J'essaie d'exécuter la commande ci-dessous, mais malheureusement, je rencontre des erreurs.
$ gulp build
Dans mon terminal et j'obtiens cette erreur d'assertion. J'ai désinstallé node et NPM, puis réinstallé à l'aide de brew - . Comment désinstaller complètement Node.js et réinstaller depuis le début (Mac OS X) avec ces étapes. La version de mon noeud est la version 10.5.0 et la version de npm est 6.1.0
.
Mon système est MacOS High Sierra10.13.2

Gulp 4.0 a modifié la manière dont les tâches doivent être définies si la tâche dépend d'une autre tâche à exécuter. Le paramètre list est obsolète.
Un exemple de votre fichier gulpfile.js serait:
// Starts a BrowerSync instance
gulp.task('server', ['build'], function(){
browser.init({server: './_site', port: port});
});
Au lieu du paramètre list, ils ont introduit gulp.series()
et gulp.parallel()
.
Cette tâche devrait être changée en quelque chose comme ceci:
// Starts a BrowerSync instance
gulp.task('server', gulp.series('build', function(){
browser.init({server: './_site', port: port});
}));
Je ne suis pas un expert en cela. Vous pouvez voir un exemple plus robuste dans la documentation gulp pour exécuter des tâches en série ou cet excellent billet de blog de Jhey Thompkins.
Abaissez votre version de gulp dans le fichier package.json à 3.9.1-
"gulp": "^3.9.1",
https://fettblog.eu/gulp-4-parallel-and-series/
Parce que gulp.task(name, deps, func)
a été remplacé par gulp.task(name, gulp.{series|parallel}(deps, func))
.
Vous utilisez la dernière version de gulp mais un code plus ancien. Modifiez le code ou rétrogradez.
Je reçois la même erreur en utilisant Gulp. La solution consiste à passer à la version 3.9.1 de Gulp, aussi bien pour la version locale que pour la version CLI.
