需要通过我现有的 package.json 增加节点 max_old_space_size

Question

我继承的应用程序已经开始变大，我收到错误消息 CALL_AND_RETRY_LAST 分配失败 - JavaScript 堆内存不足。根据我的研究，我需要设置节点参数 max_old_space_size。

我目前正在运行 Node 7.8.0，因此我无法使用环境变量 NODE_OPTIONS，我尝试设置它但没有运气。我在下面粘贴了我现有的 package.json 文件，但我不知道在脚本部分中我可以放置参数 --max_old_space_size=2048

当内存达到 1.6 GB 左右时，节点进程通常会因上述错误而崩溃

2020 年 8 月 27 日更新：

我已尝试使用以下建议的解决方案：

"scripts": {
"high-memory": "node --max_old_space_size=2048 ./node_modules/.bin/ts-node",
"generate:client": "npm run high-memory -- ./swagger/generate-client.ts --baseApiUrl=http://localhost:5003",
"generate:client:prod": "npm run high-memory -- ./swagger/generate-client.ts --baseApiUrl=%API_URL%",

}

运行 npm start 时收到以下错误：

C:\Projects\Twiddy\TwiddyOps\Web\node_modules\.bin\ts-node:2
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")
          ^^^^^^^

Tell the author that this fails on your system:
npm ERR!     node --max_old_space_size=2048 ./node_modules/.bin/ts-node 
"./swagger/generate-client.ts" "--baseApiUrl=http://localhost:5003"

我就是这么用的：

"scripts": {
  "high-memory": "node --max_old_space_size=2048 ./node_modules/.bin/ts-node",
  "generate:client": "npm run high-memory -- ./swagger/generate-client.ts --baseApiUrl=http://localhost:5003",
  "generate:client:prod": "npm run high-memory -- ./swagger/generate-client.ts --baseApiUrl=%API_URL%",
}
