許可被拒絕pip virtualenv

Question

我一直試圖設置virtualenv用於django，但我一直有問題用pip安裝virtualenv。

jeff@jeff-HP-MacBook-Android:~/repos$ pip install virtualenv
Collecting virtualenv
  Using cached virtualenv-13.1.2-py2.py3-none-any.whl
Installing collected packages: virtualenv
Exception:

我能找到的最接近的答案是關於virtualenv中的權限： 如何在與virtualenv一起使用pip時避免“權限被拒絕”

但是我可以告訴我的問題是我的pip安裝有問題，因為我顯然還沒有使用virtualenv。

Answer 1

我不認為你的pip安裝有什么問題。 virtualenv本身就是一個Python模塊，默認情況下它位於/usr/local/lib/python2.7/dist-packages中，這是一個用戶沒有寫入權限的文件夾。 如果您有sudo訪問權限，那么最簡單的方法是嘗試：

sudo pip install virtualenv

一旦你完成了，你應該能夠創建virtualenvs而無需使用sudo。 或者，這里有說明來制作您自己的虛擬環境，但看起來您可能需要對指導您下載的腳本進行一些手動編輯。
