为什么我无法安装tensorflow？

Question

我确定我使用的是 3.6 版本，并且我尝试了一切。

这是我尝试过的：

py -m pip install tensorflow

ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none)
ERROR: No matching distribution found for tensorflow
PS C:\Users\skarl> pip install tensorflow
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none)
ERROR: No matching distribution found for tensorflow

[notice] A new release of pip is available: 23.2.1 -> 23.3.2

PS C:\Users\skarl> py -m pip install --upgrade pip
Requirement already satisfied: pip in c:\users\skarl\appdata\local\programs\python\python312\lib\site-packages (23.3.2)

我原以为它会起作用，但它没有。怎么了？

更仔细地阅读错误消息：

Defaulting to user installation because normal site-packages is not writeable

您似乎正在尝试将软件包安装到不允许的位置。也许您可以创建一个虚拟环境。否则请管理员帮助或以管理员身份运行终端。

To update, run: C:\Users\skarl\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.12_qbz5n2kfra8p0\python.exe -m pip install --upgrade pip

这表示使用参数运行Python

-m pip install --upgrade pip

，而不是像运行有效命令一样运行参数，这就是你尝试过的：

-m pip install --upgrade pip

那是行不通的。要么是这个：

python -m pip install --upgrade pip

但更有可能正是错误消息所建议的，使用 Python 的完整路径，因为它可能不在您的路径上（这通常是一件好事）。
