我尝试在回送(strongloop)Webapp中安装依赖项时出现Npm错误 [英] Npm errors while I try to install dependencies in loopback (strongloop) webapp

问题描述

我是NodeJS世界的新手.我已经创建了一个loopback(strongloop)Web应用程序，但是在尝试运行该应用程序文件夹中的npm install命令之后，我在终端机上获得了此输出(Ubuntu服务器14.04具有最新的更新-在一个流浪汉实例中)

I am new in the NodeJS world. I have created an loopback(strongloop) webapp, but after it I try to run the npm install command in the application's folder I get this output in the terminal (Ubuntu server 14.04 withd newest updates - in a vagrant instance)

这是由回送框架生成的package.json:

This is the generated package.json which has been generated by loopback framework:

{
  "name": "example-app",
  "version": "1.0.0",
  "main": "server/server.js",
  "scripts": {
    "pretest": "jshint ."
  },
  "dependencies": {
    "compression": "^1.0.3",
    "cors": "^2.5.2",
    "loopback": "^2.22.0",
    "loopback-boot": "^2.6.5",
    "loopback-datasource-juggler": "^2.39.0",
    "serve-favicon": "^2.0.1"
  },
  "optionalDependencies": {
    "loopback-explorer": "^1.1.0"
  },
  "devDependencies": {
    "jshint": "^2.5.6"
  },
  "repository": {
    "type": "",
    "url": ""
  },
  "description": "example-app"
}

我尝试使用sudo npm install运行，但是得到的结果完全相同.

I have tried to run with sudo npm install but I have gotten exactly the same result.

版本:

• 节点v4.1.0
• Npm v2.14.3
• 流浪者1.7.4
• Ubuntu Server 14.04.3(具有最新更新)

这是 npm日志文件，它很长.

如果您知道我的错误，请不要犹豫，只需回答:)

推荐答案

这是Vagrant/VirtualBox的问题.不幸的是，同步/共享的文件系统不支持符号链接.

This is a problem with Vagrant/VirtualBox. Unfortunately, the synced/shared filesystem doesn't support symlinks.

如果您不需要此功能，最简单的方法是在Vagrantfile中将其禁用:

If you don't require this functionality, the easiest thing to do is to just disable it in your Vagrantfile:

# ...
config.vm.synced_folder ".", "/vagrant", disabled: true
# ...

如果确实需要它，您现在就可以找到解决方法，因为您知道它与symlink支持有关，npm用来创建bins:-)

If you do require it, you may be able to find a work around now that you know it is a problem with symlink support, which npm uses for creating bins :-)

请参见 https://docs.vagrantup.com/v2/synced-folders /basic_usage.html 了解更多详情.
