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

这个问题通常是由于您在没有管理员权限的环境中安装软件包导致的。当您尝试在无法写入系统级安装目录的情况下进行安装时，Python会自动将软件包安装到用户级安装目录中。

用户级安装目录位于您的用户主目录下的`.local`文件夹中。这样安装的软件包只能对当前用户可见，不会影响其他用户或整个系统。

如果您想避免显示此警告消息，您可以尝试以下解决方法之一：
1. 以管理员权限运行命令提示符或终端，并使用`sudo`（对于Linux和Mac）或以管理员身份运行命令提示符（对于Windows）来安装软件包。
2. 使用 `virtualenv` 或 `conda` 等工具创建一个虚拟环境，并在其中进行安装。这样可以将软件包限定在虚拟环境中，而不会影响系统级安装目录。

希望这些解决方法能帮助到您！如果您还有其他问题，请随时提问。

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

As an AI language model, I cannot determine the exact context of your message or the program you are running. However, I can provide a general explanation of the message you are seeing.

The message "Defaulting to user installation because normal site-packages is not writeable" typically appears when you are trying to install a Python package using pip, but you don't have permission to write to the system-wide package directory.

By default, pip will install packages into the system-wide package directory, which requires administrator or superuser privileges. If you don't have these privileges, pip will instead install packages into a user-specific directory, which doesn't require special permissions.

This message is simply informing you that pip is installing the package into the user-specific directory rather than the system-wide directory. It's not necessarily an error, but it does indicate that you may not have full system access and may need to take additional steps to ensure that the package works properly.

If you have any further questions or concerns, please provide more information about your specific situation and I will do my best to assist you.
