python - pip install 编译成功后执行导入错误

Question

我的烦恼

在干净的 Ubuntu 16.04 环境中，我想安装和使用 Crossbar.io。

我已经有从 ppa、virtualenv 安装 pypy并激活一个新的 pypy virtualenv。

通过命令 pip install crossbar 安装交叉开关时出现一些错误但使用此构建命令解决了:

pip install --no-cache-dir --global-option=build_ext --global-option="-I/usr/include/python2.7" crossbar

现在使用 crossbar version 启动横杆时我收到以下错误:

我尝试在启动前通过设置环境变量添加路径但没有成功:

你有什么想法吗？

Answer 1

您不应该将 cpython header 与 pypy 一起使用，因此 --global-option="-I/usr/include/python2.7"是错的。如记录 here和 here您可能需要安装 pypy-dev包，以便您可以使用 pypy 构建包，正如您所需要的 python-dev至
用python构建包。

编辑:查看横杆 documentation , 他们不推荐使用 apt get完全没有，并且还建议从源代码编译 CPython，这就是为什么没有提及 python-dev 的原因。包裹。
