npm错误！请求https://registry.npmjs.org/ngx-pagination失败，原因: getaddrinfo EAI_AGAIN registry.npmjs.org registry.npmjs.org:443

Question

当安装任何npm包时，我每次都得到相同的错误。

尝试删除并设置代理，但不起作用。

其中一个原因是关于您的IP地址设置。如果是ubuntu，请检查ip addr、ping和netplan。

在我的示例中，我设置了一个ubuntu (18.04) VM的静态IP，但我忘记了DNS。然后我得到了和你完全一样的错误。

我通过更改文件/etc/netplan/50-cloud-init.yaml来解决这个问题，如下所示：

# This file is generated from information provided by
# the datasource.  Changes to it will not persist across an instance.
# To disable cloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
    ethernets:
         ens33:
                 addresses: [192.168.233.132/24]
                 dhcp4: no
                 gateway4: 192.168.233.2
                 optional: true
                 nameservers:
                         addresses: [223.5.5.5, 8.8.8.8]
