docker-compose.yml中定义了一系列服务.这些服务已经开始.我只需要重建其中一个并在没有其他服务的情况下启动它.我运行以下命令:
docker-compose up -d # run all services
docker-compose stop nginx # stop only one. but it still running !!!
docker-compose build --no-cache nginx
docker-compose up -d --no-deps # link nginx to other services
最后我得到了旧的nginx容器.顺便说一句,docker-compose不会杀死所有正在运行的容器!
在执行composer install/update时,我从openssl得到以下错误:
无法下载" https://packagist.org/packages.json "文件:SSL操作失败,代码为1. OpenSSL错误消息:错误:14090086:SSL例程:SSL3_GET_SERVER_CERTIFICATE:证书验证失败无法启用加密失败打开stream:操作失败 https://packagist.org无法完全加载,包信息是从本地缓存加载的,可能已过期
我在用:

我不能再在版本3中使用getMainContext()和getSubcontext($ alias)了.在版本3中上下文之间进行通信的方式是什么.上下文特征是唯一的方法吗？

当我尝试使用AVR studio 4调试一小段代码时出现此错误:
Build failed... No build tools defined.
有人可以给我一些建议吗？
如何在div中居中对象内容？
.parent{
background-color:yellow;
}
.ob{
margin: 0 auto;
}
</style>
<div class="parent">
<object width="400" height="400" class="ob" data="helloworld.swf">
</object>
</div>
提前致谢!
