no body has this error anymore?

when i use ionic cordova build android ,everything is ok ,
when i use ionic serve also ok.
but when i user ionic cordova build android --prod, out of memory error …

Thanks for your reply, can you tell me how to add this parameter? or how to make it permanent somehow?

now i only user the follow build command:

ionic cordova build android --prod

how can i add > --max_old_space_size=4096 parameter?

i’m so sorry to you!!!

b) make the process use less memory.
How to do it

OK,I try like this
ionic cordova build android --prod --max_old_space_size=4096
the errors as:

Running app-scripts build: --prod --iscordovaserve --externalIpRequired --nobrowser

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

I am having the exact same issue. I do have 4gb RAM. I thought this was because of my low RAM.

can you give same Suggests,i tried the follow,but no effect

1.modify the package.json scripts

“build”: “node --max_old_space_size=4096 ./node_modules/.bin/ionic-app-scripts build”,
“ionic:build”: “node --max_old_space_size=4096 ./node_modules/.bin/ionic-app-scripts build”,

2.modify node_nodules.bin\ionic-app_scripts

#!/bin/sh
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")
case `uname` in
    *CYGWIN*) basedir=`cygpath -w "$basedir"`;;
if [ -x "$basedir/node" ]; then
  "$basedir/node --max_old_space_size=4096"  "$basedir/../_@[email protected]@@ionic/app-scripts/bin/ionic-app-scripts.js" "$@"
  ret=$?
  node --max_old_space_size=4096  "$basedir/../_@[email protected]@@ionic/app-scripts/bin/ionic-app-scripts.js" "$@"
  ret=$?
exit $ret
              
Undo your code and Try this once:
File: project\node_modules\@ionic\app-scripts\bin\ionic-app-scripts.js

Add code just below the #!/usr/bin/env node:
#!/usr/bin/env node --max_old_space_size=4096
              
can you give me a screenshot of ionic-app-scripts.js code?

i modify like follow ,but when memory use 14XX mb,it out of memory,it’s does not work for me…
