build_web_compilers not within constraints

[johnniwinther]

Trying to run my web/index.html from within IntelliJ I get the following error:

dart-sdk\bin\pub.bat global run webdev daemon web:53322 --launch-app=web/index.html
webdev could not run for this project.
The `build_web_compilers` version – 2.11.0 – is not within the allowed constraint – >=2.12.0-dev.1 <3.0.0.

It worked yesterday and I have no clue where the >=2.12.0-dev.1 <3.0.0 constraint comes from, it doesn't match the any constraints in my pubspec.yaml.

@jakemac53 Do you have any idea what has happened ? 2.12.0-dev.1 is still in the future, right?

The problem is webdev 2.6.0, released on Sep 8, 2020.

You have to manually downgrade webdev to 2.5.9 till the error is fixed.

pub global activate webdev 2.5.9
or
"D:\dart-sdk\dart-sdk 2.10.0-99.0.dev\bin\pub.bat" global activate webdev 2.5.9

worked for me.

cc @grouma @annagrin not sure what we want to do here - this version of webdev should have probably been released as a pre-release itself to avoid this type of issue :/

[jakemac53]

Probably the easiest fix would be to release a stable version of build_web_compilers?

Going to close this as a dupe of dart-lang/webdev#1099

I'm using webdev 2.7.6 package and I'm facing the same issue and still, they did not fix this issue.

[jakemac53]

build_web_compilers is now on version 3.2.1 - if you can't update to a compatible build_web_compilers you will need to stay on an older webdev.

[HamzaTanveer78]

I'm using webdev latest version which is 2.7.6 but how did I know about the compatibility of "build_runner" and "build_web_compilers".

[jakemac53]

Webdev should be emitting a message about the incompatible version. Because it is a globally activated package, it can't actually enforce the dependency directly and has to rely on just emitting its own error.

Hello all 👋

Run the following command to activate webdev

pub global activate webdev

If you are still seeing the error then the pub cache is more than likely interfering with you updating to the latest webdev. To fix, simply remove your pub cache, like so:

rm -rf ~/.pub-cache/

and re-run pub upgrade and pub global activate webdev

Cheers!
