problems building `web/samples_index`

[ghost]

not sure if anyone tried to build it manually on latest dart (following the readme instructions), but as per https://dart.dev/tools/pub/cmd

the standalone pub command is deprecated

so even after installing via flutter pub global activate grinder, executing grind generate results in grind: 7: pub: not found

related: https://github.com/google/grinder.dart/issues/381 (includes OS, versions, etc)

Nice catch. Do you mind trying this command to see if it does the trick for you?

dart pub global activate grinder

If you have the Flutter SDK installed, the cached version of dart should be available in your path, which should make that command possible.

If it does work, I'll update the README to match.

the real problem is: grinder internally calls pub, so expects it to be on path

• inline aliasing pub to dart pub (within terminal session) – does not work ❌
• global alias pub='dart pub' in .profile – works ✅
• enclosing flutter pub $@ into a bash-script named pub – works ✅
• manually adding /usr/lib/dart/bin/ to $PATH evidently works too :shrug: – flutter only added $HOME/snap/flutter/common/flutter/.pub-cache/bin to the path on install

but i think the linked related issue with grinder itself should be resolved first

moving on..

webdev serve webdev could not run for this project. Could not find a file named "pubspec.yaml" in "~/.pub-cache/hosted/pub.dartlang.org/_fe_analyzer_shared-14.0.0".

b/c.. there is no such directory

sure, pub get _fe_analyzer_shared, done

webdev serve

ok, sure,

webdev serve --delete-conflicting-outputs Could not find an option named "delete-conflicting-outputs".

what? you JUST told me to run with that flag :facepalm:

as per https://github.com/dart-lang/webdev/issues/1177#issuecomment-723149986 , one flag is not enough, so

webdev serve web --verbose --debug-extension --enable-expression-evaluation -- --verbose --delete-conflicting-outputs --track-performance

it finally worked!

Thanks for the deep dive, and for the friction notes.

Over the next couple weeks, I'm going to be revisiting the samples index as part of some related work on maintaining our repo structure, and will revisit this as I'm doing it.

im kinda surprised dart/flutter projects dont have docker-ish "setup+test+run" on new empty VMs for every release, to ensure full integrity with every other part of the final system
