环境:Linux Mint 17 Cinnamon。
显示此错误:
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
在
virtualenv 中尝试以下操作时:
pip install lxml
pip install pillow
pip install pycrypto
pip install pymongo (fails but still shows in pip freeze)
这里有几个解决方案推荐安装
python2.7-dev :
Installing Pillow error: Setup script exited with error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
Installing lxml in virtualenv via pip install error: command 'x86_64-linux-gnu-gcc' failed
Pillow installation error: command 'gcc' failed with exit status 1
fatal error: Python.h: No such file or directory
然而，我对这个建议感到困惑，因为我的理解是使用类似的东西:
sudo apt-get install python2.7-dev
会将它添加到 Python 的主要 *system* 实例，而不是
virtualenv 中的那个。 . (见 -
https://unix.stackexchange.com/a/56392/92486)
我可以加
python2.7-dev刚到
virtualenv版本的Python？
请您参考如下方法:
大多数情况下，这些都是依赖问题。
按照 gcc 编译器的堆栈跟踪可以看到丢失的文件。有时安装 Python 开发包是不够的。
例如:
我试着做 pip install requests[security]在我的 virtualenv foo 中。这是 pip-installer 给我的结果。

重要的部分是:
#include <openssl/aes.h>
编译器非常清楚地表明它需要这个文件 - 但它不在文件系统中。
知道了，剩下要做的就是: 安装所需的库!
例如对于 Ubuntu 你可以去 The Ubuntu Package Search Site并输入您要查找的丢失文件。在这种情况下，“ aes.h ”
例如对于 Ubuntu:
aptitude install libssl-dev pip install requests[security]
