根因分析

回溯解析器超过其搜索深度，因为两个或多个软件包需要共享依赖项的互斥版本，形成不可满足的约束图。

English

The backtracking resolver exceeded its search depth because two or more packages require mutually exclusive versions of a shared dependency, creating an unsatisfiable constraint graph.

解决方案

  1. 85% 成功率 
    # Inspect the conflict
pip install --dry-run foo==1.0 bar==2.0
# Relax pins to compatible ranges
pip install 'foo>=1.0,<2' 'bar>=2.0,<3'
  2. 80% 成功率 
    pip install uv
uv pip install foo==1.0 bar==2.0

无效尝试

常见但无效的做法:

  1. 85% 失败

    The constraint set is unsatisfiable; more rounds just burns CPU before failing again.

  2. 70% 失败

    Skips dependency installation, leaving imports broken at runtime.
