I had the same issue, and solved it simply by removing the old env file with <code>rm -rf env</code>. Then I created a new environment with <code>virtualenv env</code>, followed by installing the requirements, normally <code>pip install -r requirements.txt</code>, then I was able to run my app successfully.

blocks|key|4480015|text|这个错误是因为你启动了一个新的进程，在我的例子中，django项目的虚拟环境是一个拷贝，当它们变得很多时，你会得到这个错误。只要删除旧的环境并创建一个新的环境。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4480016|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This error is occurs 'cause time you start a new process, in my case virtual environment for django project one copy is made and when they becomes to many you get this error.
Just remove the old env and create a new environment.

blocks|key|4480958|text|我可以隐约推测这是因为你有一个虚拟环境指向它自己。我可以进一步模糊地推测，如果您尝试创建一个虚拟环境，但不知何故决定在不运行deactivate的情况下再次创建，就会发生这种情况。然后，您可以通过符号链接使virtualenv中的python+(有效地)指向同一virtualenv中的...+python。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4480959|由于这是一种推测，我希望真正有这个问题的人可以确认或否认这是发生的事情。|4480960|无论如何，如果是这样的话，这里的其他答案说删除环境并重新开始基本上是正确的，但请记住首先使用deactivate。|4480961|entityMap^0|1Q|A|37|6|43|6|0|0|1A|A|0^^$0|@$1|2|3|4|5|6|7|L|8|@$9|M|A|N|B|C]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|S|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|T|8|@$9|U|A|V|B|C]]|D|@]|E|$]]|$1|J|3|-4|5|6|7|W|8|@]|D|@]|E|$]]]|K|$]]

I can vaguely speculate that the reason for this is that you have a virtualenv pointing to itself. I can further vaguely speculate that this would happen if you attempt to create a virtualenv, but then somehow decide to do it again without running <code>deactivate</code>. Then you have <code>python</code> in the virtualenv pointing back to ... <code>python</code> in (effectively) the same virtualenv by a symbolic link.

Since this is speculative, I hope someone who actually has this problem can confirm or deny that this is what happened.

Anyway, if this is the case, the other answers here saying remove the env and start over are basically correct, but remember to <code>deactivate</code> first.

When I tried to install Tensorflow by Virtualenv, I confronted this question too. I just removed the old env, then built a new env. It works. 

When I type <code>which pip</code>, it returns <code>/Users/xiang/tensorflow/bin/pip</code>. Which is exactly the path in the new env I built.

I had this. In my case I am not sure what happened but my python2 had been replaced by a link so I had:

<pre><code>ls -l
lrwxrwxrwx 1 &lt;me&gt; staff 7 Oct 23 14:04 python -&gt; python2
lrwxrwxrwx 1 &lt;me&gt; staff 6 Nov 6 14:28 python2 -&gt; python
lrwxrwxrwx 1 &lt;me&gt; staff 7 Oct 23 14:04 python2.7 -&gt; python2
</code></pre>

The middle link is wrong, this is a circual reference, it should be the executable (had another venv to look at already). I deleted python2 and copied the actual file (in my case /bin/python2.7) to there:

<pre><code>rm python2
cp /bin/python2.7 python2
ls -l
lrwxrwxrwx 1 &lt;me&gt; staff 7 Oct 23 14:04 python -&gt; python2
-rwxr-xr-x 1 &lt;me&gt; staff 7216 Dec 6 14:57 python2
lrwxrwxrwx 1 &lt;me&gt; staff 7 Oct 23 14:04 python2.7 -&gt; python2
</code></pre>

(NOTE: I can't speak for every distro. you'll need to work out your own version. Try this:

<pre><code>ls -l `which python`
</code></pre>

and if that is a link follow it until you get to the actual executable. For me is was /bin/python -> python2 -> python2.7. Ergo I copied /bin/python2.7)

I am trying to install numpy in a virtual environment that I created. I used the following series of commands to create and activate and then installing a local version of numpy (all these after cd-ing into the project folder).

<pre><code>virtualenv venv
source venv/bin/activate
pip install numpy
</code></pre>

However, after the last command, I get this error: 

<pre><code>bash: /home/fieldsofgold/Desktop/test/venv/bin/pip: /home/fieldsofgold/Desktop/test/venv/bin/python: bad interpreter: Too many levels of symbolic links
</code></pre>

Could anyone please help me solve it and let me know what could be going wrong?

I am using Ubuntu 14.04 in VirtualBox, and the python version is 2.7.6.
