Adding NPM packages via the 'Libraries' tab fails with error

[Banbury]

Describe the bug Adding a library via the 'Libraries' tab or manually in package.json (and then pressing 'Synchronize'), fails with the following error message:

12/11/2021 08:36:05.921 [Studio] HTTP Syncing libraries...
12/11/2021 08:36:06.284 [Studio] HTTP Command executed successfully: internal/modules/cjs/loader.js:967
     throw err;
     ^

   Error: Cannot find module 'npmlog'

     ]
                             }

To Reproduce Steps to reproduce the behavior:

1. Open the 'Library' tab.
2. Press the add button
3. Select 'Type a custom command'
4. enter 'install underscore'
5. Press 'Execute' (BTW 'Search library on NPM (recommended)' is missing the 'Execute' button)
6. A message 'Command execution completed' pops up.
7. The library is not added and package.json is not updated.
8. In the console window the error message is displayed.

Expected behavior The package is installed and displayed in the 'Libraries' tab. The dependencies in the file package.json are updated.

Environment (please complete the following information):

• OS: Windows
• Browser Firefox
• Browser Version 95.0
• Botpress Version 12.26.8 - Build 20211202-1851_BIN
• NodeJS Builtin

hello , I have same issue but I found solution u can work with until they fix the issue

inside Botpress file go to library directory

cd ./data/bots/{{your-bot-name}}/libraries

install npmlog

npm i npmlog

this will fix the issue , if it not showing after the installing lib , just restart Botpress.
