Grunt cannot find task `sass:foundation_scss` in v0.9.13

[abhidvnt]

I'm trying to generate documentation for a Swagger JSON generated using swagger-php, and am using the following command (it's a local npm install since I have to include it in version control, but the same thing happens when I install spectacle globally):

node node_modules/spectacle-docs/bin/spectacle.js -d "./docs/swagger.json" -t "./docs/html"

Schema:

                                        }

It gives me the following output:

I'm guessing there's something wrong with the versioning of grunt-sass? Or is it something with my installation?

[yyamano]

@echofoxxx It looks the same problem as #105 . Could you try to remove node_modules and rerun npm install?

[gcoombe]

I've encountered this same error. I removed my node_modules re-installed and still get the task not found errors.

[michaelherger]

I'm experiencing the same issue when installing as suggested running npm install -g spectacle-docs. Works when run from a repository clone.

[dsdenes]

I had this error when spectacle was installed both globally and locally.

In my case, specifying to run the local binary, solved the problem:

./node_modules/.bin/spectacle

[auscaster]

Hey guys, sorry you're having issues!

I've just made a bunch of updates to spectacle, and have pushed the release up to stable 1.0.0. I also tested installing spectacle globally and locally and was able to build my project successfully in each case, so hopefully this bug can be closed.

[auscaster]

The minimum node version now supported is 8, which is required by grunt-sass.

[kminehart]

I was just unsuccessful and got this same error.

Thanks for the update, let's squash this once and for all!

The actual cause of the error is because of a missing folder, which causes the task to show as not found:

>> Error: ENOENT: no such file or directory, scandir '/usr/lib64/node_modules/spectacle-docs/node_modules/node-sass/vendor'

Looks like its directly related to this issue node-sass: sass/node-sass#1579

Suggested fixes for anyone hitting this snag:

1. Make sure your node-sass version is greater than 3.7.0.
2. Delete node_modules and npm install again.
3. You can also try to rebuild node-sass like so:

npm update
npm install
nodejs node_modules/node-sass/scripts/install.js
npm rebuild node-sass 

[dapepe]

Worked for me!

[rlauriston]

I'm not sure if this is the same problem. spectacle -d swagger.yaml fails with:

Loading "sass.js" tasks...ERROR
>> Error: ENOENT: no such file or directory, scandir '/usr/local/lib/node_modules/spectacle-docs/node_modules/node-sass/vendor'
Task error: Error: Task "sass:foundation_scss" not found.

There is in fact no file or directory named vendor in /usr/local/lib/node_modules/spectacle-docs/node_modules/node-sass.

I tried rebuilding node-sass but get "command not found" for nodejs, though /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Aliases/nodejs exists.

node-sass is 4.8.1. OS X 10.12.6.

[auscaster]

This is fixed after updating grunt-saas and node-sass to support grunt 1.0.x
