你好，我不知道为什么，但当我想启动或构建我的react应用程序时，它会让我内存不足。我在脚本中添加了--max_old_space_size=8192，但没有任何帮助。错误：
yarn run v1.22.5
$ react-scripts --max_old_space_size=8192 build

我遇到这个问题是因为我的项目中有大文件。
在.env文件的下面一行可以解决我的问题。
GENERATE_SOURCEMAP=false
或者你也可以试试：
"build": "GENERATE_SOURCEMAP=false react-scripts build",
"winBuild": "set "GENERATE_SOURCEMAP=false" && react-scripts build",
