[英]TypeError: bn_js_1.default is not a constructor
Hello everone, i just implement bn.js in class validator DTO.大家好,我只是在 class 验证器 DTO 中实现bn.js。 And got some error like this:
并得到一些像这样的错误:
TypeError: bn_js_1.default is not a constructor at Object.transformFn TypeError: bn_js_1.default 不是 Object.transformFn 的构造函数
anyone can help me?任何人都可以帮助我吗? here's the DTO:
这是 DTO:
import BN from 'bn.js';
import { Transform } from 'class-transformer';
export class IWCreateNftCollectionV1ReqDTO {
@Transform(({ value }) => new BN(value.toString()))
royalties:BN;
}
And the package.json和 package.json
"dependencies": {
"@types/bn.js": "^5.1.0",
"bn.js": "^5.2.0"
}
Thanks谢谢
UPDATE Solved by adding bellow in tsconfig.json更新通过在tsconfig.json中添加波纹管解决
{
"compilerOptions": {
...
"esModuleInterop": true,
},
}
Seem like bn.js doesn't use default exports.似乎 bn.js 不使用默认导出。 You can either set
esModuleInterop: true
in your tsconfig
, or you should be able to do import * as BN from 'bn.js';
您可以在 tsconfig 中设置
tsconfig
esModuleInterop: true
,或者您应该能够import * as BN from 'bn.js';
if you don't want to modify that setting如果您不想修改该设置
Add the setting esModuleInterop: true
in the tsconfig file worked for me.在对我有用的 tsconfig 文件中添加设置
esModuleInterop: true
。
