无法在 Dropbox 文件夹中执行 heroku 的 Python 教程
EDIT2:好吧,这很奇怪。 (我无法回答我自己的问题,所以我只是将其作为对问题的另一个编辑。我认为这与我尝试在 Dropbox 同步目录中进行此安装有关。我得到了这个任何人都可以解释为什么会出现这种情况吗?
原始问题:
我正在尝试在我的 Mac OS X (Lion) 上进行 Heroku 的 Python 设置教程 (http://devcenter.heroku.com/articles/python)。 ),但我赶上了这一步创建 virtualenv 的
方法是在命令行中执行此操作(不使用 sudo 导致权限错误):
sudo pip install virtualenv
但是,当我执行“virtualenv venv --distribute”(我也尝试使用 sudo)时,出现以下错误:
New python executable in venv/bin/python
Installing distribute..............................................................................................................................................................................................................................................................................................done.
Installing pip...
Error [Errno 2] No such file or directory while executing command /Users/AndyFang/Drop...env/bin/easy_install /Library/Python/2.7/...pport/pip-1.1.tar.gz
...Installing pip...done.
Traceback (most recent call last):

不太确定该怎么做。我的 Mac 上似乎没有 easy_install,但我确实有它......我不确定这是怎么回事?
编辑:我也尝试使用 easy_install 安装 virtualenv,但我得到完全相同的错误。
EDIT2: OK this is weird. (I can't answer my own question, so I just put it as another edit to the question. I think it has something to do with the fact that I tried to do this installation within a Dropbox-synced directory. I got this to work on my Desktop. Can anyone explain why this is the case?
Original question:
I'm trying to do Heroku's Python setup tutorial (http://devcenter.heroku.com/articles/python), on my Mac OS X (Lion), but I get caught up with the step of creating a virtualenv.
So what I did was this in the command line (not using sudo caused permissions error):
sudo pip install virtualenv
But then, when I do "virtualenv venv --distribute" (I also tried with sudo), I get the following error:
New python executable in venv/bin/python
Installing distribute..............................................................................................................................................................................................................................................................................................done.
Installing pip...
Error [Errno 2] No such file or directory while executing command /Users/AndyFang/Drop...env/bin/easy_install /Library/Python/2.7/...pport/pip-1.1.tar.gz
...Installing pip...done.
Traceback (most recent call last):
File "/usr/local/bin/virtualenv", line 8, in <module>
load_entry_point('virtualenv==1.7.1.2', 'console_scripts', 'virtualenv')()

raise child_exception
OSError: [Errno 2] No such file or directory
Not really sure what to do. It seemed like I didn't have easy_install on my Mac, but I do have it... I'm not sure what the deal is?
EDIT: I also just tried installing virtualenv with easy_install, but I get the exact same error.

如果您的问题与我的相同,那么这是因为 Dropbox 同步文件夹的路径中存在空格。
If your problem is the same as mine, then it's because there's a space somewhere in the path to your Dropbox-synced folder.
Virtualenv 不可移植,因此如果路径不匹配,则无法在多台计算机上保持它们同步。
一般来说,这是一个坏主意:)
Virtualenvs aren't portable, so you can't keep them synced across multiple machines if the paths don't match up.
In general, it's a bad idea :)
