node.js - Cannot find module 'ngx-bootstrap'

问题描述

I'm having an issue in my application with ngx-bootstrap whereby it now can't detect the module unless you specify the path

For example:

import { BsModalService, BsModalRef } from 'ngx-bootstrap';

produces "Cannot find module 'ngx-bootstrap'".

Removing the reference and checking quickfixes just replaces the reference with:

import { BsModalService, BsModalRef} from 'ngx-bootstrap/modal/public_api';

Obviously this isn't ideal as they should be available through ngx-bootstrap without specifying the folder, and i would have to go through dozens of components and change these references which shouldn't be necessary. Has anyone had this problem before?

I've already tried:

This was working fine yesterday. I'm not sure what I'm missing.

解决方案

根据ngx-bootstrap 文档，angular9 不支持这种导入。如果你想使用BsModalService，ButtonsModule等等，你必须将它们导入如下：

// RECOMMENDED
import { BsModalService, BsModalRef } from 'ngx-bootstrap/modal';
import { ButtonsModule } from 'ngx-bootstrap/buttons';

代替 ：

// NOT RECOMMENDED
import { BsModalService, BsModalRef , ButtonsModule } from 'ngx-bootstrap';
