Python Fabric 错误

Question

我正在使用fabric（把Django部署到apache上），一切看起来都挺顺利，直到我开始安装网站的任务：

def install_site():
    "Add the virtualhost file to apache"
    require('release', provided_by=[deploy, setup])
    sudo('cd %(path)/releases/%(release)/%(release); cp %(project_name)/%(virtualhost_path)/%(project_domain) /etc/apache2/sites-available/%(project_domain)s')
    sudo('cd /etc/apache2/sites-available; a2ensite %(project_domain)') 

但是我一直遇到这个错误：

[173.203.124.16] sudo: cd %(path)/releases/%(release)/%(release);
[173.203.124.16] err: /bin/bash: -c: line 0: syntax error near unexpected token
`('
[173.203.124.16] err: /bin/bash: -c: line 0: `cd %(path)/releases/%(release)/%(r
elease);'

Warning: sudo() encountered an error (return code 2) while executing 'cd %(path)
/releases/%(release)/%(release);'

我反复检查了fabfile.py，但就是找不到错误的原因……有没有什么想法？

Answer 1

问题解决了，我注意到使用“hg archive ..”这个命令时，它会把仓库压缩成两层结构。

local('hg archive --type=tgz %(release)s.tar.gz' % {'release': env.release})

结果生成了一个名为20100418105144.tar.gz的文件，打开后里面的结构是这样的：

20100418105144.tar.gz
/20100418105144
/repo

你可以试试使用cd上下文管理器。你可能还在处理你的字符串插值时遇到问题。

def install_site():
    # Add the virtualhost file to apache
    require('release', provided_by=[deploy, setup])

    with cd('%s/releases/%s/%s' % (path, release, release)):
        sudo('cp %s/%s/%s /etc/apache2/sites-available/%s' % (project_name, virtualhost_path, project_domain, project_domain))

    with cd('/etc/apache2/sites-available'):
        sudo('a2ensite %s' % project_domain)

Answer 3

def install_site():
    "Add the virtualhost file to apache"
    require('release', provided_by=[deploy, setup])

    with cd('%(path)s/releases/%(release)s/%(release)s' % env):
        sudo('cp %(project_name)s/%(virtualhost_path)s/%(project_domain)s '
                 '/etc/apache2/sites-available/%(project_domain)s' % env)
    with cd('/etc/apache2/sites-available'):
         sudo('a2ensite %(project_domain)s' % env) 

当然可以！请把你想要翻译的内容发给我，我会帮你把它变得更简单易懂。
