使用github Actions将React应用发布到Github Pages

我做了一个简单的Reactjs应用，现在我想在gh页上发布它。我按照此Facebook教程进行了部署，并且也从我的PC上进行了部署。但是现在，我考虑使用Github Actions来部署到master分支的每次推送上，而不是每次手动部署它。所以我写了下面的动作。

name: gh pages publish

on:
  push:
    branches: master

jobs:
  build:
    runs-on: ubuntu-latest

steps:
  - uses: actions/checkout@v2
  - uses: actions/setup-node@v1
    with:
      node-version: 12
      registry-url: https://registry.npmjs.org/
  - name: publish package
    run: |
      yarn
      npm run deploy

但是此操作失败，因为它要求用户输入用户名和密码。

> gh-pages -d build
fatal: could not read Username for 'https://github.com': No such device or address

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] deploy: `gh-pages -d build`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the [email protected] deploy script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/runner/.npm/_logs/2020-06-21T07_07_19_700Z-debug.log
##[error]Process completed with exit code 1.

我怎样才能解决这个问题？

编辑：这是package.json文件
