lab build的输出：
