Bower: Bower update return me invalid-meta The "name" is recommended to be lowercase, can contain digits, dots, dashes

[stefensuhat]

I've tried to remove my installed last package that make my bower like that. But still no luck.

Looks like when I'm install my last package it I mistakenly paste an tab character:

bower install <space #tab> angular-input-stars-directive

Now every time I bower update it always return me this error even on my other project:

bower invalid-meta The "name" is recommended to be lowercase, can contain digits, dots, dashes

I've tried bower cache clean and reinstall the bower but still no luck.

Is there anyway can fix this?

Thanks

maybe remove bower_components?

[stefensuhat]

@sheerun So i need to remove bower_components on every project I have?.

[sheerun]

did it help?

[Siafu]

Having the same issue, no removing the bower_components folder did not help.

[stefensuhat]

renaming bower.json name without space solve the problem.

 {
    "name": "without-space",
    // your dependencies
  }

Leaving some feedbacks for others encountering this bug.

Updating from 1.7.2 -> 1.7.9 and having my package named madhouse/messenger hosted in a private (bitbucket).

{
  "name": "madhouse/messenger",
  ...
}

I was unable to run bower install anymore. Bower was just printing this warning and just exits right after that:

vagrant@ubuntu:/vagrant/sites/osclass/oc-content/plugins/madhouse_messenger$ bower install
bower                     invalid-meta The "name" is recommended to be lowercase, can contain digits, dots, dashes

As suggested above, clearing the bower_components/ folder fixed it. :)

This is just warning from bower. open your bower.json file and rename the "name" tag to get rid of this. It is recommended to have lowercase and digit. Special characters allowed are dot and dash.

[sumit1606]

Its just a warning,it can be easily avoided by changing the name of the file according to the bower instructions. eg make it lower case

[prakash-mishra-josh]

Clear bower_components folder

[slavikgreen]

i have {"name": "gfgAdminPanel"} , where is the dots???? Cleaning bower_components folder doesn't help((

[dardub]

If this is just a warning, why does it abort install? This is breaking a legacy application.

Edit: It looks like it still installed. I was expecting to see some confirmation after install.

[dardub]

@slavikgreen It can't have and capitalization anymore...

[RolandBarro]

I have received the same error " bower invalid-meta The "name"....

• I have changed the name into lowercase then run the command again

bower install

• just give that blank response, is that normal? I know it's not

[PavanRaj999]

TRY THIS
bower install --verbose --force

[RuiBaiaoFrost]

Removing the bower_components folder did it for me. Thanks

[AeonFr]

I have this issue while running bower init and bower install X.

I don't have a bower components folder nor a bower.json file in my project.

Using version 1.8.8 (I literally just installed it for the first time)

[AeonFr]

And in case it's any use, this is the output of bower install --verbose --force:

fcano@EKS-815 C:\xampp\htdocs\ae++
$ bower install croppie --verbose --force

Update: Using the command in a different folder worked fine. My current repo had a Bower_components folder (notice the first uppercase) and I removed it before running bower init.

Even though, the error persisted. I don't know if this might be related to Windows saving the old folder in some kind of "cache" or something.

Edit 2: Duh!! The issue was that the name of my repository's folder has a special character (is called ae++). Seems like this is actually related to issue #2294

[webgoon]

I put put a cwd line in my .bowerrcc as the he example gave: "cwd": "~/.path", This was giving me an issue removed that line and it worked like a charm again.
