如图所示安装Grunt,我首先使用npm install -g grunt-cli全局安装了grunt-cli,现在我正在尝试执行npm install,但只是出错：

我刚刚将项目复制到非共享文件夹中,然后再次启动npm install.它奏效了.所以,它似乎是一个共享文件夹问题.但到底是什么？ Symlinks are enabled对于这个共享文件夹,我以管理员身份启动了VM(当我在安装Bower时出现类似问题时,它有所帮助).

是什么导致了这些错误以及如何解决这个问题？

Environment: VirtualBox with Debian guest system and Windows 7 host system.

编辑

现在(我想我在非共享文件夹中成功执行了npm安装后)我发现了不同的错误：

当我以常见方式启动VM时：
