【问题描述】：

这是我第一次使用 nodejs，运行npm run start 命令时出现以下错误。 node 和 npm 之间是否存在版本兼容性问题？我可以看到结尾行表明这不是 npm 的问题。

【问题讨论】：

能否提供package.json文件？
尝试运行npm install，然后运行npm run start。我猜nodemon还没有安装
@ndemasie 你是对的，nodemon 没有安装，我试过npm install nodemon 并且成功了！
@palash，如果你没有看到nodemon，请运行npm list -g --depth=0，然后运行npm install -g nodemon
@ndemasie 它只与 npm install demon 一起使用，但 nodemon 在我使用 npm install -g nodemon 之后仅在 npm list -g --depth=0 中可见

【解决方案1】：

正如@ndenasie 所说，nodemon 没有安装。尝试运行npm install -g nodemon，然后运行npm run start，它应该可以工作。
