打字稿代码样式TS2539:无法分配给"execFile"，因为它不是变量 [英] typescript code style TS2539:Cannot assign to 'execFile' because it is not a variable

问题描述

我有一个密码

import * as path from 'path';
import * as globby from 'globby';
import { execFile } from 'child_process';
import * as util from 'util';
//import * as Promise from 'bluebird';
import * as fs from 'fs';

execFile = util.promisify(execFile);

当编译为js时

显示这样的错误日志

Error:(12, 1) TS2539:Cannot assign to 'execFile' because it is not a variable.

我应该以正确的方式重写代码以解决此问题，还是只保留它的原意

what should i rewrite code for fix this in right way, or just keep ingorne it

推荐答案

在compilerOptions中为tsconfig设置types，就像这样

Setting up types for your tsconfig in compilerOptions, like this

"compilerOptions": {
    "target": "es5",
    "lib": [ "es2015"],
    "types": ["node"],
    "module": "commonjs"
  }
