During a similar issue I encountered with an Angular project, I found that small, undetectable formatting errors in the JSON configuration could cause npm install to fail. I traced the problem back to an extra character that snuck in when copying over configuration files. In my case, re-typing the affected line in a dedicated text editor clarified the issue. Sometimes, simply verifying each line with a JSON linting tool can help pinpoint the exact location of the issue. Paying close attention to whitespace and quote consistency resolved the error in my project.
