Executing npm install on Windows 10 (Node 0.10.40, npm 2.0.0) produces an error: missing ‘appConfig.json’. Should I create this file manually?
C:\dev\proj> npm install
npm info: Running with npm 2.0.0 and Node 0.10.40.
npm err: ENOENT, 'C:\dev\proj\appConfig.json' not found.
In a similar situation, I encountered an error due to a missing configuration file referenced in some build scripts. My first step was to review project documentation to see if there was a standard configuration sample provided. In my case, the missing file was indeed expected to be present and should be created manually with default settings. Upgrading Node and npm versions may help in some cases, but verifying your build process and configuration requirements worked best for me. Sometimes regenerating the project with modern tools resolves these discrepancies.
