micropip.install(..., deps=False) leads to runtime error

[m-albert]

First of all thanks for this amazing project!

I wanted to quickly leave this report here. In a fresh https://jupyter.org/try-jupyter/lab/index.html, the following

import micropip
await micropip.install('dask-image', deps=False)

leads to

File /lib/python3.12/site-packages/micropip/wheelinfo.py:126, in WheelInfo.install(self, target)
    115 """
    116 Install the wheel to the target directory.
    117 
   (...)
    123     4. The wheel's metadata is set.
    124 """
    125 if not self._data:
--> 126     raise RuntimeError(
    127         "Micropip internal error: attempted to install wheel before downloading it?"
    128     )
    129 _validate_sha256_checksum(self._data, self.sha256)
    130 self._extract(target)

RuntimeError: Micropip internal error: attempted to install wheel before downloading it?

Same happens when trying to install other packages. Some months ago this was still working.

Hi @m-albert! This is the same issue as #157 and #180, and has been fixed with #187, which was a part of the 0.9.0 release. Thank you for reporting!

A full fix will be available with Pyodide 0.28 (hopefully by the end of April), where this PR will be included: pyodide/pyodide#5461
