构建onnx时“'.../src/onnx/gen_proto.py'不是Conan命令”

问题描述 投票：0回答：1

我的项目中有以下 

conanfile.py
，我在其上运行命令 
conan install . --output-folder=build --build=missing -v
。

import os

from conan import ConanFile

class ProjectRecipe(ConanFile):
    settings = "os", "compiler", "build_type", "arch"
    generators = "CMakeToolchain", "CMakeDeps"

    def requirements(self):
        self.requires("armadillo/12.6.4")
        self.requires("openssl/3.3.1")
        self.requires("onnxruntime/1.18.1")
        self.requires("boost/1.86.0", force=True)

命令成功完成。以下是输出的后半部分：

可能出了什么问题？预先感谢您的帮助。

编辑：以下是导致错误的 ninja 文件的规则。

根本原因是 onnx 的柯南配方将 

PYTHON_EXECUTABLE
变量设置为 
sys.executable
。通常这是用于调用 Conan 的 Python 程序，但在您的情况下它是 conan.exe。

这在上游被报告为 issue #22636 和 #21790。

快速而肮脏的解决方案是修补onnx的conanfile.py，如此评论中所述：

使用第 

tc.variables["PYTHON_EXECUTABLE"] = "python"
行修改 conanfile.py 后，它现在可以工作了。

当然，您需要安装独立的 Python 才能正常工作。
