我有一台新的2016款MacBook Pro 13英寸，我正试图让dart和dartium运行起来。但是，当我使用pubspec.yaml在目录中运行pub get时，我没有得到pubspec.lock文件或其他任何内容。
软件包声称正在下载，但是在最后一个软件包之后，我没有收到任何进一步的输出。
这是pub get

然后当我尝试运行pub build或pub serve时，
no pubspec.lock file found, please run "pub get" first
我通过自制软件安装了dart 1.15.0（我的团队使用的版本）。
编辑：我的主管克隆了我的分叉仓库，能够毫无问题地执行pub get和pub serve，因此pubspec.yaml文件或repo似乎没有问题本身。
答案 0 :(得分：2)
在我的防火墙设置中将pub添加到允许的连接并执行我的计算机的硬重启后，此问题已得到解决。
我认为这个问题是由于pub因防火墙而导致连接超时，并且没有警告而失败。
