pydrake.tutorials ModuleNotFoundError:没有名为“pydrake”的模块

Question

安装步骤如下：

git clone https://github.com/RobotLocomotion/drake.git
mkdir drake-build
cd drake-build
cmake -DWITH_GUROBI=ON -DWITH_MOSEK=ON ../drake
make -j4
cd drake-build
export PYTHONPATH=${PWD}/install/lib/python3.8/site-packages:${PYTHONPATH}

当我尝试python3 -m pydrake.tutorials时，我得到了以下错误：

~/git/drake-build$ python3 -m pydrake.tutorials
/usr/bin/python3: Error while finding module specification for 'pydrake.tutorials' (ModuleNotFoundError: No module named 'pydrake')

当我使用python3 -c 'import pydrake; print(pydrake.__file__)'时

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'pydrake'

Answer 1

export PYTHONPATH=...步骤必须在以后尝试的python3 -m pydrake.tutorials命令行终端中执行。也许这就是问题所在？
