未禁用pip缓存时，get\u python\u lib（）返回不正确的路径

Question

当要安装的包已存在于缓存中时，get_python_lib()返回不正确的路径。你知道吗

我的机器中安装了Anaconda和单独的Python。你知道吗

1. 当我从带有pip缓存的独立Python安装时，我看到以下内容： 命令：pip install ibm_db

get_python_lib()中的用法设置.py->；https://github.com/ibmdb/python-ibmdb/blob/master/IBM_DB/ibm_db/setup.py#L242

data_files = [ (get_python_lib(), ['./README.md']),
               (get_python_lib(), ['./CHANGES']),
               (get_python_lib(), ['./LICENSE']),
               (get_python_lib(), ['./config.py.sample'])]

data_files在同一脚本中传递给setup(..)。你知道吗

get_python_lib()通过以下方式安装时行为正确： 命令：pip --no-cache-dir install ibm_db。你知道吗

文件在以下位置正确复制：

Python：

有人知道这种行为和可能的解决办法吗？ 是否有其他更好的替代方法来获取当前站点包的安装路径？你知道吗
