Pip install numpy 抛出 TypeError 异常 IronPython 2.7
Pip install numpy throws a TypeError Exception IronPython 2.7
我在一家公司实习，我有一个关于将 Python 集成到现有 C# 项目中的项目。因此，添加 NumPy 和 SciPy 这两个库非常重要。
由于旧的 Python 版本有一些限制，这就是为什么我有点挣扎。
所以我所做的是尝试通过 pip 安装 NumPy，如下所示：
pip install --proxy="proxy:port" numpy
我得到的是异常。我已经尝试升级 pip 因为我认为它可能会解决问题但没有成功。
有谁知道这个问题的原因是什么？

10 月 6 日更新：
我将用于安装 NumPy 的 pip install 命令更改为：
pip install --proxy="proxy:port" numpy==1.6.6
因为我知道这是兼容 python 2.7 的最后一个版本，但我没有成功。它抛出相同的错误，但抛出异常的文件不同：
pip install --proxy="xxx:port" --user numpy==1.6.6
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.

To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
