Things to try:

尝试的事情：

1. make sure you have internet connection: ping 8.8.8.8
2. make sure you have DNS resolver working: ping www.google.com
3. make sure you can access registry.npmjs.org: ping registry.npmjs.org
4. make sure you can connect via https.

1. 确保您有互联网连接： ping 8.8.8.8
2. 确保您的 DNS 解析器正常工作： ping www.google.com
3. 确保您可以访问 registry.npmjs.org： ping registry.npmjs.org
4. 确保您可以通过 https 连接。

Try in your browser: https://registry.npmjs.org/

在浏览器中尝试：https: //registry.npmjs.org/

Make sure you are trying to connect to:

确保您尝试连接到：

• registry.npmjs.org

• registry.npmjs.org

and not to:

而不是：

• "registry.npmjs.org registry.npmjs.org:443"

• "registry.npmjs.org registry.npmjs.org:443"

or some other weird string composed of few hostnames, because it's weird that the resolver complains about a hostnames that includes a port number, which it shouldn't care about. Ok, I tested and it should look like this for hosts that are not found.

或其他一些由少数主机名组成的奇怪字符串，因为解析器抱怨包含端口号的主机名很奇怪，它不应该关心。好的，我进行了测试，对于找不到的主机，它应该看起来像这样。

Update

更新

From your comment to this answer it seems that you are notdirectly connected to the internet if you can't even ping 8.8.8.8.

从您对此答案的评论来看，如果您甚至无法 ping 8.8.8.8 ，您似乎并没有直接连接到互联网。

If you are using a proxy to access the Web, then you also have to configure npmto use it. Use:

如果您使用代理访问 Web，则还必须进行配置npm才能使用它。用：

npm config set proxy http://example.com:8080
npm config set https-proxy http://example.com:8080

but instead of http://example.com:8080use what you actually need in your company - ask someone or see how your browser is configured.

但不要http://example.com:8080使用您公司实际需要的东西 - 询问某人或查看您的浏览器是如何配置的。

To see your proxy configuration in Chrome, see this.

要在 Chrome 中查看您的代理配置，请参阅此。

If you canaccess https://registry.npmjs.org/in your browser but you cannotrun ping registry.npmjs.orgthen it means that your browser must be configured to use a proxy, or other programs than your browser must be restricted from using the internet.

如果您可以在浏览器中访问https://registry.npmjs.org/但无法运行，ping registry.npmjs.org则意味着您的浏览器必须配置为使用代理，或者必须限制浏览器以外的其他程序使用互联网。

In any case, you should ask someone in your company about it because most likely you either need to use a specific proxy or someone needs to lift the restriction from your npmand allow it to access the network.

在任何情况下，您都应该询问公司中的某个人，因为很可能您要么需要使用特定代理，要么需要有人解除您的限制npm并允许其访问网络。

The network access can be blocked by a firewall installed on your computer or a router in your network. It's hard to say without knowing the specific configuration in your company.

计算机上安装的防火墙或网络中的路由器可能会阻止网络访问。不知道贵公司的具体配置就很难说。

It happens because formidableis prone to severity vulnerability. So, you need to override that by running the above command.

发生这种情况是因为formidable容易出现严重漏洞。因此，您需要通过运行上述命令来覆盖它。

I had the same issue. The reason was the corporate proxy issue. Solution was to set the proxy setting as @rsp says.

我遇到过同样的问题。原因是公司代理问题。解决方案是像@rsp 所说的那样设置代理设置。

npm config set proxy http://example.com:8080
npm config set https-proxy http://example.com:8080

But later I face the same issue. This time reason was my password contains a special character.

但后来我面临同样的问题。这次的原因是我的密码包含一个特殊字符。

In this command you can't provide a password with special character

在此命令中，您不能提供带有特殊字符的密码

. So solution is to provide percentage encoded special character in the password.

. 所以解决方案是在密码中提供百分比编码的特殊字符。

For example # has to provide as %23

例如 # 必须提供为 %23

I spent over 5 hours trying to get rid of this message under Windows 8.1. So I would like to share my case and save someones time. I was not behind the proxy... but setting proxy helped to resolve the problem. So I go deep and found that issue was caused by Comodo Firewall... which blocked cmd since I was installing packages too fast (turning off and even closing Firewall did not help, which caused me so long to find the issue... seems like there was some other process of Firewall running in background). You may have same issue with any other firewall/antivirus installed so make sure that cmd is not blocked by them. Good luck!

我花了 5 多个小时试图在 Windows 8.1 下摆脱此消息。所以我想分享我的案例并节省别人的时间。我并不支持代理...但设置代理有助于解决问题。所以我深入研究发现问题是由 Comodo Firewall 引起的...它阻止了 cmd 因为我安装软件包太快（关闭甚至关闭防火墙都没有帮助，这让我很长时间才找到问题...似乎就像在后台运行其他一些防火墙进程一样）。您安装的任何其他防火墙/防病毒软件都可能遇到同样的问题，因此请确保 cmd 没有被它们阻止。祝你好运！
