Expected behavior
npm install works.

Minimal reproduction of the problem with instructions
package.json:

{
    "main": "webpack.mix.js",
    "private": true,
    "dependencies": {
      "vue": "2.7.14",
      "vue-template-compiler": "2.7.14",
      ...
    },
    "devDependencies": {
      "jest-vue-preprocessor": "^1.7.1",
      ...
    },
}
