仅在一个文件中使用 ESLint “require is not defined”时如何解决？

Question

When I use require in my JavaScript, I get a warning from eslint, "require is not defined eslint(no-undef)".

Except for this one file, all the files in my project uses the browser env , which is set in my .eslintrc .

How can I make an exception and specify a node env for just this one file?

var fs = require('fs');
var path = require('path');

// my code

Similar to how you can override eslint rules with a code comment at the top of the file, you can also override the environment:

/* eslint-env node */

var fs = require('fs');
var path = require('path');

// my code

Setting the node environment will make it so that node features like require and __dirname are not treated as undefined.

See Specifying Environments in the eslint documentation.
