网络连接 ETIMEDOUT 以在 VM 中安装量角器

Question

背景_注意： 我已经在所有全局/主机上成功安装了量角器。但同样的方法在 VM 中不起作用。

也就是说，此问题仅出现在 Windows 7 虚拟机中，否则不会出现。 所有这些机器（VM、主机和单个机器）都具有相同的代理设置，我在 npm config 中到处都设置了相同的设置。

npm config set proxy http://proxy_server:8080
npm config set https-proxy http://proxy_server:8080

---

现在我尝试的程序：

1. 我在 Windows 7 远程桌面 (VM) 中，以非管理员用户身份登录
2. 我以管理员身份打开了 cmd 窗口。
3. 尝试将量角器安装为

npm install -g protractor

1. 此安装失败，日志和配置列表附在下面。
2. 尝试了Bower error tunneling socket could not be established, cause=Parse Error的所有可能答案 ==> 它们不适合我。

; userconfig C:\Users\test\.npmrc
registry = "http://registry.npmjs.org/"

; builtin config undefined

; node bin location = C:\Program Files\nodejs\\node.exe
; cwd = C:\Windows\system32
; HOME = C:\Users\test
; 'npm config ls -l' to show all defaults.

Answer 1

解决了。 当使用 VM 并且它具有某些代理集时，请使用全局代理（它是所有其他代理的根）。 所以，在安装量角器之前运行这两个命令：

C:\Windows\system32>npm config set registry "http://registry.npmjs.org/"
C:\Windows\system32>npm config set proxy http://global.proxy.alcatel-lucent.com:8000
