Question

我正在尝试从.whl文件安装Python包numpy。这个answer提供了使用pip / wheel安装包的语法：

pip install --use-wheel --no-index --find-links=/where/its/downloaded package_name

因此在downloading .whl文件之后重命名numpy.whl我会相应地遵循以下语法：

cd C:\Python27\Scripts
pip install --use-wheel --no-index --find-links=C:\Users\User Name\Downloads numpy

当我这样做时，我得到了

Ignoring indexes: https://pypi.python.org/simple
Exception:
Traceback (most recent call last):

我下载了numpy‑1.9.2+mkl‑cp27‑none‑win_amd64.whl文件并在64位架构上运行Python 2.7，所以我不认为我下载的版本是问题所在。我能想到的另一个问题是原始答案中的语法是linux编写的，我找不到处理Windows目录的示例。另一个问题可能是我的User Name是两个单词，其中有一个空格，Wheel没有设置处理。我尝试在空间前添加/，以防出现问题，但没有骰子。如何使用.whl文件在Windows上安装Python包？

从特定目录安装Python包.whl
