npm install - javascript heap out of memory

问题

When running npm install -g ionic I get the following error:

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

Is there a way to globally increase the node.js memory limit?

回答1:

You can launch NPM using :

node --max_old_space_size=8000 $(which npm) install -g ionic

As described here, the default is 4000 (4Gb).

I flagged this as a duplicate, but in case anyone happens across it, I posted the modern solution to this problem over at https://stackoverflow.com/a/48895989/4200039:

As of v8.0 shipped August 2017, the NODE_OPTIONS environment variable exposes this configuration (see NODE_OPTIONS has landed in 8.x!). Per the article, only options whitelisted in the source are permitted, which includes "--max_old_space_size".

So I put in my .bashrc: export NODE_OPTIONS=--max_old_space_size=4096

回答3:

Try, node --max-old-space-size=<size> where size is in megabytes.

回答4:

Run these commands

npm install -g increase-memory-limit

Run from the root location of your project:

increase-memory-limit

I had an incorrect prefix in my .npmrc file, just delete it.

prefix=D:\development\nodejs
