代替

RUN npm install --global gulp -y

使用

RUN sudo npm install --global gulp -y

您尝试将gulp作为全局软件包从用户node(不是超级用户)安装.

You try to install gulp as a global package from user node (not superuser).

或在将用户切换到节点之前安装gulp.

Or install gulp before switch user to node.

USER node
RUN npm install --global gulp -y

boot2docker 基于 VirtualBox .出于安全原因，Virtualbox不允许共享文件夹上的符号链接.

boot2docker is based on VirtualBox. Virtualbox does not allow symlinks on shared folders for security reasons.

要启用符号链接，必须将 VBoxInternal2/SharedFoldersEnableSymlinksCreate/SHARE_NAME 设置为 1 . (此处是描述如何在Vargrant上进行操作的链接: Symbolic链接和Vagrant中的同步文件夹)

To enable symlinks You must set VBoxInternal2/SharedFoldersEnableSymlinksCreate/SHARE_NAME to 1. (Here is link to description how to do it on Vargrant: Symbolic links and synced folders in Vagrant)

VBoxManage setextradata VM_NAME VBoxInternal2/SharedFoldersEnableSymlinksCreate/SHARE_NAME 1

替换VM_NAME和SHARE_NAME，然后重新启动VirtualBox.

Replace VM_NAME and SHARE_NAME and restart VirtualBox.

另一种解决方案是将--no-bin-link添加到npm:

Another solution is add --no-bin-link to npm:

RUN npm install -g bower --no-bin-link
RUN npm install --global gulp -y --no-bin-link

编辑2

默认情况下，Windows 7安全策略不允许创建符号链接，因为它是潜在的安全威胁.如果用户不在Administrators组中，请运行 secpol.msc 并导航至本地策略-用户权限分配，然后将您的用户添加到创建符号链接.

EDIT 2

By default Windows 7 security policy does not allow creating symlinks as it's a potential security threat. If user is not in Administrators group run secpol.msc and navigate to Local Policies-User Rights Assignments and add your user to Create symbolic links.

如果您的用户属于Administrators组，则以以管理员身份运行开始VirtualBox.

If your user belongs to Administrators group then start VirtualBox with Run as Administrator.
