【问题描述】：
我正在尝试将 MERN 应用程序部署到 Now(zeit.co)，但没有成功。当 Now 在部署期间尝试构建时，它会收到“sh: react-scripts: command not found”错误并记录以下内容：

Love nodemon? You can now support the project via the open collective:

我的应用架构是：
我用npm创建app，使用npx create-react-app client --use-npm创建React客户端，所以我不认为是yarn和npm冲突。
我的服务器 package.json 是：
{
(...)
"scripts": {
"start": "node index.js",
"server": "nodemon index.js",
"client": "npm run start --prefix client",
"dev": "concurrently \"npm run server\" \"npm run client\"",
"build": "npm run build --prefix client"
},
(...)
}
}
我的 client/package.json 是 create-react-app 的默认值：
{
"name": "client",
"version": "0.1.0",
"private": true,
"dependencies": {
"@testing-library/jest-dom": "^4.2.4",
"@testing-library/react": "^9.4.0",
"@testing-library/user-event": "^7.2.1",
"react": "^16.12.0",
"react-dom": "^16.12.0",
"react-scripts": "3.3.0"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},
"eslintConfig": {
"extends": "react-app"
},
"browserslist": {
"production": [
">0.2%",
"not dead",
"not op_mini all"
],
"development": [
"last 1 chrome version",
"last 1 firefox version",
"last 1 safari version"
]
}
}
为了确保，我尝试在我的 client 文件夹上运行 npm install，但它并没有起到多大作用。我检查了我的 package-lock.json 并且确定，react-scripts 在那里，所以我希望它也应该出现在 Now 尝试从 github repo 构建时，对吧？我还查看了我的 client/.gitignore，但它只是 create-react-app 的默认文件：
# dependencies
/node_modules
/.pnp
.pnp.js
# testing
/coverage
# production
/build
# misc
.DS_Store
.env.local
.env.development.local
.env.test.local
.env.production.local
npm-debug.log*
yarn-debug.log*
yarn-error.log*
我服务器的 .gitignore 文件也没有任何可能导致问题的内容，它只是忽略了 node_modules 和 .env。
如果有更多部署 MERN 应用经验的人可以帮助我，我将不胜感激。
