当从npm shell脚本运行时，为什么宗地命令失败，而直接运行时，宗地命令为何失败？

Question

I have the following prod script I've used previously on another, very similar project:

#!/usr/bin/env sh

GCC=$(npm bin)/google-closure-compiler

preGccBuildSteps () {
  rimraf prod dist && mkdir prod && ln -sfn ../../css prod/css && \
    spago build && spago bundle-module --main Metajelo.UI --to prod/index.prod.js && \
    cp static/index.* prod/
}


preGccBuildSteps || { echo 'preGccBuildSteps failed' ; exit 1; }
"$GCC" --js prod/index.prod.js --js_output_file prod/index.opt.js && \
  echo $(pwd) && \
  parcel build --public-url ./ prod/index.html

The echo $(pwd) is a recent addition to try to confirm I'm sane, but unfortunately, it prints out the expected directory when I run it using npm run prod and I get an error that seems not very helpful:

/wd/app
[Error: ENOENT: no such file or directory, scandir 'build'] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'scandir',
  path: 'build'
}
/wd/node_modules/parcel-luxe/lib/parser.js:44
    files.forEach(function (file) {
          ^

Note that /wd/app is the expected output of pwd .

OK, so clearly the issue must be with the last command, parcel build --public-url ./ prod/index.html .

But when I run this in the terminal directly, even just after the error with npm run prod , I actually get success:

brandon@4747aec8d9e1:/wd/app$ parcel build --public-url ./ prod/index.html

So why does it fail when run from npm run prod ?

Answer 1

Not an extremely satisfying answer, but, I realize now that I accidentally ran npm install outside of the container. Still, the node_modules were installed in the same place, but clearly this made a difference in some other way. After rm -fr node_modules && npm install inside the container, things are working again.
