ESLint - 'process' is not defined
提问by ArunKolhapur
I am using ESLinter for a simple node project. Below is the only code I have in index.js:
我正在将 ESLinter 用于一个简单的节点项目。下面是我在 index.js 中的唯一代码：
const express = require('express');
const app = express();
app.get('/', (req, res) => {
res.send({
hi: 'there'
});
});
const PORT = process.env.PORT || 5000;
app.listen(PORT);
I am using VSCodeeditor. It automatically runs ESLint for JS code.
我正在使用VSCode编辑器。它会自动为 JS 代码运行 ESLint。
In the IDE, I see below error for last but one line -
在 IDE 中，我在最后一行看到以下错误 -
[eslint] 'process' is not defined. (no-undef)
Any Idea what's wrong?
知道出了什么问题吗？

Thanks @FelixKling and @Jaromanda X for quick responses.
感谢 @FelixKling 和 @Jaromanda X 的快速回复。
I have fixed this with following config for .eslintrc.jsonfile-
我已使用以下.eslintrc.json文件配置修复了此问题-
{
"env": {
"node": true,
"commonjs": true
},
"extends": "eslint:recommended",
"rules": {
"indent": [
"error",
"tab"
],
"linebreak-style": [
"error",
"unix"
],
"quotes": [
"error",
"single"
],
"semi": [
"error",
"always"
]
},
"parserOptions": {
"ecmaVersion": 2015
}
}
When I got error I had "browser": trueinstead of "node": true. Simple mistake.
当我遇到错误时，我有"browser": true而不是"node": true. 简单的错误。

Adding "node": "true" to an existing list of environments will do the job, too
将 "node": "true" 添加到现有的环境列表也可以完成这项工作
"env": {
"node": true,
"commonjs": true,
"browser": true,
"es6": true
}

Add .eslintrc file to root of your project (if you don't already have one) and define globals to ignore
将 .eslintrc 文件添加到项目的根目录（如果您还没有）并定义要忽略的全局变量
{
"globals": {
"process": true
}
}
Make sure you use process.env though out the project but only in a single configuration file. Consider adding no-process-envrule.
确保在整个项目中使用 process.env，但仅在单个配置文件中使用。考虑添加no-process-env规则。
