根因分析

目标平台/Python 组合没有预构建 wheel，pip 回退到从源码构建，而本地工具链（gcc/clang）不支持所需标志或缺少头文件。

English

No prebuilt wheel exists for the target platform/Python combo, so pip falls back to building from source, and the local toolchain (gcc/clang) does not support the required flags or lacks headers.

解决方案

  1. 85% 成功率 
    Install build deps: apt-get install -y build-essential python3-dev (or xcode-select --install on macOS)
  2. 80% 成功率 
    Upgrade the compiler: on macOS 'brew install gcc' and set CC=gcc-13; on Linux use a newer distro or toolchain
  3. 75% 成功率 
    Use a prebuilt manylinux wheel from a different index: pip install --only-binary=:all: --extra-index-url https://download.pytorch.org/whl/cpu somepkg

无效尝试

常见但无效的做法:

  1. 90% 失败

    Forces source builds for everything, making the failure more likely and slower.

  2. 85% 失败

    Disables isolation but the compiler still lacks the required flags/headers.

  3. 95% 失败

    The build failure is deterministic; retries produce the same compiler error.
