I have a static site on App Platform that I cannot get to build correctly.
I am using Jinja to generate a static site from some templates. I have a script called
build.py in the root directory of the app that does this. It works locally with
python 3.8.5, so I know it’s not an issue with the script itself, but maybe the environment. I’ve also gotten the App to run just fine with just the pre-built html made by running the build script locally instead of as a part of the deployment process.
The initial section of the deployment always runs as follows:
=> Initializing build => Retrieving source code to /workspace => Selecting branch "main" => Checking out commit "[a commit hash]" => Validating environment => Building app using buildpacks => Configuring custom build command to be run at the end of the build: [see below after this section] => Running buildpack detection digitalocean/python-appdetect 0.0.2 heroku/python 0.188.4 digitalocean/procfile 0.0.3 digitalocean/custom 0.1.0 => Building app -----> Installing python-3.8.7 -----> Installing pip 20.1.1, setuptools 47.1.1 and wheel 0.34.2 -----> Installing SQLite3 rm: cannot remove '/workspace/.heroku/python/apt/state/lists': Directory not empty Sqlite3 failed to install. -----> Installing requirements with pip Collecting Jinja2==2.11.3 Downloading Jinja2-2.11.3-py2.py3-none-any.whl (125 kB) Collecting MarkupSafe==1.1.1 Downloading MarkupSafe-1.1.1-cp38-cp38-manylinux2010_x86_64.whl (32 kB) Installing collected packages: MarkupSafe, Jinja2 Successfully installed Jinja2-2.11.3 MarkupSafe-1.1.1
What comes next fails a few different ways:
When I use
python build.py as the build command, it fails with
ImportError: No module named site. Running
python -V as the build command shows that the command invokes version
python3 build.py as the build command instead fails with
Fatal Python error: Py_Initialize: Unable to get the locale encoding ModuleNotFoundError: No module named 'encodings'
python3 -V as the build command shows it invoking version
bash: python3.8: command not found
From the logs it looks like python3.8 is installed as a part of building the app, but I can’t seem to invoke it.
Is it possible to run a python script with
python3.8 as a part of the build step for a static site on App platform, and if so, how can I invoke it correctly here? Not even sure this would fix the issue, but it certainly isn’t working with python 2.6
