JavaScript在yarn中构建，分配失败-yarn堆内存不足

Question

在本地环境中，我没有问题，但是在jenkins上使用以下脚本运行生产环境是有问题的：

yarn install --production
yarn build

构建过程大约需要5分钟，最后，jenkins退出，并显示以下控制台输出错误：

+ yarn install --production
yarn install v1.9.4

开始生成此错误的唯一更改是添加了2个节点依赖项：

编辑:另外，当我推送我的分支时，我从github得到了这个警告

​

​

所以我检查了yarn.lock，我可以看到它的版本是：

mem@^1.1.0:
  version "1.1.0"

但是我如何升级一个没有在package.json上定义的依赖项呢？

Answer 1

最后，我使用下面的代码：

https://stackoverflow.com/a/55378108/3541320

在我的package.json中，构建的脚本如下：

"build": "react-scripts --max_old_space_size=4096 build"

Answer 2

如果您使用内存较少(512MB)的服务器，则需要设置以下两项内容：

1-在react-scripts上设置更少的内存

"build": "react-scripts --max_old_space_size=256 build"

2-您可以禁用生成源图，如https://create-react-app.dev/docs/advanced-configuration put in .env文件中所述：

GENERATE_SOURCEMAP=false

Answer 3

有时，增加node.js的内存分配并不是您需要的解决方案。最常见的罪魁祸首是由循环依赖引起的递归。

Madge是一个工具，可以帮助您检测Nodejs/React应用程序中的循环依赖关系

添加到您的脚本

npm i -g madge

"madge": "madge  --image ./madge-graph.svg --extensions js,jsx,ts,tsx --circular .",
