【问题描述】：

我正在尝试为 angular5 项目设置预提交 git 挂钩。我正在使用带有 lint-staged 的哈士奇。 Prettier 和 stylelint linters 运行良好。但是当 lint-staged 遇到 'ng lint' 时，它只会抛出错误：


    Project '/Users/sneha.vantamuri/Documents/customerportal/aviportal-ui/src/app/components/dashboard/dashboard.component.ts' could not befound in workspace.

这是我在 package.json 中的 husky 和 lint-staged 配置

    "hooks": {
      "pre-commit": "lint-staged"
    }
  },
  "lint-staged": {
    "*.{ts,scss,json}": [
      "npm run prettier:check",
      "npm run stylelint",
      "npm run lint",
      "git add"
    ]
  }

还有：

"scripts":{
"lint": "ng lint",
 "prettier:check": "prettier --config ./.prettierrc --check './src/**/*.{ts,scss,json}'",
 "stylelint": "stylelint \"src/**/*.scss\"",
}

"npm run prettier:check", "npm 运行 stylelint", 这两个命令运行正常但是 npm run lint 有错误

【解决方案1】：

花了几个小时后，我发现 projectName 没有正确传递。这就是 Workspace.getProject() 给出异常的原因。还知道，angular-cli > 5，需要明确指定项目名称，ng lint 命令才能使其与 lint-staged 一起使用。

为面临相同问题的人分享解决方案：

所以这里是解决方案：

    "*.{ts,scss,json}": [
      "npm run prettier:check",
      "npm run stylelint",
      "npm run lint **<yourProjectNamefromAngular.jsonfile> --files**",
      "git add"
    ]
  }
