I am trying to buiil Dart-VM on windows, I follow the steps as described here
https://github.com/dart-lang/sdk/wiki/Building
When I run the build.py command as below:
.\tools\build.py --mode release --arch x64 create_sdk
I get the following error:
gn gen --check in out\ReleaseX64
Traceback (most recent call last):
File "D:\ops\dart\sdk\tools\gn.py", line 436, in <module>
sys.exit(main(sys.argv))
File "D:\ops\dart\sdk\tools\gn.py", line 423, in main

Tried to run GN, but it failed. Try running it manually:

return 'use_goma = true' in open(args_gn, 'r').read()
IOError: [Errno 2] No such file or directory: 'out\\ReleaseX64\\args.gn'
It seems missing the args.gn file in out\ReleaseX64 folder. but I cannot find args.gn in Dart source folders. Is it generated during building process? whether I do wrong steps led to no such file generated?

I have been trying to use a custom dockerfile for mounting dags and plugins as follows:
FROM apache/airflow:2.3.0-python3.7
COPY ./dags/ /opt/airflow/dags/
COPY ./plugins/ /opt/airflow/plugins/docker push
COPY requirements.txt .
RUN pip install -r requirements.txt
EXPOSE 5555
which I am building as:
docker build -f base.dockerfile --pull --tag lqc-airflow:0.0.1 .
minikube image load lqc-airflow:0.0.1
and then doing a helm install
helm upgrade $RELEASE_NAME apache-airflow/airflow --namespace $NAMESPACE --set images.airflow.repository=lqc-airflow --set images.airflow.tag=0.0.1
which however is making just the airflow-worker-0 pod fail due to the following error:
The above exception was the direct cause of the following exception:

I am just following the reading advisory from airflow: https://airflow.apache.org/docs/helm-chart/stable/manage-dags-files.html
please note that there are no such name resolution errors if I dont use my custom docker file. Kindly help!
thanks #Hussein also for your support, but I could solve it by myself. I saw that the logs of the airflow-migrations pods, complaint of a revision id not being found. So somehow I chanced upon: https://airflow.apache.org/docs/apache-airflow/stable/migrations-ref.html
and there I saw the airflow tag which was above/carrying that alembic revision.
My revision id was ecb43d2a1842 and thus the changes to my docker file were:
FROM apache/airflow:2.4.3
COPY ./dags/ /opt/airflow/dags/
COPY ./plugins/ /opt/airflow/plugins/
COPY requirements.txt .
RUN pip install -r requirements.txt
thus 2.4.3 was the catch.
I'm new to docker and I'm trying to follow this simple "getting started" tutorial https://docs.docker.com/compose/gettingstarted/ using a newly first time installation of docker (for Windows 10) dowloaded from here: https://hub.docker.com/editions/community/docker-ce-desktop-windows/.
At step 4 of this tutorial i get this error:

EDIT: The accepted solution in docker-compose unable to start, unfortunately, did not work.
What is going wrong?
I have the same issue...
Try:
$nano ~/.docker/config.json
In this file change credsStore to credStore
Now run your docker-compose. If its not works try sudo
try to add to the environment path :
C:\Program Files\Docker\Docker\resources\bin
If you are using WSL2 run this command
sudo ln -s /mnt/c/Program\ Files/Docker/Docker/resources/bin/docker-credential-desktop.exe /usr/bin/docker-credential-desktop.exe

python 2.7
py2app version = most recent as of Feb 11th 2019
I follow the official instructions found here:
https://py2app.readthedocs.io/en/latest/tutorial.html
I'm trying to get it to make a standalone for a 'hello world' program.
Everything works until the last step, which is 'python setup.py py2app'. I get the following error:
"Traceback (most recent call last):
File "setup.py", line 18, in
setup_requires=['py2app'],"
I did not modify the contents of the setup.py file, so they are as follows"
#
from setuptools import setup
APP = ['appp.py']
DATA_FILES = []
OPTIONS = {}
setup(
app=APP,
data_files=DATA_FILES,
options={'py2app': OPTIONS},
setup_requires=['py2app'],
)
#
Note that prior to this last step, I did indeed run 'rm -rf build dist' as instructed.
The error that I get is:

I am getting this error Please let me know how to resolve . . .
This error happens because cmake is either (a) not installed or (b) not on the user's path.
In this case, the OP had downloaded the cmake gui application from cmake.org, and copied it to /Applications. This app doesn't add the path to the binaries automatically, which is why the script couldn't find cmake.
By adding the path to the cmake binaries (bash syntax):
PATH=$PATH:/Applications/CMake.app/Contents/bin
the OP was able to successfully build opencv.
Most package managers - e.g. homebrew or macports whould have automatically added a path to the user's profile that would have permitted it to run without having to modify the path any more.
You may need to install CMake
My-Mac: opencv$ brew install cmake
