How to change LinuxFxVersion in Azure function app - azure

Question

i have azure function with LinuxFxVersion set to DOTNET:
"siteProperties": {
"metadata": null,
"properties": [
{
"name": "LinuxFxVersion",
"value": "DOTNET|3.1"
},
{
"name": "WindowsFxVersion",
"value": null
}
],
"appSettings": null
},
I want to set it to Python:
"siteProperties": {
"metadata": null,
"properties": [
{
"name": "LinuxFxVersion",
"value": "Python|3.9"
},
{
"name": "WindowsFxVersion",
"value": null
}
],
"appSettings": null
},
According to msdn source, I need to use Power shell to change it:
az functionapp config set --name <func_name> --resource-group <rg> --linux-fx-version 'Python|3.9'
but im getting error:
'3.9' is not recognized as an internal or external command,
operable program or batch file.
When im typing just 'Python' i get response:
Operation returned an invalid status 'Bad Request'
How to change linux fx version in Azure Function from .NET to Python?

Answer 1

The way you can solve this error in Powershell is to wrap up the string containing the pipe character with quotes.
Here are multiple examples:
az functionapp config set --name <func_name> --resource-group <rg> --linux-fx-version '"Python|3.9"'
az functionapp config set --name <func_name> --resource-group <rg> --linux-fx-version 'Python"|"3.9'
If you are running the above command in bash use : instead of |
az functionapp config set --name <func_name> --resource-group <rg> --linux-fx-version "Python:3.9"
