pydrake.tutorials ModuleNotFoundError: No module named 'pydrake'

Question

安装步骤为：

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，我遇到了这个错误：

~/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__)':

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

Answer 1

export PYTHONPATH=... 步骤必须在同一 command-line 终端中执行，因为稍后会尝试 python3 -m pydrake.tutorials。也许这就是问题所在？
