Error Deployment on Azure

Question

Could you please help me with the following error? I am trying to deploy a web app to Azure and I encounter the following issue:

Even if by requirements, a newer version of setuptools is installed, the deployment fails with the error:" RuntimeError: cryptography requires setuptools 18.5 or newer, please upgrade to a newer version of setuptools".

The whole log is as it follows:

Command: "D:\\home\\site\\deployments\\tools\\deploy.cmd" Handling python deployment. Detected requirements.txt. You can skip Python specific steps with a .skipPythonDeployment file.

Answer 1

You need to upgrade the python module setuptools installed on your target.

If you used python3 (it looks to be case from the log), run this command: pip3 install --upgrade setuptools

If you are still using python2 then this command pip install --upgrade setuptools .

If you do not have permission access then use the flag --user : pip3 install --user --upgrade setuptools

Adding to OlivierM, installing Python packages in Azure App Services is little tricky using pip. It's recommended to use wheels for installing Python dependencies.

Some packages may not install using pip when run on Azure. It may simply be that the package is not available on the Python Package Index. It could be that a compiler is required (a compiler is not available on the machine running the web app in Azure App Service).
