python : request dependency idna failed "ImportError: No module named idna"

Question

I am using the request module in python, which has inda as a dependency.

I am keeping idna module inside request module but still it is not able to detect the inda module.

"/mnt/yarn/usercache/root/appcache/application_1522067995292_0020/container_1522067995292_0020_01_000001/slackclient.zip/slackclient/requests/packages.py", line 7, in ImportError: No module named idna

correct i am installing using pip only. one quick thing i would like to mention here it is working in my local python but when i am uploading the python dependency to aws glue then it is breaking. — Yashwant Chandrakar, Mar 26 '18 at 16:41
Then you don't have `idna` in your requirements file for aws. — user3483203, Mar 26 '18 at 16:44
idna module is there inside requirement module on the basis of that only i am testing it. — Yashwant Chandrakar, Mar 26 '18 at 16:52

Unfortunately, `pip` isn't starting because of this very error for me (OpenSUSE 15.3). – Artem Russakovskii Sep 19 '22 at 17:25

Use requirements.txt avoid these dependency mix-ups.

Firstly, when your code is working all good, do this

$ pip freeze > requirements.txt

This stores all the installed packages into the text file.

Now use requirements.txt file to install all modules wherever it runs hereafter

$ pip install -r requirements.txt

If needed, can upgrade your modules and check everything working cool and then update requirements.txt again.

When not mentioning the versions, usually the latest versions of the packages are fetched and installed. Some of the updates from dependency's dependency(inception) package might break.

This information would only help if the program is already running properly and doesn't solve the problem of the dependency issue. — AlphaCR, Feb 03 '20 at 03:43
