Visual Studio 2015 bower - not installed

问题

Using a Empty Template in Visual Studio 2015, the following configuration fails to install dependencies.

{
  "name": "ASP.NET",
  "private": true,
  "dependencies": {
    "bootstrap": "3.0.0",
    "bootstrap-touch-carousel": "0.8.0",
    "hammer.js": "2.0.4",
    "jquery": "2.1.4",
    "jquery-validation": "1.11.1",
    "jquery-validation-unobtrusive": "3.2.2"
  }
}

While the same configuration for a Web Application Sample template in ASP.NET completes successfully.

My colleagues are running into the same problem.

Is this a Known issue? Is there a work around? What am I missing?

Error in the output window is :

"C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\Web Tools\External\Bower.cmd" install --force-latest
bower bootstrap#3.0.0        ENOTFOUND Request to https://bower.herokuapp.com/packages/bootstrap failed: getaddrinfo ENOTFOUND

So I got this error tinkering around the configs again.

ECMDERR Failed to execute "git ls-remote --tags --heads https://github.com/twbs/bootstrap.git", exit code of #128

I ran into a similar error in VS 2015 RTM (not RC). This fixed for me:

Install git tools (if not already installed) from http://git-scm.com/download/win
In the command line enter the following command(or git bash if you did not add git to your PATH): git config --global url."http://".insteadOf git://
In VS menu Tools > Options.. > Projects and Solutions > External Web Tools
Uncheck $(DevEnvDir)\Extensions\Microsoft\Web Tools\External\git
Add C:\Program Files (x86)\Git\bin

Hope this helps.

Note: that I experienced this on a MVC 5 web app, not the new preview template but I am using Gulp/Bower/NPM tooling.

UPDATE 1 Although not a duplicate scenario the error messages are similar. I wonder if some override is done in the Web Application template somewhere? Would be good to find if thats the case. VS 2015 + Bower: Does not work behind firewall

UPDATE 2 I tried in an empty project after the above changes: bower bootstrap#3.0.0 not-cached git://github.com/twbs/bootstrap.git#3.0.0 bower bootstrap#3.0.0 resolve git://github.com/twbs/bootstrap.git#3.0.0

This is a bug. Expand the wwwroot/lib folder, and it's clear that the packages actually are loaded. Close/reopen the project, all appears well. We've opened a bug on this from your report. Thanks for an actionable description of the problem, sorry about the experience.

I also run in this problem with VS2015 3 and I did what Owen did but it didn't work for me.

What I did in the end was to

delete bower.json and .bowerrc files
delete bower_components and wwwroot folders.
added a new bower configuration file to the project
added again the dependencies in it.

It worked.

From what I saw in output window before deleting at the end the wwwroot folder if you try to add a new bower configuration file VS only installs bower if you add a new dependecy and also after that it checks in the wwwroot folder that the dependecy files aren't already installed (unfortunatelly I didn't save the output which was saying that it doesnt install the dependecy cause there is already a dependency with same version installed). This means that probablly only deleting bower_components and wwwroot folder and restoring packages could fix the issue.

May be some bower`s component is not installed. Remove and reinstall this component this via Bower Packege Manager. I had similar situatution after cloning repo. Ng-table lib was not restored and VS show me message in Sulotion Expolrer Bower - Not Installed. This manipulations helped me.

I just ran into this in VS2015.3. I don't have the time to dig into what is happening to cause the orphanage, but basically the folder under bower_components was identifying as a non-bower folder(?) and preventing bower install from installing the package. (I suspect an issue with VS and TS git repos.)

After trying the tests @deebo listed, I was not any closer. To get this back into a working state I performed the following steps:

Delete everything under bower_components
Run bower install again.

At this point all of my modules installed correctly. I hope this helps anyone else who runs into this.

回答6:

Usaly you just need delete bower_components folder in a project and do Bower/Restore Packeges. It`is some bower magic.

Instead of

{
    "jquery-validation": "1.11.1",
    "jquery-validation-unobtrusive": "3.2.2"
}

just use

{
    "jquery-validation": "*",
    "jquery-validation-unobtrusive": "*"
}

when you use "*" you are telling bower to install any version that is available on the nuGet packages
