我正在设置本地服务器，并且正在使用npm run json:server运行服务器，但是出现以下错误：
npm错误！在jsonserver@1.0.0 json：server脚本'json-server --watch db.json'处失败。
不知道该如何解决？
我尝试更新npm update -g，但没有帮助。
也尝试过npm i -g npm
并使用npm i --save-dev json-server在本地安装json服务器
无济于事

谢谢您的帮助！

我认为问题是您正在将npm运行脚本的思想与启动json-server合并，并且尚未完全实现任何一个方面。以下是我尝试的步骤，假设您希望有一个运行脚本来启动json服务器：
db.json重命名为package.json ，因为这实际上是您的节点项目的package.json文件。您可能在运行npm init时创建了此文件。当您使用自定义脚本命令启动服务器时，该文件不是您要为json服务器模拟的json数据。db.json：
{
"posts": [
{ "id": 1, "title": "json-server", "author": "typicode" }
],
"comments": [
{ "id": 1, "body": "some comment", "postId": 1 }
],
"profile": { "name": "typicode" }
}
现在将自定义运行脚本命令更改为不包含特殊字符 。例如，在您的 package.json 中，更改以下内容：
"scripts": {
"json:server": "json-server --watch db.json"
},
收件人：
"scripts": {
"start": "json-server --watch db.json"
},
现在使用自定义脚本命令启动服务器：npm run start。此时，启动服务器应该没有任何错误。
现在，如果您转到http://localhost:3000/posts/1，则应获得以下json响应：
{ "id": 1, "title": "json-server", "author": "typicode" }
