Pandas 未安装在 64 位 Windows 中

Question

我最近在 Windows 笔记本电脑上安装了新版本的 Anaconda 3 4.2。 所有的包都运行良好，但从第一天开始，pandas 就没有为我工作过。 所以我想到了卸载并安装新版本的pandas 0.19

While using pip:
C:\Users\>python -m pip install --user pandas
Collecting pandas
  Using cached pandas-0.19.2-cp35-cp35m-win_amd64.whl
Exception:

Answer 1

问题是您尝试以普通用户身份安装 Pandas，因此无法更改 Anaconda 安装文件夹（Python 安装包所在的位置）的内容。您需要以管理员身份运行 CMD 或 PowerShell（无论您使用哪个）。在开始菜单中右键单击它的快捷方式，然后单击“以管理员身份运行”，然后再次运行相同的命令。

Answer 2

尝试使用 Anaconda 包管理器 - conda 而不是 pip：

C:\> conda install pandas
