This just started to happen when i restarted computer...why当我重新启动计算机时,这才开始发生......为什么
I can't find anywhere where I am calling require()... maybe a plugin I installed?我在任何地方都找不到我调用 require() 的地方……也许我安装了一个插件?
In my case, had created a setupProxy.js file at project level, later i removed the configurations in it but not the file.就我而言,在项目级别创建了一个 setupProxy.js 文件,后来我删除了其中的配置,但没有删除该文件。 Hence the mentioned error in question was thrown.
因此,所提到的错误被抛出。 To resolve, try one of the following according to your need,
要解决,请根据您的需要尝试以下方法之一,
npm install -g npm
npm install & npm install -D
npm run start
Thanks to @Srinivas's response in the comment of the question.感谢@Srinivas 在问题评论中的回复。
Delete the generated setupProxy.js
file.删除生成的
setupProxy.js
文件。 If you want to use a proxy, instead add it into your package.json
file.如果您想使用代理,请将其添加到您的
package.json
文件中。
"proxy": "http://localhost:3000",
For a setupProxy.js
file like so:对于像这样的
setupProxy.js
文件:
const proxy = require('http-proxy-middleware');
// tells the browser to direct any relative reference paths to the below
// domain instead of our own
module.exports = function(app) {
app.use(proxy('/api/*', { target: 'http://localhost:3000' }));*/
};
When you are setting up a Proxy to make a request to a different server当您设置代理以向不同的服务器发出请求时
First Step is to install the dependency第一步是安装依赖
npm install --save http-proxy-middleware
Next create setupProxy.js file接下来创建 setupProxy.js 文件
setupProxy.js设置代理.js
const { createProxyMiddleware } = require('http-proxy-middleware');
module.exports = function(app) {
app.use(
'/api',
createProxyMiddleware({
target: 'http://localhost:3001',
changeOrigin: true
})
);
};
