python軟件包安裝給出“錯誤：命令'gcc'失敗，退出狀態為1”

Question

我正在嘗試使用python2.7在Ubuntu上安裝一個名為mlabwrap-1.1的python軟件包。 但是，安裝失敗並報告：

error: command 'gcc' failed with exit status 1

注意：前一陣子我更新了numpy並收到了很多警告，但是我不知道這是否與此有關。

那么可能是什么問題呢？

一些細節

Linux版本3.2.0-49-通用（build @ komainu）（gcc版本4.6.3（Ubuntu / Linaro 4.6.3-1ubuntu5））＃75-Ubuntu SMP Tue Jun 18 17:39:32 UTC 2013

我得到的確切錯誤：

Answer 1

我以前有過這個，需要安裝libevent-dev。

apt-get install libevent-dev

我現在無法檢查，但是我認為值得嘗試。

Answer 2

您正在安裝需要C擴展名的python軟件包，因此它至少需要像gcc這樣的C編譯器。 現在在numpy的特定情況下，我建議使用打包的apt-get install python-numpy ，但是如果出於某些原因您不想這樣做，我將使用apt-get build安裝所有必需的軟件包-dep python-numpy ，然后重新運行安裝。 由於您看起來像python新手，因此建議您開始使用virtualenv而不是在全局安裝庫。
