意外的令牌错误：纱线本地包依赖性

Question

我目前正在使用称为react-vertical-tree的模块。我希望编辑Github存储库中的一些代码，并用我的项目对其进行测试。我使用yarn-link尝试将本地文件与项目链接，但出现错误：

“模块解析失败：意外的令牌（18：8）您可能需要适当的加载程序来处理此文件类型。”

我的package.json

{
  "name": "my-app",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@material-ui/core": "^4.2.0",
    "@material-ui/icons": "^4.2.1",
    "@types/jest": "24.0.15",
    "@types/node": "^12.0.12",
    "@types/react": "^16.8.23",
    "@types/react-dom": "16.8.4",
    "@typescript-eslint/eslint-plugin": "^1.11.0",
    "@typescript-eslint/parser": "^1.11.0",
    "eslint-plugin-promise": "^4.2.1",
    "eslint-plugin-react": "^7.14.2",
    "react": "^16.8.6",
    "react-dom": "^16.8.6",
    "react-scripts": "3.0.1",
    "react-vertical-tree": "../react-vertical-tree",
    "serve": "^11.0.2",
    "styled-components": "^4.3.2",
    "ts-essentials": "^3.0.0",
    "typescript": "^3.5.2"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject",
    "eslint-check": "eslint --print-config ./src/App.tsx | eslint-config-prettier-check"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "devDependencies": {
    "eslint-config-prettier": "^6.0.0"
  }
}

我尚未对react-vertical-tree文件进行任何编辑，所以我不确定出什么问题。

我尝试在package.json上修复我的配置，但没有任何帮助。
