无法从“/home/circleci/my-project”找到模块“@angular-devkit/build-angular”

Question

I am trying to integrate simple Angular project with CircleCi. When I run ng test, every test is passing, the project is also working fine with ng serve but when I push it to the GitHub CircleCi won't pass it because of:

#!/bin/bash -eo pipefail xvfb-run -a ng test --browsers=ChromeNoSandbox --code-coverage --watch=false

Could not find module "@angular-devkit/build-angular" from "/home/circleci/my-project". Error: Could not find module "@angular-devkit/build-angular" from "/home/circleci/my-project".

Here is config.yml file

version: 2
jobs:
  build:
    working_directory: ~/my-project
    docker:
    - image: circleci/node:10.10.0-browsers
    steps:
    - checkout
    - restore_cache:
        key: AngularCircleCI-{{ .Branch }}-{{ checksum "package.json" }}
    - run: sudo npm install -g @angular/cli
    - save_cache:
        key: AngularCircleCI-{{ .Branch }}-{{ checksum "package.json" }}
        paths:
        - "node_modules"
    - run: xvfb-run -a ng test --browsers=ChromeNoSandbox --code-coverage --watch=false
    - run: xvfb-run -a npm run e2e --protractor-config=protractor-ci.conf.js

And protractor-ci.conf.js

const config = require('./protractor.conf').config;
config.capabilities = {
  browserName: 'chrome',
  chromeOptions: {
    args: ['--no-sandbox']
  }
};
exports.config = config;

Answer 1

Through your terminal cd to your project directory folder, then type

ionic repair

then follow the message info that will appear by answering the Continue? Y if you accept/ N if not. That did the job for me.

Answer 2

I struggled with the same problem. My project was generated using the v1.6.0 of angular-cli.

1. npm update -g @angular/cli

2. editing my package.json changing the line "@angular/cli": "1.6.0" , to "@angular/cli": "^1.6.0",

3. npm update did the trick.
