"Npm Start" 不工作

Question

我正在制作一个网站，我使用命令 npm start 将它放在本地主机上。但是，在我在 Visual Studio 代码编辑器上创建两个工作区后，它突然停止工作。它只会给我一个错误。

这是错误的样子：

npm ERR! path C:\Users\audre\first-blog\package.json

npm ERR! code ENOENT

npm ERR! errno -4058

npm ERR! syscall open

npm ERR! enoent ENOENT: no such file or directory, open 'C:\Users\audre\first-blog\package.json'

npm ERR! enoent This is related to npm not being able to find a file.

npm ERR! enoent

npm ERR! A complete log of this run can be found in:

npm ERR! C:\Users\audre\AppData\Roaming\npm-cache_logs18-05-29T07_42_13_915Z-debug.log

我不知道那是什么意思。谁能帮我？谢谢！

编辑：我的 package.json 文件包含以下内容：

Answer 1

使用可以保护环境的流程管理器。

几个选项是

永远(https://www.npmjs.com/package/forever)

这样，您可以使用 forever start <mainfilename>

在本地主机上启动网站

PM2 (https://www.npmjs.com/package/pm2)

这样，您可以使用 pm2 start <mainfilename>

在本地主机上启动网站

使用流程管理器，您可以从环境规范中抽象出来，直到您需要更具体的东西。

Answer 2

ENOENT 表示，您所在的位置运行 npm start 命令目录不包含 package.json 文件。

首先，确保您在正确的目录中并且它有 package.json 个文件。

另外，如果没有package.json文件，可以使用npm init命令初始化。

如果不是这样，请随时发表评论以纠正我。

Answer 3

当所有其他方法都失败时，remove/reinstall node.js 完全。当您在所有节点 env 命令上到处都出现错误时，这意味着节点已损坏或以某种方式出错。

Answer 4

如果您的机器上有多个版本的 nodejs 并且是运行节点版本管理器 (nvm)，请务必在终端中正确设置您的版本。

例如。 nvm 使用 v9.5.0
