    }

假设这些依赖项将由 npm 解决。但是，我在没有 Internet 连接的情况下安装这些软件包。因此，错误提示如

Downloading package 'OmniSharp for Linux (x64)'     retrying from 'https://roslynomnisharp.blob.core.windows.net/releases/1.37.6/omnisharp-linux-x64-1.37.6.zip' Failed at stage: downloadPackage
Error: getaddrinfo ENOTFOUND download.visualstudio.microsoft.com

无论如何我可以预先下载zip并将其放在某个地方以便可以跳过下载部分吗？如果是，这个位置在哪里？

提前致谢。
