meshcat_visualizer_test 无法获取存储库 'yaml_cpp'

Question

我正在尝试运行 drake/bindings/pydrake/systems/test/meshcat_visualizer_test.py 按照所述文件顶部的注释说明，但我不熟悉如何添加 yaml-ccp，我相信会导致错误。我克隆了 drake 存储库并配置了 pydrake，并且能够运行服务器（第一个必需的命令），但不知道如何添加缺少的 yaml-cpp 包。

在命令行上尝试运行 /usr/bin/pkg-config yaml-cpp --libs，看看会发生什么。它应该不会报告任何错误，只打印 -lyaml-cpp.

您是否使用https://drake.mit.edu/ubuntu.html 命令安装了 Drake 的依赖项？那时它应该已经安装了 libyaml-cpp-dev，这应该是 pkg-config 成功所需的全部。
