pip安裝成功編譯后執行導入錯誤

Question

我的麻煩

在干凈的Ubuntu 16.04環境上，我想安裝和使用Crossbar.io。

我已經從ppa，virtualenv安裝了pypy並激活了一個新的pypy virtualenv。

通過命令pip install crossbar安裝crossbar時出現一些錯誤，但使用以下build命令解決了：

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

現在，當使用crossbar version啟動crossbar時，出現以下錯誤：

Traceback (most recent call last):

我嘗試在啟動前通過設置環境變量添加路徑，但沒有成功：

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

你有什么想法嗎？

Answer 1

您不應該在pypy中使用cpython標頭，因此--global-option="-I/usr/include/python2.7"是錯誤的。 如此處和此處所述，您可能需要安裝pypy-dev軟件包，以便可以使用pypy構建軟件包，就像使用python-dev來構建python軟件包一樣。

編輯：查看crossbar 文檔 ，他們根本不建議使用apt get ，也建議從源代碼編譯CPython，這就是為什么沒有提到python-dev包的原因。

Answer 2

使用@mattip響應解決：通過apt-get install pypy-dev安裝pypy-dev軟件包，然后再次運行pip install以使用良好的庫重建模塊pip install --no-cache-dir crossbar 。

現在對我來說很好！
