Best way to set --max-old-space-size when JavaScript heap out of memory

github.com/npm/npm/iss…

So it turns out that instead of needing to alias npm or otherwise call node directly, you can increase Node's max heap size by setting the NODE_OPTIONS environmental variable (introduced in Node 8) as follows:

NODE_OPTIONS=--max_old_space_size=8192

Usage with NPM scripts:

"scripts": {
    "start": "cross-env NODE_OPTIONS=--max_old_space_size=8192 webpack"
}

或者,每次都在执行npm命令前执行一次

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