gruntjs - generator-angular: la tarea "karma" no se encuentra al llamar `prueba de ronco`

yeoman karma-runner

Question

Estoy tratando de configurar un entorno de desarrollo con Yeoman para AngularJS, instalé Yeoman de acuerdo con las instrucciones: sudo npm install -g yo bower grunt-cli generator-angular y estoy generando una nueva aplicación con yo angular .

Después de que se genera la aplicación, la ejecución del karma start inicia el servidor de karma, pero se ejecuta un resultado de grunt test en

Loading "grunt-karma.js" tasks...ERROR
>> TypeError: object is not a function
Warning: Task "karma" not found. Use --force to continue.
Aborted due to warnings.

Cómo puedo solucionar esto ?

EDITAR: algunos archivos (generados frescos de Yeoman)

Answer 1

A estaba teniendo el problema de No Encontrado.

Finalmente me doy cuenta de que era un problema con el puerto (el 8080 ya estaba usado)

en karma.config.js cambie el número de puerto:

// web server port
port: 9999,

Answer 2

Las respuestas obvias ya publicadas aquí fueron completamente inútiles para mí. Si la reinstalación de grunt-karma a través de npm no funcionó, y la carga explícita de la tarea en Gruntfile no ayudó, es posible que esté ejecutando una versión de npm anterior a 1.2.10.

Resulta que las versiones recientes de grunt-karma dependen de las dependencias entre pares , que se introdujeron en Node con la versión 8.19. Después de actualizar Nodejs (que también instala npm) y actualizar el karma globalmente, descubrí que también necesitaba editar mis archivos de configuración de karma. Deberá agregar frameworks: [''jasmine''], a karma.conf.js y eliminar las referencias a JASMINE y JASMINE_ADAPTER de la configuración de files .

Answer 3

despues de correr

npm install grunt-karma --save-dev

agregue la siguiente línea a Gruntfile.js

grunt.loadNpmTasks(''grunt-karma'');

esto funciona para mi

Answer 4

npm install grunt-karma --save-dev

o si lo necesitas

sudo npm install grunt-karma --save-dev
