在没有gcc或root访问权限的共享主机上安装需要gcc的python模块 [英] installing python modules that require gcc on shared hosting with no gcc or root access
问题描述
我将Hostgator共享用作生产环境，并且在使用以下命令后安装一些python模块时遇到问题:
I'm using Hostgator shared as a production environment and I had a problem installing some python modules, after using:
pip安装MySQL-python
pip install MySQL-python
pip安装枕头
结果:
无法执行gcc:权限被拒绝 错误:命令'gcc'失败，退出状态为1
unable to execute gcc: Permission denied error: command 'gcc' failed with exit status 1
服务器限制
- 无root访问权限
- sudo不起作用(sudo:有效uid不为0，sudo是否已安装setuid root?)
- 没有gcc
问题
-
是否有其他枕头包装.我希望它使用django ImageField. (就像pymysql可以替代mysql-python一样)
is there an alternative package for pillow. I want this to use django ImageField. (just like pymysql is an equally capable alternative for mysql-python)
我在根目录中安装了mysql-python和pil之类的模块，即不带任何virtualenv的pip冻结列出了这些模块.但是我无法在此根环境中安装其他必需的模块，也无法在virtualenv中安装mysql-python和pil.可以做些什么吗?我们可以以某种方式在virtualenv中导入/使用安装在根目录下的软件包吗?
i have modules like mysql-python and pil installed in root, i.e. pip freeze without any virtualenv lists these modules. but i cannot install my other required modules in this root environment and in my virtualenv i cannot install mysql-python and pil. can something be done? can we import/use packages installed in root somehow in a virtualenv?
是hostgator共享的，仅对PHP有好处，而对python/django webapps没有好处.我们的流量有限，因此我们正在使用hostgator共享.我们应该避免使用hostgator还是共享托管?它们对于python/django是否还不够好(我在托管静态/PHP网站方面没有任何问题).它们是否有太多的问题，局限性或性能问题(FCGI)?如果是的话，还有哪些替代方案?
is hostgator shared only good for PHP and not for python/django webapps. we have limited traffic so we are using hostgator shared. should we avoid hostgator or shared hosting? aren't they good enough for python/django (i had no problems in hosting static/PHP sites ever). are they too many problems and limitations or performance issues (FCGI)? if yes, what are the alternatives?
推荐答案
您可以尝试构建轮子在一些有gcc可用的类似主机上，将它们复制到您的服务器上并进行安装.但是我不知道应该有多少相似的主机.
You can try building wheels on some similar host where gcc is available, copy them to your server and install. But I do not know how much similar hosts should be.

在具有gcc的相似"主机上:
on "similar" host with gcc:
mkdir /tmp/wheels
mkdir /tmp/pip-cache
pip wheel --download-cache /tmp/pip-cache -w /tmp/wheels -r requirements.pip
mkdir /tmp/wheels
mkdir /tmp/pip-cache
pip wheel --download-cache /tmp/pip-cache -w /tmp/wheels -r requirements.pip
将轮子复制到您的主机(我假设您复制到/tmp/wheels)
copy wheels to your hosting (I assume that you copy to /tmp/wheels)
从车轮安装，忽略索引并使用车轮目录:
install from wheels ignoring index and using wheels dir:
pip install --download-cache /tmp/pip-cache --find-links=/tmp/wheels --no-index -r requirements-dev.pip
P.S.也许您还应该将下载缓存复制到您的托管中.我不记得是否需要这样做.如果不需要，则可以跳过选项--download-cache /tmp/pip-cache
P.S. Maybe you should also copy download-cache to your hosting. I do not remember if this is needed. If this is not needed then you can skip option --download-cache /tmp/pip-cache
