Mi configuración:
- Windows 10
- NVM 1.1.7 para Windows
- nodo 12.14.1 con npm 6.13.4
- Angular 8.2.14 con @ angular / cli 8.3.22
Solo intento ejecutar la plantilla angular predeterminada:
> npm install -g @angular/cli # this installed the angular version mentioned above
> ng new test # Chose default options for the project
> cd test
> npm ci # lots of error messages
El último comando produce muchos errores en la salida (pero no falla el comando):
> fsevents@1.2.11 install C:\test\node_modules\@angular\compiler-cli\node_modules\fsevents
> node-gyp rebuild

Todos los errores están relacionados con fsevents
, node-gyp
y ejecutable de Python no se encontraron. Así es, no tengo Python instalado, pero no es un requisito previo para angular.
El comando en realidad sale con un código 0 (que indica éxito, además, ¡ ng build --prod
funciona después de eso!), Pero seguramente hay muchos errores en la salida.
Eliminar la node_modules
carpeta manualmente y ejecutarla en npm install
lugar de npm ci
producir una salida que es mucho más corta y sin ningún error. Además, no modifica el package-lock.json
archivo, lo que indica que están instaladas las mismas versiones de las dependencias.
Que esta pasando? ¿Por qué tantos errores al usar npm ci
pero ninguno al usar npm install
?
