Docker invalid reference format error when installing laravel sail - laravel

I am trying to install a new Laravel project using the code provided in the official Laravel documentation
curl -s "https://laravel.build/example-app" | bash
However, I keep receiving this error:
docker: invalid reference format.
See 'docker run --help'.
bash: line 16: cd: example-app: No such file or directory
I have tried both resetting my Docker application to default factory settings and uninstalling and reinstalling it, but the error keeps reappearing. What makes it even weirder, roughly a month ago I was doing the same thing when first experimenting with Laravel and Docker and everything was working fine. Does anybody know what could be the case?

if you are working with Windows Subsystem Linux (WSL), try executing bash, because it seems like your device doesnt recognize the docker container.
if that doesnt work, check if php, composer and docker are installed correctly, and if you have downloaded and configured a distro such as Ubuntu.
If the issue still is not fixed, execute wsl --setdefault -(NAMEOFDISTRO) in the terminal.
I ran into this same issue a couple of weeks ago and fixed it by using combinations of the solutions above.
I hope this helped!

Trying to set up PSQL and i get this error :

I am trying to start a Spring project using a PSQL database.
I have installed PSQL using Homebrew but,
When i run :
brew services start postgresql
I get this error:
Error: Failure while executing; /bin/launchctl bootstrap gui/501 /Users/[myusername]/Library/LaunchAgents/homebrew.mxcl.postgresql.plist exited with 5.
I am following this tutorial:
https://medium.com/#viviennediegoencarnacion/getting-started-with-postgresql-on-mac-e6a5f48ee399
Using a mac which is up to date.
Any help is greatly appreciated!
So my postgres service was started apparently.
Therefore when i was trying to start it again it causes an error.
Fix was to stop it and re run.
This error is due to the fact the server is already running. We need to stop and start it.
For Mac Users:
brew services stop postgresql
brew services start postgresql
EDIT: This may be a track, but it doesn't happen for me again since I updated to Monterey and running PSQL13
A full computer restart did solve it for me.
PS: I think the problem is related to the checkbox on log off "Reopen windows when logging back in".

docker-compose command not available for mac

I installed docker with the instructions here, downloading from docker-hub
https://docs.docker.com/docker-for-mac/install/
But when I run docker-compose I get this error
pyenv: docker-compose: command not found
The `docker-compose' command exists in these Python versions:
3.6.5/envs/myenv
Also, docker-compose is available under /Users
which docker-compose
/Users/<username>/.pyenv/shims/docker-compose
In this link says, docker-compose for mac need not be installed explicitly as it is part of docker for desktop mac.
https://docs.docker.com/compose/install/
Is something wrong with my installation?
I ran into the same issue on macOS today. Turned out that you need to run the installed app once, it does some additional downloading and setup. That setup includes setting up your path variables.
docker-compose is a utility that is now a parameter in mac docker
so instead of docker-compose up, its now docker compose up
if you install docker from official website then docker-compose will come along with that for mac so need to either upgrade and documentation is present there.

MJML run and watch error

I'm following the tutorial on https://mjml.io/documentation/#basic-layout-example
And followed these instructions to install https://mjml.io/download
But whenever I want to use ./node_modules/.bin/mjml index.mjml or mjml index.mjml I get the following error:
Command 'sed' is available in '/bin/sed'
The command could not be located because '/bin' is not included in the
PATH environment variable.
sed: command not found
/usr/bin/env: 'node': No such file or directory
I have no idea what I'm doing wrong and Google hasn't been helpful so far.
Any idea why this is happening? Thanks for your time :(
Seems you have messed your PATH environment variable. The sed program is there as is part of the core packages. You can try to do something like the mentioned here.
Also try to reach the mjml support group in slack
I think you have not installed node properly. Try reinstalling it.
If you reinstalled the node and then also you are facing the problem then there is some problem with Windows because a few days ago I was facing a problem when I was running the npm run build command then I switch to my Virtual box Linux OS there it works fabulously.

How to run a library in docker - confusion

I am trying to use microsoft's cntk library on a mac; for this purpose I am using Docker. I am not an expert in all this, though, so I am having a hard time figuring out how to make it work.
From my understanding, Docker provides a way to run an app in a virtualized environment, without having to virtualize the entire operating system. So you download (or create) images, and you run them in "containers".
Alright, so I have followed the required steps to make the cntk library work on Docker; and if I list the images, I find
$: docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
microsoft/cntk latest c2c192036e19 7 days ago 5.92 GB
ubuntu 14.04 7c09e61e9035 5 weeks ago 188 MB
hello-world latest 48b5124b2768 2 months ago 1.84 kB
At this point I want to run of the tutorials that are in the cntk repository. I have downloaded the master branch of the cntk repository on my desktop and try to run one of the examples in the "Tutorial" folder, but I get the following error:
terminal~ username$ docker run -w /Users/username/Desktop/CNTK-master/Tutorials microsoft/cntk configFile=lr_bs.cntk
container_linux.go:247: starting container process caused "exec: \"configFile=lr_bs.cntk\": executable file not found in $PATH"
docker: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"configFile=lr_bs.cntk\": executable file not found in $PATH".
ERRO[0001] error getting events from daemon: net/http: request canceled
terminal~ username$
Essentially I call docker run with the -w flag to inform him of where the files are, but it does not work. I tried searching online but it's not clear to me how to solve the issue. Should I create a new image? Should I call the docker run command with different parameters?
The -w flag sets the working directory, which is just the default directory inside the container. Your directory is on the host, so it won't work here. Instead you need to use volumes to mount your directory on the host into the container. The final paragraph in the document you link has an example:
$ docker run --name cntk_container1 -ti -v /project1/data:/data -v /project1/config:/config cntk bash

installing appflower on xampp for linux

I've been trying to figure out this problem for a while now and I thought I'd ask it here on stackexchange in case somebody out there has tried this and successfully got it to work.
I'm trying to install a RAD webapp tool called AppFlower through Xampp for Linux.
I am also experiencing issues with the command below:
symfony afs:init
symfony: command not found
This is the final command used to start up the AppFlower Studio dev environment, but this command doesn't work.
I have tried using:
./symfony afs:init
Same error as above
php ./symfony afs:init
gives a php error saying it isn't installed, but this is Xampp for Linux, so that command won't apply
/opt/lampp/etc/php.ini ./symfony afs:init
it will give a permission denied error, but even with 'sudo' in front, it says 'command not found'
The solution posted on the appflower forum is for xampp itself, but the problem I have is that they use the php.exe command to run the 'symfony afs:init' command, which xampp for linux doesn't have. The closest thing I could think of was to use the php.ini file, but (as seen above) that doesn't work.
Hopefully somebody can assist regarding this issue.
Regards,
Note. The process to run appflower on a manual version of lamp (one in which php, mysql, apache are all downloaded separately) is a lot more complex and the xampp installation is supposed to be much easier (in fact it is) but at the last point of this installation, this 'symfony afs:init' command is the only problem.
If you are already using Linux, why not install AppFlower directly. It's pretty straightforward, maybe i lost something on the way, understanding why you use XAMMP for Linux.
