javascript - React 启动和构建导致堆内存不足

问题描述

您好，我不知道为什么，但是当我想启动或构建我的 react 应用程序时，它会让我内存不足。我已将 --max_old_space_size=8192 添加到我的脚本中，但根本没有帮助。错误：

yarn run v1.22.5
$ react-scripts --max_old_space_size=8192 build

解决方案

由于我的项目中的大文件，我遇到了这个问题。

在 .env 文件中写下一行可以解决我的问题。

GENERATE_SOURCEMAP=false

或者您也可以尝试：

"build": "GENERATE_SOURCEMAP=false react-scripts build",
"winBuild": "set \"GENERATE_SOURCEMAP=false\" && react-scripts build",
