EPROTO:使用ember new时的协议错误,符号链接'../semver/bin/semver'

Question

我有一个用ubuntu/trusty64盒子创建的Vagrant虚拟机(它运行Ubuntu 14.04.3 LTS(GNU/Linux 3.13.0-66-generic x86_64))和Ruby on Rails,Node.js(5.x,但之前是0.12)和Ember CLI.

我正在尝试通过运行创建一个新的Ember应用程序ember new frontend,它总是给我一些错误:

Successfully initialized git.

Error: EPROTO: protocol error, symlink '../semver/bin/semver' -> '/vagrant/emberrails/frontend/node_modules/ember-cli-dependency-checker/node_modules/.bin/semver'
    at Error (native)

为什么？我怎样才能解决这个问题？

当我尝试通过NPM自己安装一些软件包时会出现此问题,但后来我添加了--no-bin-links命令,一切都很好,但我没有这个选项ember new.

Answer 1

 –no-bin-links

-no-bin-links告诉npm不要创建任何符号链接.

Answer 2

如果您使用 VirtualBox 作为 vagrant 的提供者，您可以将以下内容添加到您的 Vagrantfile 中

config.vm.provider "virtualbox" do |v|
    v.customize ["setextradata", :id, "VBoxInternal2/SharedFoldersEnableSymlinksCreate/vagrant", "1"]
end
