在“/home/vagrant/.pub cache/hosted/pub.dartlang.org/protobuf-0.5.3”中找不到名为“pubspec.yaml”的文件

我正试图从一个流浪的虚拟机内部构建一个Dart项目。该项目实际上是使用IntelliJ从我的主机创建的，但我希望使用Vagrant VM的人当然能够构建该项目，并且通常能够使用Dart工具对Dart项目尽一切可能，这是我设置Vagrant VM进行开发的主要原因

因此，在我的来宾计算机中的Vagrant环境中，路径/Vagrant通常包含与Vagrant文件位于主机上的文件相同且同步的文件

我的Dart项目是在主机上的Dart angular client文件夹下创建的，该文件夹与VAGRANT文件处于同一级别。我可以从dart angular客户端内部和IntelliJ中从主机构建项目，但我的想法是能够从Vagrant机器内部构建项目

因此，当我尝试在guest vagrant VM的/vagrant/dart angular client下键入pub build时，我得到以下错误

Could not find a file named "pubspec.yaml" in "/home/vagrant/.pub-cache/hosted/pub.dartlang.org/protobuf-0.5.3"

其中/home/vagrant/基本上是guest vagrant VM的主目录。我试图从来宾计算机内部手动全局安装Dart包，正如人们所料，该包确实安装在/home/vagrant/.pub缓存下，因为据我所知，全局安装/激活的Dart包甚至放在我的主机中的该文件夹下

如何从Vagrant VM内部构建我的项目

编辑 按照Günter Zöchbauer的建议执行pub-get之后，当我运行命令pub-build now时，我获得

这似乎有点严重。我不知道是什么引起了这个问题酒吧，流浪汉，但这似乎是C++代码。这看起来像是堆栈损坏。。。这是在从主机构建项目之后发生的，但据我所知，每当我们尝试重建Dart项目时，如果构建存在，就会被替换

编辑2 我再次尝试重新加载并配置虚拟机，然后在其中使用ssh，并再次尝试构建Dart项目，结果类似：

确保在发布生成之前运行发布获取

确保虚拟机具有足够的RAM请参见

听起来您缺少pub-get命令或/home/vagrant/。pub缓存不知何故已损坏。如果确实运行了pub get，是否确定该命令在运行pub build之前已完成？这是每次在vagrant中生成之前重新创建的.pub缓存目录，还是保留了以前的版本？我不知道Vagrant@GünterZöchbauer哦，因为我对Dart非常陌生，我仍然需要学习该语言，我不知道我必须手动执行pub get，我认为pub build会自动执行该操作，以防依赖关系没有解决..不。需要显式调用pub-get。您在开发过程中就已经需要它了，例如在WebStorm中，可以自动完成导入的代码。@GünterZöchbauer好的，谢谢。请看我的编辑。可能会有帮助只是做了一个搜索并发布了第一个链接是的，基本上结合了这两个解决方案，分别解决了第一个和第二个问题。
