Virtualenv - DeprecationWarning：不推荐使用imp模块以支持importlib

Question

我正在使用pipenv安装beautifulsoup，由于某种原因我得到了弃用警告。 （对于上下文，我使用brew安装python，使用pip3安装pipenv）：

我该如何解决这个问题？

Answer 1

我也遇到了同样的问题，但我的情况是sklearn Library，为了修复警告，这就是我所做的（你也可以这样做）：

1. 使用名为cloudpickle.py的编辑权限打开该文件，该权限位于此位置\sklearn\externals\joblib\externals\cloudpickle\cloudpickle.py
2. 将import imp和from imp import find_module替换为文件顶部的import importlib。
3. 找到名为find_module的函数，并用file, path, description = find_module(path)替换file, path, description = importlib.utils.find_spec(path)行

所以，总而言之，你必须在文件中用imp module替换importlib的提及错误。在您的情况下，该文件存在于/usr/local/lib/python3.7/site-packages/virtualenv.py

您可以参考https://docs.python.org/3/library/imp.html和https://docs.python.org/3/library/importlib.html#module-importlib获取有关该模块的更多信息。

我也面临同样的问题。在我的Linux机器上，我只是删除已安装的软件包numpy和pandas并重新安装。最后我的问题解决了..

试试这个..

pip uninstall pandas
pip uninstall numpy
pip install pandas
pip install numpy
