在 python3 中安装 pyhs2 的问题

Question

我正在使用 CentOS 6.5 并想访问远程配置单元服务器。但我无法使用pip install pyhs2 安装pyhs2。

我已经安装了所有必需的依赖项：

• gcc-c++
• python-devel.x86_64
• cyrus-sasl-devel.x86_64

但我仍然得到同样的错误：

Answer 1

这是 Python3 和依赖项 SASL 的问题。 SASL 目前是为 Python2 编码的。这可以从错误“PyString_AsString 未在范围内声明”中看到。

如果可能的话，一个短期的解决方案是使用 Python2。从长远来看，需要为 Python3 更新 SASL 依赖项，或者 pyhs2 需要使用不同的依赖项。

Answer 2

快速更新： 看来现在可以使用 pip-Python3（我尝试使用 3.5 和 3.6）“安装”这个模块。

但是，即使安装了它，您也无法在 Python3 中使用它，因为该模块从未被移植到该版本（例如，它仍然使用“cStringIO”模块，该模块在 Python3 中不再存在） .

由于 pyhs2 不再维护（请参阅 https://github.com/BradRuderman/pyhs2 中的注释），您被 Python2 卡住了，或者您最好切换到另一个工具来连接到 HiverServer2。
