TypeError：在 Ironpython 包安装中不期望类型“<type 'bytes'>”

Question

我正在尝试使用以下命令为 IronPython 2.7 安装一些软件包：

>C:\Program Files\IronPython 2.7\> ipy -X:Frames -m pip install (PackageName)

而且我不断收到这些错误消息块。

我不知道这意味着什么。我完全被难住了。

当我尝试将 pythonnet 连接到 IronPython for Visual Studio 时，就会发生这种情况。 Pip 在标准 Python 上对我来说工作得很好，但这只发生在 IronPython 上。

它们是什么意思？这里有什么问题？我该如何解决这个问题？

PS：这发生在我的 Windows 10 笔记本电脑上。

我在这个问题之后解决了这个问题： Why does IronPython tell me that pip is a package and not an executable?

可能你和我一样升级了 IronPython pip。

1. 删除 Lib/site-packages 中有关 pip 和 setuptools 的任何内容
2. 运行ipy -X:Frames -m ensurepip

现在你应该可以通过 pip 安装了。
