我的麻烦

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

我已经从ppa，virtualenv 安装了pypy并激活了一个新的pypy virtualenv。

我在通过命令pip install crossbar安装crossbar时遇到了一些错误，但使用此构建命令解决了这个错误：

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

现在，当使用crossbar version启动crossbar时出现以下错误：

Traceback (most recent call last):

我尝试在启动之前按设置环境变量添加路径，但没有成功：

export LD_LIBRARY_PATH=/usr/lib/python2.7/config-x86_64-linux-gnu/:/usr/lib/x86_64-linux-gnu/

你有什么想法吗？

Answer 1

您不应该使用ppyy的cpython标头，因此--global-option="-I/usr/include/python2.7"是错误的。正如文档here和here所示，您可能需要安装pypy-dev包，以便您可以使用pypy构建包，就像您需要python-dev一样用python构建包。

编辑：查看横杆documentation，他们根本不建议使用apt get，还建议从源代码编译CPython，这就是为什么没有提到python-dev封装

Answer 2

使用@mattip响应解决：通过apt-get install pypy-dev安装pypy-dev软件包并再次运行pip install以使用良好的库pip install --no-cache-dir crossbar重建模块。

现在它对我有用了！

成功后执行导入错误pip install compilation
