Building Drake From Source Fails With "ModuleNotFoundError: No module named 'yaml'"
Building Drake From Source Fails With "ModuleNotFoundError: No module named 'yaml'"
我正在按照此处的说明进行操作：https://drake.mit.edu/from_source.html。我已经运行
./setup/mac/install_prereqs.sh
在我的 python virtualenv (drake-venv) 中它成功了。然后我设法用 Bazel 构建并 运行 斜面示例。但是尝试构建其他一些示例会导致涉及 YAML 的错误，如下所示：

但考虑到在终端中导入 yaml 是可行的，我不确定为什么会这样：
(drake-venv) benq:acrobot % which python
/Users/benq/Documents/drake/drake-venv/bin/python
(drake-venv) benq:acrobot % python --version
Python 3.9.10
(drake-venv) benq:acrobot % python -c 'import yaml'
(drake-venv) benq:acrobot %
我已经尝试重新安装 PyYaml 但没有帮助。

错误消息中的 lcm_vector_gen 是一个 code-generation 工具，它是 运行 作为构建的一部分。
它可能不服从你的 which python，而是使用 https://github.com/RobotLocomotion/drake/blob/master/tools/py_toolchain/interpreter_paths.bzl 的 hard-coded /usr/local/bin/python3.9。
我们不 运行 也不在虚拟环境中测试我们的构建，因此您遇到了一个新情况。
