在 Linux EC2 实例中使用 sudo pip3 install python-binance 时 python-binance 无法编译错误

Question

更新 1: 我正在 Linux AWS EC2 实例上安装 python-binance，当我尝试在 Python 3.7.0rc1 中使用 pip3 安装 python-binance 时，出现以下错误。我使用了以下命令。

sudo pip3 install python-binance

安装包一切正常，直到出现以下部分输出。

我之前已经在 Mac 和 Windows 机器上成功安装了 python-binance，但不知道发生了什么。

然后我按照下面的评论安装了 gcc，并收到以下错误:

Answer 1

在有人指出我需要安装 gcc 后，事情有了进展，然后我发现我遇到了 SSL 错误。我必须执行以下操作:

sudo pip3 uninstall pyopenssl

要删除并升级麻烦的软件包，然后:

sudo pip3 uninstall cryptography

之后 python-binance 就安装成功了。问题是它安装到 python 2.7 而不是 3.7。
