I originally arrived at Bower Github Issue #991 a victim of an ENOENT while running continuous integration builds on Circle CI.

The inconsistencies are loud and clear while reading this thread; I appreciated the perspective of @AnthonySteele also encountering the issue in CI- he points out that many of the fixes proffered in these comments are brittle.

I believe we are all the victim of Race Conditions as Bower attempts to solve the dependencies in our bower.json file. So I'm going to push a build through my CI with @yjaaidi fix of separating the cache and registry.

However, I also want to point out something else worth fixing (thanks infinite as always @sindresorhus ). My original bower.json had a resolutions clause that originally slipped in when, during a previous bower install, I encountered a message Unable to find a suitable version for angular and at that time I opted to bump up to 1.3 and Prefix the choice with ! to persist it to bower.json. How lazy of me!

By simply reading very very carefully the message Bower was giving me, I'm able to untangle the dependencies:

Unable to find a suitable version for angular, please choose one:
    1) angular#1.2.15 which resolved to 1.2.15 and is required by angular-cookies#1.2.15, angular-resource#1.2.15, angular-route#1.2.15, angular-sanitize#1.2.15 
    2) angular#~1.2 which resolved to 1.2.15 and is required by qurrus-web 
    3) angular#1.0 - 1.2 which resolved to 1.2.15 and is required by angular-flash#0.1.13 
    4) angular#>=1 which resolved to 1.2.15 and is required by angular-bootstrap#0.10.0 
    5) angular#>= 1.0.7 which resolved to 1.2.15 and is required by angulartics#0.14.15 
    6) angular#1.3.0-build.2549+sha.862e587 which resolved to 1.3.0-build.2549+sha.862e587 and is required by angular-mocks#1.3.0-build.2549+sha.862e587, angular-scenario#1.3.0-build.2549+sha.862e587

Prefix the choice with ! to persist it to bower.json

[?] Answer: 

The correct answer is, ^c !

So in my new bower.json I simply bump angular down to 1.2 across the board to support some of the less mature angular modules I still want to use. And this bower install runs fine on local without any error messages.

And... BOOM! Headshot. Circle CI is now OK.
