术语“CI=false”未被识别为 cmdlet、函数、脚本文件或可操作程序的名称

Question

我正在尝试 gitlab 的 CI/CD 并正在制作一个构建项目的 yml 文件。问题是我得到以下信息：

$ npm run build
 > myreactapp@0.1.0 build C:\GitLab-Runner\builds\QLuLhspz\0\I416547\s4-software-fun-frontend
 > react-scripts build
 Creating an optimized production build...
 Treating warnings as errors because process.env.CI = true.
 Most CI servers set it automatically.

现在它说警告设置为错误，所以我尝试在 yml 文件中添加CI=false：

stages: ["build", "test", "deploy"]

before_script:
    - npm install
    - CI=false

build:
    stage: build
    script: npm run build

test:
    stage: test
    script: npm run test

deploy:
    stage: deploy
    script: npm run start

但比它说的命令不被识别。是因为它不是一个powershell命令还是react.js使用了node-command？（无论哪种方式都不起作用）

尝试过的来源：

• npm 错误！代码 生命周期
• https://github.com/facebook/create-react-app/issues/3657

编辑：发现问题......而不是在 yml 文件中执行它，而应该在项目本身中完成。如何在React JS中设置环境变量..？

Answer 1

您需要设置环境变量并运行每个相关命令：CI=false npm run build和CI=false npm run build。

如果将其设置为before_script，GitLab CI 会尝试将其作为独立命令运行（实际上它只是设置一个环境变量）。

是因为它不是一个powershell命令还是react.js使用了node-command？

Powershell 仅适用于 Windows，而 GitLab CI 命令是在 Linux 上运行的 bash 命令。React 与 Node.js 无关，尽管 create-react-app 确实使用了它。设置的环境变量可以由任何代码读取，无论它是 Node.js 还是其他代码。
