我正在学习使用npm脚本自动执行Web开发任务。
以下是我的 ngOnInit() {
this.form = this.fb.group({
person: this.fb.group({
salutation: [{value: '', disabled: true}],
firstName: ['', Validators.required],
lastName: ['', Validators.required],
email: ['', [Validators.required]]
})
});
this.form.get('person').get('salutation').enable();
}
：
package.json但是，当我在命令提示符下运行{

"version": "1.0.0",
"description": "This is a website for Ristorante Con Fusion",
"main": "index.html",
"scripts": {
"start": "npm run watch:all",

答案 0 :(得分：0)
我猜你使用的是Windows。 Windows命令行不喜欢package.json中的单引号。请改用\"。
"watch:scss": "onchange \"css/*.scss\" -- npm run scss",
"watch:all": "parallelshell \"npm run watch:scss\" \"npm run lite\""
您还错过了--和npm之间的空格。
