Compose: [24498] Failed to execute script docker-compose

[thomasfaller]

Description of the issue

I'm new to Docker and playing around with Dockerfiles and .yml scripts. I tried to replicate the example on the get started page for compose and when I type either docker-compose up or docker-compose build I get the same error message as follows:

Traceback (most recent call last):

def get_hit_count():
    retries = 5
    while True:
        try:
            return cache.incr('hits')
        except redis.exceptions.ConnectionError as exc:
            if retries == 0:
                raise exc
            retries -= 1
            time.sleep(0.5)


@app.route('/')
def hello():
    count = get_hit_count()
    return 'Hello World! I have been seen {} times.\n'.format(count)

if __name__ == "__main__":

Additional information

Since I'm new to Docker, I'm not too sure where to look for a more extended log for this.
Any help will be greatly appreciated!

OS version / distribution, docker-compose install method, etc.

Mac OS: 10.14

Looks like a bug in the requests Python library. Can you share the full output of the docker-compose version command? Does disabling your proxy get rid of the issue?

This report indicates this is in fact a bug in Python.

As a workaround, you may want to try tweaking your proxy configuration.

[ijc]

Closing since this appears to be (/have been) a Python issue.

what should be done to resolve this??

How to resolve this??

[hal90210]

Go to your Network settings > click on the Advanced button > click on the Proxies tab.

Remove any addresses in the Bypass proxy settings for these hosts & Domains. Click Ok/Apply

try your command again.

Adding this here as I experienced a similar issue that had a very different reason.
Context: I executed a docker-compose command from the new Windows Terminal that then needed to fetch a docker image from an authenticated registry. As I was not logged in, docker-compose wanted to write that error about my expired Auth token to console and instead showed this:

Traceback (most recent call last): File "logging\__init__.py", line 879, in emit File "site-packages\colorama\ansitowin32.py", line 41, in write File "site-packages\colorama\ansitowin32.py", line 162, in write File "site-packages\colorama\ansitowin32.py", line 190, in write_and_convert File "site-packages\colorama\ansitowin32.py", line 195, in write_plain_text LookupError: unknown encoding: cp65001 Logged from file service.py, line 1240 Traceback (most recent call last): File "logging\__init__.py", line 879, in emit File "site-packages\colorama\ansitowin32.py", line 41, in write File "site-packages\colorama\ansitowin32.py", line 162, in write File "site-packages\colorama\ansitowin32.py", line 187, in write_and_convert File "site-packages\colorama\ansitowin32.py", line 195, in write_plain_text LookupError: unknown encoding: cp65001 Logged from file main.py, line 1082 Traceback (most recent call last): File "docker-compose", line 6, in <module> File "compose\cli\main.py", line 72, in main File "compose\cli\main.py", line 128, in perform_command File "compose\cli\main.py", line 1084, in up File "compose\cli\utils.py", line 36, in yesno File "compose\cli\utils.py", line 53, in input File "site-packages\colorama\ansitowin32.py", line 41, in write File "site-packages\colorama\ansitowin32.py", line 162, in write File "site-packages\colorama\ansitowin32.py", line 190, in write_and_convert File "site-packages\colorama\ansitowin32.py", line 195, in write_plain_text LookupError: unknown encoding: cp65001 [15608] Failed to execute script docker-compose

After logging in to the registry (aws ecr in my case) things worked as expected

No idea why this worked, but it did.
