python:如何创建没有互联网连接的virtualenv

Question

我在阻止所有互联网访问的服务器上创建virtualenv时遇到问题.以前有人成功地做过吗？我搜索但没有显示任何有用的东西.我来回传输数据没有问题,但我不知道需要下载哪些软件包以及我需要安装哪些选项.

如果你对我通过尝试创建它感到好奇,这里是回溯:

netops@netops1 /spare/local/latency $virtualenv -p /usr/bin/python2.6 latency
Running virtualenv with interpreter /usr/bin/python2.6

    result = func(*args)

    return self.do_open(httplib.HTTPConnection, req)
  File "/usr/lib64/python2.6/urllib2.py", line 1156, in do_open
    raise URLError(err)
urllib2.URLError: <urlopen error [Errno 110] Connection timed out>

谢谢你的帮助.

如果您将virtualenv更新为版本> = 1.10,那么无论是否有任何标记,它都将永远不会连接到互联网(请参阅此处的"更改和新闻"部分)

Internet连接用于在虚拟环境中安装setuptools和pip包.较旧版本的virtualenv将尝试下载这两个软件包,而较新版本随附它们,并在必要时将其解压缩.

由于您的virtualenv版本(1.7.2)低于1.10,您可以使用该--never-download标志以避免连接到互联网.稍后,您可以安装(离线)所需的内容.

这里("--extra-search-dir选项"部分)解释了如何在没有互联网连接的情况下引导setuptools和pip.你基本上需要获取.egg这些包的文件并将它们放在本地的某个地方,然后你需要这样做:

$ virtualenv --extra-search-dir=/path/to/eggs --never-download ENV
