Virtualenv: --always-copy 中的损坏 - 失败并显示：ImportError: No module named time

有趣的是（我在 Amazon Linux 上）当我执行virtualenv --always-copy app我收到此错误（ Cannot find file lib (bad symlink) ）但是当我执行mkdir app; cd app; virtualenv --always-copy .我没有。 似乎我明白为什么 - 当app由 virtualenv 创建时，它有lib64作为目录，但是当我在当前目录中创建 virtualenv 时，它变成了lib的链接

我也遇到了这个问题，但作为一种解决方法，您可以添加no-setuptools以不在您的 virtualenv 中安装 pip。 此问题与在新的 virtualenv 中安装 pip/setuptools 相关。

我的版本信息：

  • Fedora 19 x86_64，
  • Python 2.7.5的系统安装
  • 虚拟环境 1.11.4
  • 点 1.5.4

在失败和成功的情况下，第一个错误行是：

Cannot find file lib (bad symlink)

这个日志没有用，因为我没有它找不到的文件的完整路径。 因此，我破解了virtualenv.py以打印出此文件的os.path.abspath并得到：

Cannot find file /home/vagrant/lib (bad symlink)

它正在当前工作目录中寻找lib文件夹。

当前正在运行的 fix_lib64 函数中似乎存在拼写错误。 我纠正了这一点，它按预期工作。 转到行：

   1579         if symlink:                              
   1580             os.symlink('lib', lib64_link)      
   1581         else:                                    
   1582             copyfile('lib', lib64_link)

用'lib'替换lib_dir

  1579         if symlink:                              
   1580             os.symlink(lib_dir, lib64_link)

@bwilliams42 - 您的更改确实解决了符号链接逻辑的问题。 然而，当不使用 --always-copy 时，事情从根本上被打破了。 请注意，copyfile 有一个默认为 True 的“符号链接”kwarg。 下面的逻辑是有效的，如果符号链接，调用 os.symlink，否则调用 copyfile 不带“符号链接”kwarg，这导致复制文件默认 symlink=True 并且符号链接由复制文件创建。 一点用都没有。 无论如何，符号链接都是结果。

补丁不应该像下面这样吗？

   1579         if symlink:                              
   1580             os.symlink(lib_dir, lib64_link)      
   1581         else:                                    
   1582             copyfile(lib_dir, lib64_link, symlink=symlink)

我有一个问题，我这样做了，我有一个指向 /usr/lib64 的符号链接。 当 RH 更新一些 openssl 库时，这被破坏了（我使用的是 ansible），并出现一个错误，说明类似于openssl_meth function 。 我通过对 /usr/lib64 进行深拷贝来修复它。 不是一个完整的修复@bwilliams42，但为我指明了正确的方向。

顺便说一句，我正在尝试在结构的帮助下在 Vagrant 下的特殊 VM 上构建和打包我的 python 应用程序的虚拟环境，因此使用 Vagrant + centos box + 简单的结构脚本很容易重现这个错误。

我没有关于 virtualenv 应该如何工作的内部知识，所以我需要一些指导。

抱歉，我无能为力，因为我在 Windows 上，符号链接与复制（或 lib64 目录，似乎与此相关）的整个问题在那里无关。
