VIRTUALENV導致setuptools的錯誤

Question

我無法運行的virtualenv，我不斷收到此相同的錯誤代碼：「setuptools的PIP輪失敗，錯誤代碼1」

我看到一些網頁談論如何，這是之間的差異不同版本的setuptools，但是我已經卸載並重新安裝了幾個版本的virtualenv和setuptools，但沒有任何結果。有人知道這裏發生了什麼？

我要說的是，蟒蛇導致衝突，但更具體，它看起來彷彿蟒蛇的virtualenv中的問題。在我的MacBook上運行which virtualenv（我遇到同樣的問題）在運行linux系統時產生/Users/me/anaconda/bin/virtualenv我剛剛在收益率/usr/local/bin/virtualenv上測試了此項。

因此，在OS X上，我使用/usr/local/bin/pip install virtualenv下載了virtualenv。這不創建的virtualenv二進制文件（或者它沒有對我來說）的路徑文件夾中，所以我必須鍵入此痛苦很長的命令：

sudo /usr/local/bin/python ... {到virtualenv.py路徑系統蟒蛇的網站包文件夾} new_env

而且做到了。但這很荒謬。沒有人願意這樣做 - 即使創建鏈接仍然會在你不需要的時候破解它。

根據on this very subject的ContinuumIO GitHub的頁面，在virtualenv env和source /bin/activate命令替換爲conda create -n env python=2.7和source activate env。

在我的macbook上測試（在OS Yosemite上運行Anaconda2 v4），結果就出來了。
