根因分析

CMake 使用 -GNinja 调用，但 Ninja 未安装或不在 PATH 中，或者 CMake 安装不包含 Ninja 生成器（例如，最小安装）。

English

CMake was invoked with -GNinja but Ninja is not installed or not in PATH, or the CMake installation does not include the Ninja generator (e.g., minimal install).

解决方案

  1. 安装 Ninja：在 Ubuntu 上运行 'sudo apt-get install ninja-build'；在 macOS 上运行 'brew install ninja'；在 Windows 上从 https://ninja-build.org/ 下载并添加到 PATH。
  2. 使用其他生成器，例如 Unix Makefiles：cmake -G "Unix Makefiles" ..
  3. 如果 Ninja 已安装但不在 PATH 中，请指定完整路径：cmake -G Ninja -DCMAKE_MAKE_PROGRAM=/usr/local/bin/ninja ..

无效尝试

常见但无效的做法:

  1. Reinstalling CMake without selecting the Ninja generator option 90% 失败

    The Ninja generator is part of CMake's built-in generators; a reinstall without ensuring Ninja is in PATH does not help.

  2. Setting CMAKE_GENERATOR to Ninja in CMakeLists.txt 95% 失败

    The generator is selected before CMakeLists.txt is parsed, so this setting has no effect; the error occurs at the configuration stage.

  3. Using -G "Ninja Multi-Config" as a substitute 85% 失败

    If Ninja is not installed, the multi-config generator also fails because it requires the same underlying build tool.
