Hanging on 'Downloading library build "*" (might take a while)'

[arvoelke]

On the current master branch of mbed-cli:

mbed new simple_test --mbedlib 
[mbed] Working path "/home/arvoelke/git/..." (program)
[mbed] Creating new program "simple_test" (git)
[mbed] Adding library "mbed" from "https://mbed.org/users/mbed_official/code/mbed/builds" at branch/tag "tip"
[mbed] Downloading library build "65be27845400" (might take a while)

I've tried this three times now, each time keeping it open for more than 24 hours -- and it still hangs.

If I visit the above url (https://mbed.org/users/mbed_official/code/mbed/builds) and click on the first build (65be27845400), it takes me to an invalid page:

https://os.mbed.com/users/mbed_official/code/mbed//builds/65be27845400/

An error occurred while processing your request no such method: builds

Note there are two slashes (//) in the URL. If I remove one of the slashes then the link becomes valid. Is there a fix or work-around? Thanks.

Did some checking around: https://github.com/ARMmbed/mbed-cli/blob/c2528f6fca8d73be0f5cb5e494dd4987f40c39fa/mbed/mbed.py#L393-L400 and noticed that the empty string check is an infinite loop in Python3 (since b'' != ''). Fixed in #969.

For everyone still encountering this issue after 2022:

pip uninstall mbed-cli
git clone https://github.com/ARMmbed/mbed-cli.git
cd mbed-cli
pip install --editable .

edit mbed/mbed.py and change line 397 to:

while data != b'':

and line 294 to:

return stdout.decode("ANSI")

then you should be able to download the libraries

return stdout.decode("ANSI")

led to this error on my machine (Ubuntu 22.04):

ERROR: Unknown Error: unknown encoding: ANSI

so I changed it back to the original, then it worked successfully.

This worked but without editing line 294 on Ubuntu (editing the line gave another error when creating the project). Thanks a lot, I have been going crazy over this
