只有/tmp/ GitHub操作-测试-2f311f40.sh: 1: jest: not

Question

我在GitHub操作中有一个管道，它暗示尽管它在本地工作，它还是找不到Jest。

如果我在本地运行npm run unit-tests，它可以正常工作，但是在CI中我得到以下错误：

> jest --group=unit --coverage --verbose

Answer 1

原因是您在本地机器上安装了jest全局命令，因此Jest命令可以在本地机器上使用，而在Github操作环境(容器)中则不适用，因此您必须用方法来修复它：

1.将jest安装在Github动作环境中。

  jobs:
  unit-test:
    name: unit-test
    runs-on: ubuntu-latest
    steps:
    - name: Checkout
      uses: actions/checkout@master
    - name: Unit Tests 
      run: |
        npm install
        npm install -g jest
        npm run unit-tests

2.或者在您的package.json文件中，将npm run unit-test更改为./node_modules/.bin/jest --group=unit --coverage --verbos以读取，我推荐第二种方法。

Answer 2

您可以在我的CI中看到，我有以下变量

  NODE_ENV: production

这导致npm只安装依赖项，而不安装devDependencies。当我删除这个env变量时，它就可以安装jest并正常使用它。
