Answer 1

吧台前面需要一个圆点。。：-（

bar = import_module('.bar', package='project')

Answer 2

import_lib的文档说明

If the name is specified in relative terms, then the package argument must be specified to the package which is to act as the anchor for resolving the package name (e.g. import_module('..mod', 'pkg.subpkg') will import pkg.mod).

因此，表达式也可以写成

bar = import_module('..bar',package='project.bar')
