Question

当我sudo pip install pyquery，sudo pip install lxml和sudo pip install cython时，我会得到非常相似的输出，并显示相同的错误：

x86_64-linux-gnu-gcc: error: unrecognized command line option ‘-fstack-protector-strong’

这里是sudo pip install pyquery的完整点子输出：

我已查看this，this，this和this寻求帮助，但我无法解决问题爱好。

我已经安装了 libxml2-dev，libxslt1-dev和python-dev 。我在DigitalOcean Droplet上运行 Debian 7.0 x64 。

我只是想安装pyquery。有人可以帮帮我吗？

Answer 1

当我尝试将我的pandas版本升级到0.15.2

时遇到了这个问题

如果您安装gcc-4.9，您的系统上可能仍会有旧版本的gcc（在我的情况下为gcc-4.7）。

我可以想出解决这个问题的3种方法：

a）symlink / usr / bin / x86_64-linux-gnu-gcc to /usr/bin/x86_64-linux-gnu-gcc-4.9 如果您想更有条理地使用 update-alternatives ，请参阅https://askubuntu.com/questions/26498/choose-gcc-and-g-version

b）弄清楚如何手动指定哪个编译器pip使用并在某种类型的.conf文件中设置它 - 我没有检查过这个文件的位置，或者是否有pip的CLI选项可以完成等价物。原则上，创建/编辑/usr/lib/pythonX.Y/distutils/distutils.cfg应该这样做。当我尝试使用这种方法时，我遇到了问题。

c）编辑/usr/lib/python2.7/plat-x86_64-linux-gnu/_sysconfigdata_nd.py以反映您更新的编译器

我选择快速而肮脏的解决方案（a）强制一切正常工作

root@localhost:/home/user1$ rm /usr/bin/x86_64-linux-gnu-gcc
root@localhost:/home/user1$ ln -s /usr/bin/gcc-4.9 /usr/bin/x86_64-linux-gnu-gcc
root@localhost:/home/user1$ pip install pandas --upgrade
. . .  pandas compiles with gcc-4.9 here . . .

将事情移回原来的

root@localhost:/home/user1$ rm /usr/bin/x86_64-linux-gnu-gcc
root@localhost:/home/user1$ ln -s /usr/bin/gcc-4.7 /usr/bin/x86_64-linux-gnu-gcc

Answer 2

一种可能的解决方案是使用GCC 4.9或更高版本，它支持-fstack-protector-strong标志。

Answer 3

我没有升级到GCC 4.9，而是试图找到定义标志的位置并将其删除。在Debian Wheezy上，我在/usr/lib/python2.7/plat-x86_64-linux-gnu/_sysconfigdata_nd.py中找到它，它属于libpython2.7-minimal包。我的解决方案是在此文件中用-fstack-protector替换所有出现的-fstack-protector-strong。然后pip install执行了正确的构建命令。
