重新安装Python后找不到Pandas模块

在我的系统上进行了一些更改后，Python无法再找到Pandas。我将首先掩盖错误，然后再尝试解决此问题。

错误-如果我正确阅读此内容，Python.exe找不到熊猫...系统-Hyper-v 2016，Python 3.5.4，Pandas 0.23安装到c：\ Python35。

问题-以前在不同位置安装了Python实例。C:\Program Files etc在安装3.5.4之前，我已删除了这些目录并删除了目录，但我怀疑某个地方有参考。

故障排除。

识别正确的版本

`C:\Python35>python
Python 3.5.4 (v3.5.4:3f56838, Aug  8 2017, 02:17:05) [MSC v.1900 64 bit         (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.r`

系统看到正确的位置

import os, sys
folder=os.path.dirname(sys.executable)
print(folder)here

其他

我尝试用pip install --ignore-installedpandas重新安装pandas，它说成功完成了。

我检查了目录C:\Python35\Lib\site-packages\pandas\core。错误中提到的所有* .py文件都存在。

我正在运行的脚本可在安装了P3.5.4的W10计算机上使用c:\Python35。

该pip freeze命令显示pandas 0.23.0安装

任何有关如何排除故障的提示
