【问题描述】：

我想在 npm 和 webpack 的帮助下使用 React 构建一个网站。我已经在我的机器上安装了 npm，现在我正在尝试在我的机器上安装 webpack。我运行了以下命令：

npm i webpack -S

但随后它会引发错误。请在下面找到错误日志：

npm http 200 https://registry.npmjs.org/is-buffer
npm http GET https://registry.npmjs.org/is-buffer/-/is-buffer-1.1.5.tgz
npm http 200 https://registry.npmjs.org/is-buffer/-/is-buffer-1.1.5.tgz

如果有帮助，还可以在下面找到 package.json 文件：

{
  "name": "React",
  "version": "1.0.0",
  "description": "Building website using React with help of npm and webpack",
  "main": "index.js",
  "scripts": {
    "test": "karma start",
    "start": "node server.js",
    "_comment": "start in the above line tells heroku how to start our app"
  },
  "author": "Tushar",
  "license": "XYZ"
}

你能帮我解决这个问题吗？

【问题讨论】：

对 webpack 一无所知。但是你试过npm install -g sync-exec吗？
是的，我试过了，但没用。
得到以下错误：npm ERR！错误：EACCES，mkdir '/usr/lib/node_modules/sync-exec' npm ERR！ { [错误：EACCES，mkdir '/usr/lib/node_modules/sync-exec'] npm ERR！错误号：3，npm 错误！代码：'EACCES'，npm 错误！路径：'/usr/lib/node_modules/sync-exec'，npm ERR！ fstream_type：'目录'，npm ERR！ fstream_path: '/usr/lib/node_modules/sync-exec', npm ERR! fstream_class：'DirWriter'，npm 错误！ fstream_stack：npm 错误！ ['/usr/lib/node_modules/fstream/lib/dir-writer.js:36:23'，npm ERR！ '/usr/lib/node_modules/mkdirp/index.js:37:53',
您可能想看看这个问题，因为您的权限似乎有问题，或者您使用错误的用户安装 nmp 模块...stackoverflow.com/questions/16151018/…

【解决方案1】：

如果我正确阅读了错误，您似乎使用的是非常旧版本的 node 和 npm。尝试将它们更新到 LTS 甚至最新版本。

您可以获取最新版本和/或安装说明here。
