Question

我在运行virtualenv时遇到问题，并且我一直收到同样的错误代码：“setuptools pip wheel失败，错误代码为1”

我看到一些页面讨论了不同版本的setuptools之间的差异，但是我已经卸载并重新安装了几个版本的virtualenv和setuptools而没有结果。有谁知道这里发生了什么？

我会说Anaconda会引发冲突，但更具体地说，似乎Anaconda的virtualenv就是问题所在。在我的macbook上运行which virtualenv（我遇到同样的问题）在Linux系统上运行它时会产生/Users/me/anaconda/bin/virtualenv我刚刚测试了这个产生/usr/local/bin/virtualenv。

因此，在OS X上，我使用/usr/local/bin/pip install virtualenv下载了virtualenv。这不会在PATH文件夹中创建virtualenv二进制文件（或者它对我来说没有），所以我不得不键入这个痛苦的长命令：

sudo /usr/local/bin/python ... {系统python＆site-packages文件夹中virtualenv.py的路径} new_env

就是这样做的。但这太荒谬了。没有人愿意这样做 - 即使创建链接仍然会在你不需要时进行黑客攻击。

根据ContinuumIO github页面on this very subject，virtualenv env和source /bin/activate命令将替换为conda create -n env python=2.7和source activate env。

在我的Macbook上测试（在Yosemite OS上运行Anaconda2 v4）并且它已经完成了。

Virtualenv导致setuptools错误
