Dart Pub error on package install?

Question

Dart worked until I updated Editor and now I get errors for existing and new projects. I tried a complete reinstall of Dart. I get the following message when I run pub install on web-ui for a new project:

--- Jun 11, 2013 10:25:11 PM Running pub install ... ---
Pub install failed, [255] Unhandled exception:

#7      main (file:///e:/b/build/slave/dart-editor-win-trunk/build/dart/sdk/lib/_internal/pub/bin/pub.dart:61:30)

It's right that there is no "version" file in that directory from a clean install. I added that file and got the following message:

--- Jun 11, 2013 10:23:42 PM Running pub install ... ---

Pub install failed, [69] Resolving dependencies...

Failed NSS_Init call.

I get the following when I create a new project:

Any ideas?

Answer 1

Cannot open file 'C:\Users\Phloxicon\Documents\dart\dart-sdk\bin\version'

This looks your Dart installation is broken. That file should definitely be there when you install the Dart SDK, and pub can't work without it.

Are you building the SDK yourself, or just downloading a pre-built one?

Answer 2

Try pub update rather than pub install so that cached packages are updated where possible.

Then use Reanalyze Sources from the same Tools menu. Be sure to clear any logs before running the Reanalyze Sources so you can be sure it did a clean build.

If that doesn't get you completely clean, delete any packages directories you see in the project's tree, and any out directories that might be hanging around, as well as the pubspec.lock file. Then run pub install.

That usually gets me back to clean builds.
