许可被拒绝pip virtualenv

Question

我一直试图设置virtualenv用于django，但我一直有问题用pip安装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

我能找到的最接近的答案是关于virtualenv中的权限： 如何在与virtualenv一起使用pip时避免“权限被拒绝”

但是我可以告诉我的问题是我的pip安装有问题，因为我显然还没有使用virtualenv。

Answer 1

我不认为你的pip安装有什么问题。 virtualenv本身就是一个Python模块，默认情况下它位于/usr/local/lib/python2.7/dist-packages中，这是一个用户没有写入权限的文件夹。 如果您有sudo访问权限，那么最简单的方法是尝试：

sudo pip install virtualenv

一旦你完成了，你应该能够创建virtualenvs而无需使用sudo。 或者，这里有说明来制作您自己的虚拟环境，但看起来您可能需要对指导您下载的脚本进行一些手动编辑。
