Cannot find module 'vscode' in language server extension

Question

We made a copy of the lsp sample project, and in server.ts we are importing the @types/vscode package to access the Range interface when creating Diagnostic instances. However, when launching the client we get this error from the server:

Error: Cannot find module 'vscode'
Require stack:

    '/Users/gvalenc/git/Nick-Steinhauser/vscode-lsp-fork/server/out/server.js'
  ]
}

Here is the package.json for the client. The others are very similar.

{
  "name": "test-lib",
  "description": "test-lib",
  "author": "me",
  "license": "MIT",
  "version": "0.0.1",
  "publisher": "vscode",
  "repository": {
    "type": "git",
    "url": ""
  },
  "engines": {
    "vscode": "^1.63.0"
  },
  "dependencies": {
    "@types/vscode": "^1.67.0",
    "vscode-languageclient": "^7.0.0",
    "yaml-language-server": "^1.7.0",
    "log4js": "^6.4.4"
  },
  "devDependencies": {
    "@tsconfig/node16": "^1.0.2",
    "@vscode/test-electron": "^2.1.2"
  }
}

Here is the client's tsconfig.json (the others are about the same).

{
  "$schema": "https://json.schemastore.org/tsconfig",
  "extends": "@tsconfig/node16/tsconfig.json",
  "compilerOptions": {
    "esModuleInterop": true,
    "declaration": true,
    "declarationMap": true,
    "sourceMap": true,

    "rootDir": "src",
    "strict": true,
    "noUnusedLocals": true,
    "noImplicitReturns": true,
    "forceConsistentCasingInFileNames": true,
    "target": "esnext",
    "module": "CommonJS",
    "moduleResolution": "node",
    "types": ["node", "vscode"]
  },
  "include": ["src"],
  "exclude": ["node_modules", ".vscode-test"]
}

Tried deleting all the node_modules folders and reinstalling and recompiling. Am I missing something? Also tried different ways to import (with star and specifically just Range ).

My versions:

Answer 1

尝试将“@types/vscode”移动到 devDependencies

Answer 2

Turns out the vscode package can't be used in the language server. Instead we now use Range.create and Position.create from the vscode-languageserver package to create the Diagnostic instances.
