Problem with upgrade to 1.2 (... npm-container: package.js:23:7: The isAsset option to addFiles is deprecated...)!

Update to release METEOR@1.2.0.2 is impossible:
While reading package from /D/meteor-app/cpanel/packages/npm-container:
package.js:23:7: The isAsset option to addFiles is deprecated. Use PackageAPI#addAssets instead.

This project is at the latest release which is compatible with your current package constraints.

Did you already update your mup package? If not, fire npm update mup -g on your console based here.

Thanks, I try npm update mup -g, but don’t work.
I use win 7.

I use meteorhacks:npm, npm-container.
Does It have problem with this?

Actually, npm-container is included during the installation of meteorhacks:npm, try removing npm-container, here’s the instructions on how to do it, link.

Excuse me, how to update in my project?

Theara@THEARA-PC D:\meteor-app\cpanel
meteor update

But don’t work.

You just remove npm-container as instructed on the repo if you’re using 1.2,

rm -rf packages/npm-container 
meteor remove npm-container

then update meteorhacks:npm, just run meteor update meteorhack:npm on your console

meteor update meteorhacks:npm

finally, run meteor

meteor

Now it show:

$ meteor update

To update one or more of these packages, pass their names to `meteor update`.                    

And then I check meteor --version is 1.1.0.3 in my project.
But the global version is 1.2

I had exact same problem…

what i did… i change the file manually. And i think that after that ur going to get at diferrent error on the same file… but you can also fix it manually.

After those 2 changes… probably is not the best solution, but it worked for me.

@theara, Yup, you have to manually update your packages if there’s available, if none, well, you have to wait for the package author.
