How to solve: AttributeError: 'FunctionInfo' object has no attribute 'fan_in' error in pydriller?

Question

我正在使用 pydriller 检索提交信息，但出现错误“AttributeError：'FunctionInfo' 对象没有属性 'fan_in'。你有什么解决办法吗？

执行代码-

from pydriller import RepositoryMining

for commit in RepositoryMining (path_to_repo='https://github.com/openssl/openssl', only_commits=['9cedfc90cebc905b20275d534699a1070bba65a4']).traverse_commits():
    commit_row = {
        'hash': str(commit.hash),
        'msg': str(commit.msg),
        'author_date': str(commit.author_date),
        'merge': str(commit.merge),
        'dmm_unit_size': str(commit.dmm_unit_size)
    }
    print(commit_row)

我得到以下错误输出：-

AttributeError: 'FunctionInfo' object has no attribute 'fan_in'

我找到了问题的原因，这与解释器的问题有关。我在IDE.

中将Python解释器改成3.8版本后问题解决
