Angular 7 致命错误：接近堆限制的无效标记压缩分配失败 - JavaScript 堆内存不足

Question

我的项目很大。在上一个版本中，我添加了大量新功能。构建过程给了我这个错误日志。

更改 --max-old-space-size=4096 对我不起作用。

Answer 1

你能用下面的 prod 命令试试 --max-old-space-size=8192

node --max-old-space-size=8192 ./node_modules/@angular/cli/bin/ng build --aot=true --optimization=true --source-map=false

Answer 2

将 package.json 中的 npm 命令添加到如下脚本中：

“脚本”：{
“ng”：“ng”，
"start": "ng serve",
"go": "node --max_old_space_size=8192 ./node_modules/@angular/cli/bin/ng serve",
.
.

然后在命令行或终端中使用 npm run go

Answer 3

我认为主要问题是您需要使用下划线而不是破折号。

--max_old_space_size=4096

4096 可能不够，您可以按照建议尝试将其增加到 8192。
