根因分析

使用 `--no-build-isolation` 要求构建后端（setuptools、wheel 等）已安装在当前活动环境中。

English

Using `--no-build-isolation` requires the build backend (setuptools, wheel, etc.) to already be installed in the active environment.

解决方案

  1. 90% 成功率 
    pip install --upgrade setuptools wheel && pip install --no-build-isolation <package>
  2. 95% 成功率 
    pip install <package>  # drop --no-build-isolation

无效尝试

常见但无效的做法:

  1. 90% 失败

    pip is separate from the build backend; reinstalling it does not add setuptools.

  2. 95% 失败

    The same missing backend error recurs deterministically.

  3. 90% 失败

    Force-reinstall affects the target package, not build-time imports.
