在Dreamhost上使用virtualenv更新新的Django和Python 2.7。*

我目前有私人服务器，一个外壳帐户和一点运气。所以这是我的工作：

1. SSH到你的主机以升级python

 cd ~ mkdir tmp cd tmp wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz tar zxvf Python-2.7.3.tgz cd Python-2.7.3 ./configure --enable-shared --prefix=$HOME/Python27 --enable-unipre=ucs4 make make install

1. 配置系统以使用我们的新Python。打开〜/ .bashrc并添加以下行

 export PATH="$HOME/Python27/bin:$PATH" export LD_LIBRARY_PATH=$HOME/Python27/lib #save it and run source ~/.bashrc

你现在可以使用检查你的python版本 which python

1. 安装easy_install，pip

cd ~/tmpwget http://peak.telecommunity.com/dist/ez_setup.pypython ez_setup.pyeasy_install pip# Or even shorterwget https://bootstrap.pypa.io/get-pip.pypython get-pip.py

1. 安装 virtualenv

 pip install virtualenv virtualenv $HOME/<site>/env #Switch to virtualenv source $HOME/<site>/env/bin/activate

1. 你还可以将env路径添加到 bashrc

 export PATH="$HOME/<site>/env/bin/:$PATH" source ~/.bashrc

1. 安装django和其他所有东西

 pip install django pip install .... pip install .... pip install ....

1. 建立专案

 cd $HOME/<site>/ python $HOME/<site>/env/bin/django-admin.py startproject project

1. 创建passenger_wsgi.py于HOME//与下列内容

 import sys, os cwd = os.getcwd() sys.path.append(cwd) sys.path.append(cwd + '/project')  #You must add your project here or 500 #Switch to new python #You may try to replace $HOME with your actual path if sys.version < "2.7.3": os.execl("$HOME/<site>/env/bin/python",     "python2.7.3", *sys.argv) sys.path.insert(0,'$HOME/<site>/env/bin') sys.path.insert(0,'$HOME/<site>/env/lib/python2.7/site-packages/django') sys.path.insert(0,'$HOME/<site>/env/lib/python2.7/site-packages') os.environ['DJANGO_SETTINGS_MODULE'] = "project.settings" import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler()

或者这样

import sys, osbase_DIR = os.path.dirname(os.path.abspath(__file__))sys.path.append(os.path.join(base_DIR))  #You must add your project here or 500#Switch to new python#You may try to replace $HOME with your actual pathPYTHON_PATH = os.path.join(base_DIR, 'env', 'bin', 'python')if sys.executable != PYTHON_PATH:    os.execl(PYTHON_PATH, "python2.7.12", *sys.argv)

如果你使用的是django 1.7，请将最后两行替换为

from django.core.wsgi import get_wsgi_applicationapplication = get_wsgi_application()

享受：D
Dreamhost上的新版本python将不再返回，sys.executable因此你这是我的passenger_wsgi版本

import sys, osVIRTUAL_ENV_PYTHON = 'venv-python'  # Python > 2.7.6 dreamhost not return sys.executablebase_DIR = os.path.dirname(os.path.abspath(__file__))def is_venv_python():    if len(sys.argv) > 0:        last_item = sys.argv[len(sys.argv)-1]        if last_item == VIRTUAL_ENV_PYTHON: return True    return Falsesys.path.append(os.path.join(base_DIR))  #You must add your project here or 500#Switch to new pythonPYTHON_PATH = os.path.join(base_DIR, 'env', 'bin', 'python')if not is_venv_python():    os.execl(PYTHON_PATH, "python2.7.12", *sys.argv + [VIRTUAL_ENV_PYTHON])sys.path.insert(0, os.path.join(base_DIR, 'env', 'bin'))sys.path.insert(0, os.path.join(    base_DIR, 'env', 'lib', 'python2.7', 'site-packages'))
