Pub: Crash running pub lish from bleeding edge SDK

[munificent]

I'm running pub from within the bleeding edge Dart SDK at commit 93c290047778586c73fe93a72f59bcb69f33a6c5. I'm trying to publish pkg/dart_internal, and when I try, I get:

~/dev/dart/sdk/pkg/dart_internal (master) → pub lish

I don't know if it's related, but yesterday I consistently hit a different NPE running pub publish with a version of pub that's ~1 week old (Pub 2.8.0-dev.16.0.flutter-0296286c03):

Another failure w/ publish? Hrm.

I saw https://github.com/dart-lang/pub/issues/2397 and fixed in https://github.com/dart-lang/pub/commit/737f055d0a1cfb348178dbde6bd13f06704bf6d4

but this looks different. And your SDK is after I merged the fix – at least I think.

[kevmoo]

@munificent – have you done a gclient sync to get the latest pub?

[sigurdm]

I believe this is fixed at sdk/HEAD with https://github.com/dart-lang/pub/pull/2400 .
I created: https://dart-review.googlesource.com/c/sdk/+/141246 to pull it into the sdk

[nekocode]

I meet the same issue, the flutter version is:

Flutter 1.16.3-pre.67 • channel master • https://github.com/flutter/flutter.git
Framework • revision be3a4b37b3 (16 hours ago) • 2020-03-26 18:08:05 -0700
Engine • revision b2bdeb3f0f
Tools • Dart 2.8.0 (build 2.8.0-dev.17.0 1402e8e1a4)

In this version, is there a temporary workaround to publish pub?

[kevmoo]

@nekocode – switch the the flutter dev/beta/stable channel to publish?

[munificent]

I had yesterday shortly before filing this, yes.

Hmm - you should be able to run an older (non-affected) pub version with a stable flutter.

$ flutter channel stable
$ flutter pub publish

If that doesn't work for some reason you could consider

cd tmp
git clone https://github.com/dart-lang/pub
cd project
FLUTTER_ROOT=$HOME/path/to/flutter $HOME/path/to/flutter/bin/cache/dart-sdk/bin/dart tmp/pub/bin/pub.dart publish

I have the same issue using pub from the latest build master:

It should go away when the next dart sdk is rolled into flutter containing #2400 🤞

[acoutts]

I had this error as well and just submitted this PR to fix it: https://github.com/dart-lang/build/pull/2671

[sigurdm]

If you look at the stack traces the errors are not the same, and not even in the same package.

I believe this issue is fixed.
