在没有pip

Question

我以通常的方式为所有项目使用virtualenv：创建项目文件夹，创建virtualenv，通过pip安装所需的包。

但是我现在正在尝试将pyql（https://github.com/enthought/pyql）安装到virtualenv中，但它不能通过pip获得。我通过在我的系统上安装标准的QuantLib c ++库来遵循入门指令（https://github.com/enthought/pyql/blob/master/docs/source/getting_started.rst），现在我需要安装pyql。

我从git下载了pyql，但问题是我不想只运行make build和make test，因为这会将pyql安装到我的系统python上。我想将它安装到virtualenv中。我怎么做？我只使用pip将软件包安装到virtualenv中。

更新：

我已经激活了virtualenv然后运行make build，它提供了以下内容：

python setup.py build_ext --inplace

如上所述，我根据需要安装了quantlib c ++库。然后在virtualenv中我安装了cython。

错误的第二行提到/usr/local/lib/python3.3。难道不是在virtualenv中使用python吗？

看起来Makefile https://github.com/enthought/pyql/blob/master/Makefile在构建期间调用python，所以只要你{virt {1}}

激活你的virtualenv就可以了。
