"错误:命令'x86_64-linux-gnu-gcc'以退出状态1失败"在virtualenv中

为我工作:
首先安装python2.7-dev
sudo apt-get install python2.7-dev

我python2.7-dev通过Linux Mint 17中的Synaptic Package Manager 安装.

然后我可以完成以下任务virtualenv:

pip install pillow
pip install pycrypto

然后我通过Synaptic 安装libxml2-dev并libxslt1-dev完成以下操作:

pip install lxml

我也这样做,以便pymongo安装没有任何错误:

pip uninstall pymongo
pip install pymongo  # i defined the version i needed ie pip install pymongo==2.6.2

我仍然很困惑这是如何解决问题的,因为我认为这virtualenv是一个孤立的环境.任何关于此的澄清都表示赞赏.

大多数情况下,这些是依赖性问题.

在gcc编译器的堆栈跟踪之后,可以看到丢失的文件.有时安装Python开发包是不够的.

例如:我试图pip install requests[security]在我的virtualenv foo中做.这是pip-installer给我的结果.

重要的是: #include <openssl/aes.h>

编译器非常清楚它要求这个文件 - 但它不存在于文件系统中.

知道了,剩下要做的就是:安装所需的库!

找出您的发行版所需的软件包:例如,对于Ubuntu,您可以访问Ubuntu软件包搜索站点并输入您要查找的丢失文件.在这种情况下" aes.h "

使用您的发行包管理工具安装所需的包:例如,对于Ubuntu:

aptitude install libssl-dev

在你的virtualenv中重试pip:

pip install requests[security]
