我无法在 Windows 10 命令提示符上安装 sklearn、numpy 和 scipy 以在 Python 3.6 上使用

Question

我已经正确安装了 Python 3.6，并且一直在使用 Eclipse。但是我不能使用这些库。每次导入它们时，我都会收到一条错误消息：

Traceback (most recent call last):
  File "C:\Users\gilbe\eclipse-workspace\python3.6\BeginnerFiles\IrisDataSet", line 1, in <module>
    from sklearn import datasets
ModuleNotFoundError: No module named 'sklearn'`

当我尝试安装 sklearn、numpy 和 scipy 时，我在 Windows 命令提示符中输入以下内容：

"pip install numpy", "pip install scipy", or "pip install sklearn".

但是，我每次都收到错误消息。例如：

C:\Program Files (x86)\Python36-32\Scripts>pip install sklearn

You are using pip version 9.0.3, however version 10.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

此外，当我尝试使用上面建议的命令升级 pip 命令时，我也收到错误消息：

我真正的问题是如何解决这些问题，并正确安装这些库，我花了一整天的时间尝试以不同的方式解决这个问题，包括：从 Eclipse 内部安装库, 通过 Window>Preferences>Interpreter>Python Interpreter>Install with pip ，卸载并重新安装 Python，尝试使用 easy_install <package> 命令。

请帮忙。

Answer 1

右键单击屏幕左下方的 windows 按钮。然后转到“Windows PowerShell(Admin)。在那里你尝试你的 pip 安装。它肯定会起作用。我认为您没有管理员权限，这就是您看到的原因。

PermissionError: [WinError 5] Access is denied

只需使用管理员身份打开 cmd user.Hope 这有帮助。
