推荐答案

创建React App签入的作者。

Author of Create React App checking in.

你绝对不应该安装 react-scripts 全球。

您还不需要 ./ node_modules / react-scripts / bin / in package.json 此答案暗示。

You absolutely should not be installing react-scripts globally.
You also don't need ./node_modules/react-scripts/bin/ in package.json as this answer implies.

如果你看到这个：

npm ERR! UpScore@0.6.0 start: `react-scripts start`
npm ERR! spawn ENOENT

It只是意味着在安装依赖项时出错了他第一次。

It just means something went wrong when dependencies were installed the first time.

我建议你做这三个步骤：

I suggest doing these three steps:



1. npm install -g npm @ latest 更新npm，因为它有时会出错。


2. rm -rf node_modules 删除现有模块。


3. npm install 重新安装项目依赖项。


1. npm install -g npm@latest to update npm because it is sometimes buggy.
2. rm -rf node_modules to remove the existing modules.
3. npm install to re-install the project dependencies.

这应解决问题。

如果没有，请提交问题，其中包含指向您的项目以及Node和npm版本的链接。

This should fix the problem.
If it doesn't, please file an issue with a link to your project and versions of Node and npm.
