执行命令时出错：node --max_old_space_size=3072 node_modules/@vue/cli-service/bin/vue-cli-service.js build

Question

I some projects in AWS codeBuild, the problem i have is that since yesterday i have been getting this error in the build

[Container] 2020/03/09 12:51:00 Running command node --max_old_space_size=3072 node_modules/@vue/cli-service/bin/vue-cli-service.js build --mode production

I know the probably the project is trying to use more than 3072Mb of ram, but i don't know why, i have another project that have more pages and components and it have not throw that error.

So here the questions

How can i know how much ram is using the node to build the vue project in local? How can i optimize the build process? The node modules has to do with this? this project with the error has more packages than the other one.

Answer 1

A few webpages such as following suggest that it is probably a RAM issue.

• https://github.com/npm/npm/issues/4008

The node command in the error message has the —- max-old-space-size flag which sets the memory limit to 3gb rather than the default of 512 mb.

• https://medium.com/@vuongtran/how-to-solve-process-out-of-memory-in-node-js-5f0de8f8464c

This 3gb value should match the compute type the build project:

• https://docs.aws.amazon.com/codebuild/latest/userguide/build-env-ref-compute-types.html

You maybe using 'build.general1.small' which has 3gb but node may not be able to allocate all of it.

So can you try the command with a lesser amount of memory reading, eg

$ node --max_old_space_size=2560 node_modules/@vue/cli-service/bin/vue-cli-service.js build --mode production

Or you can try to upgrade the compute type but that may incur a price increase.
