Hey @nsharon,
I apologize for the late reply. The Zowe Editor has seen lots of bug fixes & improvements throughout the year, so I would attempt to do this again with the current version (or ‘staging’ branch if you would like the latest and greatest). If it still doesn’t want to npm install, can you specify your node version, your OS (guessing Windows because of C:\Users\neena.b\AppData|) & that full debug log located in that specified temp location
