Versions of pyo3 conflict when building with pyo3 0.22.0 #66

Closed cardigan1008 closed 3 months ago

cardigan1008 commented 3 months ago

In my project, I include pyo3 0.22.0 like this:

pyo3 = { version = "0.22.0", features = [
    "extension-module",
    "multiple-pymethods",
], optional = true }

I also include pyo3-stub-gen and pyo3-stub-gen-derive 0.6.0 like this:

pyo3-stub-gen = "0.6.0"
pyo3-stub-gen-derive = "0.6.0"

When I run cargo build, it turns out that the building process terminated because of version conflicts:

error: failed to select a version for pyo3.
    ... required by package numpy v0.21.0
    ... which satisfies dependency numpy = ">=0.21.0" of package pyo3-stub-gen v0.6.0
    ... which satisfies dependency pyo3-stub-gen = "^0.6.0" of package hifitime v4.0.0-alpha.1 (/path/to/myproject)
versions that meet the requirements ^0.21.0 are: 0.21.2, 0.21.1, 0.21.0

the package pyo3 links to the native library python, but it conflicts with a previous package which links to python as well:
package pyo3 v0.22.0
    ... which satisfies dependency pyo3 = "^0.22.0" of package myproject v4.0.0-alpha.1 (/path/to/myproject)
Only one package in the dependency graph may specify the same links value. This helps ensure that only one copy of a native library is linked in the final binary. Try to adjust your dependencies so that only one package uses the links = "python" value. For more information, see https://doc.rust-lang.org
/cargo/reference/resolver.html#links.

My project relies on pyo3 0.22.0 and I tried to change the version to 0.21.2 etc. as the error mentioned. However, some features are missing. So is there any solution to deal with this conflict?

This looks caused by numpy crate, which does not support PyO3 0.22 yet. It is required from pyo3-stub-gen with numpy feature which is enabled by default. Please try following:

pyo3-stub-gen = { version = "0.6.0", default-features = false }

Thanks for your prompt response. It works :)
