使用不同的 python 安装 virtualenv 时断言错误
我的服务器有Python2.5，我想跳转到最新的Python（在我的例子中是2.7.x）。我从源代码编译了 python，下载了最新的 virtualenv (1.5.1)。
现在基本上我想做的是：
./packages/virtualenv/virtualenv.py --python=packages/Python-2.7/python env/
键入：
./packages/virtualenv/virtualenv.py
提供：
1.5.1
键入时：
packages/Python-2.7/python
提供：
Python 2.7 (r27:82500, Nov 21 2010, 23:19:15)
[GCC 4.3.2] on linux2
(cut help mesage)
>>>
但是运行 virutalenv 会导致：
AssertionError: Filename /packages/Python-2.7/Lib/os.py 不以任何这些前缀开头：['/ usr/local']
无论这意味着什么，无论我是什么，或者我没有做错。
聚苯乙烯 在构建 env + python 时，我基于问题： 如何使用自定义构建的 Python 创建 virtualenv 环境来解决此问题？
My server has Python2.5 I wanna be jump to newest Python (2.7.x in my case). I compiled python from source, I downloaded newest virtualenv (1.5.1).
Now basically what im trying to do:
./packages/virtualenv/virtualenv.py --python=packages/Python-2.7/python env/
Typing:
./packages/virtualenv/virtualenv.py
Provides:
1.5.1
While Typing:
packages/Python-2.7/python
Provides:
Python 2.7 (r27:82500, Nov 21 2010, 23:19:15)
[GCC 4.3.2] on linux2
(cut help mesage)
>>>
However runing virutalenv results in:
AssertionError: Filename /packages/Python-2.7/Lib/os.py does not start with any of these prefixes: ['/usr/local']
Whatever it means and whatever I am or I am not doing wrong.
P.S.
While building env + python I based at question: How do I work around this problem creating a virtualenv environment with a custom-build Python?

我发现这个错误可能与运行 python 的
./configure时缺少--prefix有关。所以我运行了./configure --prefix=/Path/To/Where/I/Want/Python/After/Compilation/（在我的例子中$HOME/packages/Python- 2.7），然后我输入了make，然后make install（不使用sudo- 所以 python 被安全地放入其中我告诉它是当前用户而不是 root ）。之后 virtualenv 启动并没有因AssertionError崩溃，一切都顺利进行。希望作者回答的这个问题最终能帮助别人。 :)
After reading and messing with this.
I found that this error might be related with lack of
--prefixwhile runing./configurefor python. So I've run./configure --prefix=/Path/To/Where/I/Want/Python/After/Compilation/(in my case$HOME/packages/Python-2.7), then I've typedmake, thenmake install(without usingsudo- so python was safely put into where I told it to be as current user not root). After that virtualenv initiation did not crash withAssertionErrorand everything worked like a charm.Hope that this question answered by author will eventually help someone. :)
我没有足够的代表将其添加为评论，并且这个问题已有 3 年历史，但这可能对某人有用。在 Windows 中，您必须找到 python.exe 的路径，但似乎在 Linux/OS X 中您只需路径到该文件夹。示例：
Windows：
在当前目录的子文件夹“venv”中创建虚拟环境。
I don't have enough rep to add this as a comment and this question is 3 years old, but this might be useful to someone. In Windows, you have to path out to python.exe, but it seems that in Linux/OS X you just path to the folder. Example:
Windows:
Creates a virtual environment in subfolder "venv" in current directory.

我收到错误：
我必须运行它 -
还需要从以管理员身份打开的 cmd 运行它。否则会收到错误
有人有足够的代表发表评论，请将其添加到 Mike 的 答案中作为评论。然后我会清除我的。
I don't have enough rep to add comment. Mike's answer save my day. I'm using windows.
I was getting the error :
I had to run this-
also need to run this from a cmd opened as Administrator. Otherwise getting the error
Someone with enough reps to comment please add this to Mike's answer as a comment. I'll then clear mine.
