导入错误：导入聚合时 DLL 加载失败：找不到指定的模块

Question

我是 Python 新手，目前在导入某些库时遇到问题。

我正在使用 Python 3.8。

我已经使用“pip install pandas”在 CMD 中安装了 Pandas

如果我转到 Python 文件夹，我会看到已安装 Pandas：

C:\Users\VALENTINA\AppData\Local\Programs\Python\Python38-32\Lib\site-packages

但是当我尝试在我的脚本中导入 Pandas 时收到此错误消息：

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    import pandas as pd
  File "C:\Users\VALENTINA\AppData\Local\Programs\Python\Python38-32\lib\site-packages\pandas\__init__.py", line 55, in <module>

    import pandas._libs.window.aggregations as window_aggregations
ImportError: DLL load failed while importing aggregations: The specified module could not be found.

在 Visual Code 和 IDLE 中运行我的脚本时出现此错误消息。

如果有人可以帮助我，我很感激

谢谢

Answer 1

我面临同样的问题。我正在使用python 3.7.5. 默认pip install pandas命令安装版本 1.0.3。所以我恢复到 1.0.1 版。

pip uninstall pandas
pip install pandas==1.0.1

现在它可以正常工作了。你可以试试。

您也可以尝试安装更新版本的 Microsoft Visual C++ Redistributable。

例如（2015-2019）

我有同样的问题，安装上述解决了它。
