我一直在尝试编译我的项目几个小时,我在Internet上进行了搜索,但是我仍然不明白为什么它不起作用。
我刚运行npx tsc
,但出现此错误:
$ npx tsc
src/index.ts:2:24 - error TS2307: Cannot find module 'React'.
2 import * as React from 'React';
~~~~~~~
Found 1 error.
tsconfig.json:

"target": "es6",
"module": "commonjs",
"esModuleInterop": true,
"lib": [

src / index.ts:
import lodash from 'lodash';
import * as React from 'React';
packages.json:
{
"files": [
"dist"
],
"devDependencies": {
"@types/lodash": "^4.14.144",
"@types/node": "^12.11.7",
"@types/react": "^16.9.11",
"lodash": "^4.17.15",

"typescript": "^3.6.4"
}
}
有什么作用?
答案 0 :(得分:0)
您可能应该将react
作为依赖而不是devDependency
安装。
另外,使react导入文件的第一行。
答案 1 :(得分:0)
除了安装之外,通过运行
作为依赖项npm i react
您可能想导入默认的导出模块。
import React from 'react';
在tsconfig.json
上,您可以将allowSyntheticDefaultImports
设置为true
。
"allowSyntheticDefaultImports": true
