In fact, I can't type any other arguments after the All, it is automatically running.

Unfortunately I don't have an access to M101J but based on the tests on M202, M102, M101P, M101JS I can't reproduce the issue you're seeing.

Is the course still available? What version of py are you using?

[checkcheckzz]

Hi:

I am currently taking this course, it just started a week ago. My python version is 2.7.

[przemyslawpluta]

Just signed in for M101J and still can't replicate the issue. Can download all videos on win7 without any errors with py 2.7.

Try npm uninstall mongo-edu -g then npm cache clean and npm install mongo-edu -g. Is it home or work network?

[checkcheckzz]

I did not try your solution yet. Some error occurs in my npm, it happens a lot error. Anyway, I will try it after I fix the npm error.

[przemyslawpluta]

Have you fixed your npm setup?

[checkcheckzz]

unfortunately, not... I posted issues in npm repo, got reply, tried several solutions, failed. I am quite busy these days. Thus, I don't have time to explore it further.
But I think mongo-edu will work in the end. I definitely need to download the videos.

[przemyslawpluta]

Was thinking about publishing experimental package where you don't have to install nodejs or npm based on jxcore. If you're interested just let me know which OS are you on and I can publish something for you.

[checkcheckzz]

I use Windows7. Thanks!.

[przemyslawpluta]

32bit or 64bit?

[checkcheckzz]

64 bit

[checkcheckzz]

But npm finally works. but the error occurs again as I listed in my first post...

C:\Users\niuzhist>mongo-edu -d --cw /videos/

BTW it looks like you're passing your args in the incorrect way ... It should be mongo-edu -d /videos/ --cw not mongo-edu -d --cw /videos/ unless you want the download path to be created in ~ ./true

Change the args order and if it still crashes just add --verbose and post the output before the crash.

[checkcheckzz]

I still got errors...And I use the youtube-dl, a python package to download the video. But I have to download them one by one.

[przemyslawpluta]

Can you post the output you get with --verbose.

[przemyslawpluta]

Try to reinstall py.

[przemyslawpluta]

Closing the case will reopen if updates provided.
