Error with PyInstaller during deployment of Azure function

[dchouren]

Platform/OS: Linux Ubuntu
Regression From: Was working ~2 weeks ago

Bug description
I am developing an Azure function (Python) through VSCode. When I run 'func azure functionapp publish RootCauseAnalyzer --build-native-deps', I get a very long trace due to requirements.txt installing, culminating with this error:

  Installing build dependencies ... done
  Getting requirements to build wheel ... error

You are using pip version 19.0, however version 19.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

My Dockerfile, if it's relevant:

FROM python:alpine

# If you prefer miniconda:
#FROM continuumio/miniconda3

LABEL Name=rca_vscode Version=0.0.1
EXPOSE 3000

WORKDIR /app
ADD . /app

# Using pip:
RUN python3 -m pip install -r requirements.txt
RUN pip install -U nltk
CMD ["python3", "-m", "rca_vscode"]

When I add the --no-bundler option I get:

Do you know what is happening with Pyinstaller? This same deployment flow was working about two weeks ago.

When I try to deploy straight from VSCode (UI, right click > 'Deploy to Function App') I get

> Executing task: . .env/bin/activate && func pack <

source activate root_cause_analyzer
pip download -r /Users/.../requirements.txt --dest /var/folders/xl/gfzrh7wx7wbdvpltpzq80dm40000gn/T/azureworker5mnd54r6

I have the same issue, can't redeploy, get:

[dmitrysmirnovfinnair]

Oho, but adding this flag helped: --no-bundler, as per suggestion here: #1092

[dchouren]

Closing. --no-bundler does indeed work for fixing any PyInstaller complications. I also had to update rolled key somewhere that was preventing auth and that was confusing me.

[karllhughes]

--no-bundler is deprecated.

Should we use --no-build for Python projects now?

If anyone else run into this problem, try updating azure-functions-core-tools and/or azure-cli
