Question

我对python很陌生，想开始在python中使用pysftp模块。但是，当在下面找到说明时

here https://www.pythonforbeginners.com/modules-in-python/python-secure-ftp-module

我相信由于超时而无法解决问题，但是我不知道如何理解。

Answer 1

经过大量的反复试验，我列出了行得通和不行的内容：

什么有效？

conda install pysftp

什么不起作用？

pip install pysftp

python -m pip install pysftp

Answer 2

我在使用 conda 安装 pysftp 时遇到问题，因为没有可用的 linux-armv7l 包。

我通过以下方式解决了：

apt-get install paramiko
pip install pysftp

pip 包与 paramiko 有一些依赖关系。也许它也适用于不同的架构
