我创建了一个新的 Conda Env：

conda create -n my_env pip python=3.8.8

然后，激活我的环境

conda activate my_env

然后，如anaconda docs（here）中所述，尝试安装pwntools：

conda install -c conda-forge pwntools

我收到此错误消息：

D:\>conda install -c conda-forge pwntools

conda-forge 已经在频道中。

这是我的环境（conda 列表）的详细信息

我并没有真正理解这个错误的含义，而且由于我不希望任何环境错误在接下来的六个月内因为一个糟糕的解决方法而在后面咬我，我更愿意寻求一些建议。

显然这个错误并不常见（我已经向 pwntools discord channel 寻求帮助）。

有人可以帮助我理解错误的含义以及可行的解决方法吗？

谢谢！

使用mamba，问题更清楚（我已将 pwntools 添加到环境创建行：

Encountered problems while solving:
  - nothing provides ncurses needed by pwntools-4.3.1-pyh44b312d_0

所以问题是pwntools任何已配置通道的 Windows 上的依赖项都不可用。在这种特定情况下，不幸的是，您从 conda 安装时运气不佳，因为不知道ncursesWindows 上提供的任何频道。

你也许可以使用 pip 让它工作，至少我能做到

 pip install pwntools

创建环境后
