该dotenv模块应该将我的文件优先.env.local于我的.env文件，但事实并非如此。当我REACT_APP_API_BASE在两个文件中都进行了设置时，应用程序总是使用.env. .env.local如果我删除 中的匹配定义，它只会使用中的值.env。

.env

REACT_APP_API_BASE = 'https://api-staging.mysite.com/api'

.env.local

REACT_APP_API_BASE = 'https://api-qa.mysite.com/api'

该应用程序正在对https://api-staging.mysite.com/api/endpoint进行 API 调用。

我究竟做错了什么？

作为参考，我没有react-scripts直接运行，我使用的是 CRACO。

发布赏金五分钟后，我终于弄明白了......

我的一个文件require('dotenv').config();在顶部。显然，这是用主.env文件中的任何内容覆盖 CRA 找到的配置。从我的代码中删除该行后，一切正常。
