Hello,
is it possible to install Python wheel packages from an internal PyPI repository in Anaconda Code? I keep getting this error, when adding the URL to the *.whl file:
An error occurred when loading package dependencies. Please try a different installation method, version, or package.
The package has no dependencies on other packages. I can install and use the Wheel locally via PyPI without any issues. Do I need to transform the package to the Conda package format and host it via Anaconda Server?
Thank you
Loading a Python wheel from a URL should work fine with the standard wheel format.
Is it a pure Python wheel? Anaconda Code runs with pyodide, so it can only load pure Python wheels or wheels compiled for wasm32.
Yes it’s a pure python wheel.
I’ve tried the following:
- installing via pip and using the package locally
- moved the package to a public accessible web server
- make sure CORS headers are correctly set
- to load and use it via pyodide
Still I get “Unable to load package: …” in Anaconda Code when trying to add the package.
Loading a custom wheel is done via micropip.install() under the hood.
Are all of its dependencies pure Python wheels and/or available in the pre-built pyodide packages?
Thank you very much for your efforts.
Yes all it’s dependencies are pure Python wheels. I only import “phonenumbers” from PyPi. This is my test script for Pyodide.

Open your browser console to see Pyodide output
<script type="text/javascript">
async function main(){
let pyodide = await loadPyodide();
await pyodide.loadPackage("micropip");
const micropip = pyodide.pyimport("micropip");
await micropip.install('phonenumbers');
await pyodide.loadPackage('https://.../pulp/content/mplus/phonenumberparser-0.1.4-py3-none-any.whl')
await micropip.install('phonenumberparser')
console.log(pyodide.runPython(`
from phonenumberparser import PhoneNumberParser
parser = PhoneNumberParser()
print(parser.parse_phone_number("+41176123456789", "", 7, "DE"))
`));
}
main();
</script>
</body>
</html>
Output is, as expected:
Loading micropip, packaging
pyodide.asm.js:10 Loaded micropip, packaging
pyodide.asm.js:10 Loading phonenumberparser
pyodide.asm.js:10 Loaded phonenumberparser
pyodide.asm.js:10 0176123456789
Are you able to view the debug console for the add-in? Click on the left-arrow icon in the upper-right corner, then choose Attach Debugger (this is for Windows Desktop version of Excel). It will bring up the browser devtools and hopefully show more of the underlying error.

Thank you for pointing me in the right direction. I was able to figure out that it was a CORS header problem. It looks like packages are cached for a while, since I was unable to see changes to the header directly.
