方案一

通过设置系统环境变量来实现

NODE_OPTIONS   --max-old-space-size=8192

查看是否设置通过可以使用以下命令，要新打开一个cmd窗口

node -e "console.log(v8.getHeapStatistics().total_available_size / 1024 / 1024 + ' MB')"

如果输出解决设置的值说明设置成功。

这里有个小坑，如果通过vscode的终端查看输出还是默认的2048则使用方案二设置

方案二

直接在vscode中设置环境变量

打开VSCode设置（Ctrl+,），搜索 Terminal > Integrated: Env，点击“Edit in settings.json”，添加：

"terminal.integrated.env.windows": {"NODE_OPTIONS": "--max-old-space-size=8192"
}

设置成功以后，新建一个终端运行下面命令看是否成功

node -e "console.log(v8.getHeapStatistics().total_available_size / 1024 / 1024 + ' MB')"

如果输出解决设置的值说明设置成功。

方案三

在项目或脚本中直接指定参数

可以直接在package.json的脚本中指定内存参数：

{"scripts": {"build": "run build node --max-old-space-size=8192"}
}
