如何在Ubuntu 17.04上的Pypy virtualenv中安装iPython

我正试图在一个virtualenv中安装IPython。我已经将我的Virtualenv设置为使用PyPy2.7而不是CPython3

当我使用由apt get安装的IPython时，它最终使用的是cpython3而不是Pypy

---

当我尝试

pip安装ipython

时，我得到一个编译错误，因为它找不到

Python.h

头文件。此错误详细信息如下：。建议的修复会导致以下错误：

无法执行'--user'安装。用户站点包在此virtualenv中不可见

完全错误：

在创建virtualenv之前，您需要安装pypy dev。您可以看到gcc命令正在/home/me/Documents/pypy-ipython-venv/include中查找include文件，我担心只有在创建虚拟环境时存在头文件时，目录才会正确填充。您可以通过查看该目录的内容来证明这一点，它应该有一个Python.h文件

请注意，您只需要安装pypy-dev一次，然后就可以使用尽可能多的VirtualNV了
