在本地环境中我没有问题，但是使用此脚本在 jenkins 上运行生产环境：

yarn install --production
yarn build

构建大约需要 5 分钟，最后，jenkins 退出并出现此控制台输出错误：

开始产生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 收到了这个警告

在此处输入图像描述

所以我检查了一下yarn.lock，我可以看到那里的版本：

mem@^1.1.0:
  version "1.1.0"

但是如何升级未定义的依赖项package.json？

最后，我使用这个：

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

在我package.json的构建脚本中：

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

如果您使用内存较少（512MB）的服务器，则需要设置尝试两件事：

1 - 在反应脚本上设置更少的内存

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

2 - 您可以禁用源映射的生成，如https://create-react-app.dev/docs/advanced-configuration中所述，放入 .env 文件：

GENERATE_SOURCEMAP=false

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引起的。

Madge是一个工具，可以帮助您检测 Nodejs/React 应用程序中何时存在循环依赖

添加到您的脚本

npm i -g madge

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

也许您添加的 2 个依赖项占用了大量内存，它可以解释您从 jenkins 得到的错误。您是否尝试按照此处的说明增加分配给詹金斯的内存？

希望对您有所帮助！

看来我的情况很荒谬，但我不得不将 32 位节点替换为 64 位节点。

做 npm cache clean --force 为我解决问题

我可以像这样为我的一个项目修复它：

在新创建的 git 分支上运行：

npm run eject

这将创建许多文件并更新您的包 json（如果您没有更改它们，则为 start/test/build 命令）。

转到config/webpack.config.js并更新 TerserPlugin 选项属性 "compress" 和 "mangle" ：

new TerserPlugin({
   terserOptions: {
      ...
      compress: false,
      mangle: true,
      ...

这大大减少了构建时间和内存使用量......权衡是构建文件稍大（我的项目从 2.3Mo 变为 2.6Mo）。因此，在性能受限的情况下，您应该考虑它是否适合您的项目。

为什么会发生这种变化？由于Terser 文档中的以下信息，我尝试了此操作：

这并不为人所知，但对于大多数 JavaScript 来说，空格删除和符号修饰占缩小代码大小的 95% - 而不是复杂的代码转换。

我今天遇到了同样的问题。当我在本地机器上运行时，我的代码工作正常。但是当我将它部署到 netlify 时，它会显示您上面提到的错误。

我尝试在其他帖子上设置“max_old_space_size”变量和其他一些答案。但他们都没有为我工作。

就我而言，我在本地机器中的节点版本与 netlify 站点版本不同。

所以我用我的本地机器节点版本编辑了环境变量，构建成功完成。
