Error: Cannot find module './util/resolveCommand'

Question

我认为由于 util npm 的问题，我无法再启动 npm。我尝试更新所有软件包并删除 util 并重新安装它。我该如何解决这个问题？

Error: Cannot find module './util/resolveCommand'

这是我的 package.json。

  "private": true,
  "dependencies": {
    "package.json": "^2.0.1",
    "react": "^16.1.1",

    "react-scripts": "1.0.17",
    "react-slick": "^0.15.4",

  },

    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  }
}

Answer 1

如错误所述，问题出在 react-scripts 使用的 cross-spawn 模块。问题不是因为 util 模块。

尝试以下操作以正确更新依赖项并查看它是否有效。

npm install -g npm@latest # to update npm.
rm -rf node_modules # to remove the existing modules.
npm install # to re-install the project dependencies.

你首先需要

npm 清理缓存力然后转到 git bash 如果您使用 windows 和运行
rm -rf node_modules 删除 node_modules 然后运行
npm 安装

Error: Cannot find module './util/resolveCommand'

Error: Cannot find module './util/resolveCommand'

node.js

npm

npm-install

npm-start
