What's causing this error on upgrading to devextreme 16.2.x. App works and builds ok with devextreme 16.1.7.
回答1:
The problem is with windows environment, we need to allocate more memory in webpack/node process
in node_modules/.bin/webpack.cmd (set 8GB of memory)
@IF EXIST "%~dp0\node.exe" (
"%~dp0\node.exe" --max_old_space_size=8048 "%~dp0..\webpack\bin\webpack.js" %*
) ELSE (
@SETLOCAL
@SET PATHEXT=%PATHEXT:;.JS;=;%
node --max_old_space_size=8048 "%~dp0..\webpack\bin\webpack.js" %*
)
Thanks to Angelminster who provided the help
