在Dreamhost上使用virtualenv更新新的Django和Python 2.7。*（带乘客）

如何解决在Dreamhost上使用virtualenv更新新的Django和Python 2.7。*（带乘客）？

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：

SSH到您的主机以升级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=$HOME/Python27 –enable-unicode=ucs4
make
make install
配置系统以使用我们的新Python。打开〜/ .bashrc并添加以下行
```
 export PATH="$HOME/Python27/bin:$PATH"
```
export LD_LIBRARY_PATH=$HOME/Python27/lib

#save it and run
source ~/.bashrc

您现在可以使用检查您的python版本 which python

安装easy_install，pip
```
cd ~/tmp
```
wget http://peak.telecommunity.com/dist/ez_setup.py
python ez_setup.py
easy_install pip

Or even shorter

wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py
安装 virtualenv
```
 pip install virtualenv
```
virtualenv $HOME//env
#Switch to virtualenv
source $HOME//env/bin/activate

您还可以将env路径添加到 bashrc

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

安装Django和其他所有东西
```
 pip install django
```
pip install ....
pip install ....
pip install ....
建立专案
```
 cd $HOME/<site>/
```
python $HOME//env/bin/django-admin.py startproject project
创建passenger_wsgi.py于HOME/<site>/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//env/bin/python”,
“python2.7.3”, *sys.argv)

sys.path.insert(0,’$HOME//env/bin’)
sys.path.insert(0,’$HOME//env/lib/python2.7/site-packages/django’)
sys.path.insert(0,’$HOME//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, os

BASE_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 path
PYTHON_PATH = os.path.join(BASE_DIR, 'env', 'bin', 'python')
if sys.executable != PYTHON_PATH:
    os.execl(PYTHON_PATH, "python2.7.12", *sys.argv)

如果您使用的是django 1.7，请将最后两行替换为

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

享受：D

Dreamhost上的新版本python将不再返回，sys.executable因此您这是我的passenger_wsgi版本

import sys, os

VIRTUAL_ENV_PYTHON = 'venv-python'  # Python > 2.7.6 dreamhost not return sys.executable
BASE_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 False

sys.path.append(os.path.join(BASE_DIR))  #You must add your project here or 500

#Switch to new python

PYTHON_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'
))
