Eigen::internal::plain_array＜T, Size, MatrixOrArrayOptions, 32＞::plain_array() [with T = double；

在ROS2上使用Eigen库时，出现如下报错：

/usr/include/eigen3/Eigen/src/Core/DenseStorage.h:128: Eigen::internal::plain_array<T,
 Size, MatrixOrArrayOptions, 32>::plain_array() [with T = double; int Size = 4; int 
MatrixOrArrayOptions = 0]: Assertion 
`(internal::UIntPtr(eigen_unaligned_array_assert_workaround_gcc47(array)) & (31)) == 0 && 
"this assertion is explained here: " "http://eigen.tuxfamily.org/dox-
devel/group__TopicUnalignedArrayAssert.html" " **** READ THIS WEB PAGE !!! ****"' failed.

 根据提示看这个网页：eigen.tuxfamily.org

 根据提示，直接将CMakeLists中的C++版本改成C++17,即可解决错误。
