Question

我需要安装python连接器以运行脚本以将数据加载到Snowflake。当我运行命令“ pip install雪花连接器-python”时，出现很多错误与C编译器和numpy有关。 Python版本为3.8，pip也已升级。请帮助我解决软件包安装问题。

以下是命令提示符下的错误列表：

Answer 1

您似乎正在使用python 3.9。对于此设置，可以从您的错误消息中看到：

ERROR: Command errored out with exit status 1: 'c:\program files\python39\python.exe'

并且在安装numpy时失败，这可能很难从源代码编译，并且尚未针对python 3.9正式发布。

Python版本是3.8

至少您的设置使用的是3.9。版。在pypi上，snowflake-connector-python的所有文件仅使用python 3.7，但是您仍然可以尝试通过以下命令使用python 3.8从源代码进行安装：

c:\program files\python38\python.exe -m pip install snowflake-connector-python

（用您的python 3.8可执行文件的路径替换c:\program files\python38\python.exe）
