【问题描述】：

我已经以管理员身份运行实例化了 osgeo4w，但它仍然给了我权限被拒绝。我正在尝试在 Quantum GIS 2.8 上安装 pandas，我已经使用 pip 命令安装了 sklearn，它已成功安装。

但是当我尝试安装 pandas 时，出现如下错误：

  C:\Windows\System32>pip install pandas

有什么解决办法吗？

【解决方案1】：

如果有人（比如我）发现这篇文章有用...

将熊猫从 0.18 升级到 0.20 时，我遇到了同样的问题 pip install --upgrade pandas.

问题：numpy 和 pandas 安装程序想要编写已存在于 ../site-packages/numpy 和 ../site-packages/pandas 文件夹中的较新文件。

由于某种原因，shutil 无法以 'wb' 模式打开这些文件。

虽然满足numpy>=1.7.0的要求，但使用“--upgrade”也可以升级numpy。

解决方案：

为了避免IO Error: [Errno 13] Permission denied: ...，请将numpy和pandas都卸载，然后重新安装（numpy优先）：

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