搜索得出结论:镜像源的问题,要更换镜像源。
之前在搭建环境的时候,已经对 Laravel Sail 的镜像源定制过,所以更换起来很简单。
之前定义镜像源地址的文件是:
vendor/laravel/sail/runtimes/8.0/sources.list
deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
可以看出用的是阿里云的镜像源,我先是更换为清华大学的镜像源,结果失败。
第二次更换为中科大的镜像源,然后成功启动 Laravel 项目。
更换后的文件如下:
deb http://mirrors.ustc.edu.cn/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.ustc.edu.cn/ubuntu/ focal main restricted universe multiverse
deb http://mirrors.ustc.edu.cn/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.ustc.edu.cn/ubuntu/ focal-security main restricted universe multiverse
deb http://mirrors.ustc.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.ustc.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb http://mirrors.ustc.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse
deb-src http://mirrors.ustc.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse
deb http://mirrors.ustc.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.ustc.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
具体做法:先将vendor/laravel/sail/runtimes/8.0/sources.list
文件的内容清空,在将以上代码复制粘贴保存即可。
亲测成功启动 Laravel 项目,愉快地开始学习。
别看这个动作很简单,倒腾来倒腾去,也花了将近两小时,我什么时候才能转行成功啊。
