python - 无法创建 virtualenv——错误的 python 路径？

Question

在尝试让 django 1.5.1 在我的笔记本电脑上运行时搞砸了一些包之后，我似乎真的搞砸了 python/pip 在我的笔记本电脑上的安装方式。我的系统上安装了 Anaconda。

我目前无法创建虚拟环境。当我运行 virtualenv ./temp-env/ 时，出现以下错误:

black-rainbows:website User$ virtualenv ./temp-env/

New python executable in ./temp-env/bin/python

  Complete output from command /Users/User/Drop.../temp-env/bin/python -c "import sys, pip; sys...d\"] + sys.argv[1:]))" setuptools pip:

我检查了我的 python 和 virtualenv 路径在哪里，它们似乎都在我的 Anaconda 路径中:

black-rainbows:website User$ which virtualenv
/Users/User/anaconda/bin/virtualenv
black-rainbows:website User$ which python
/Users/User/anaconda/bin/python

但我似乎无法弄清楚问题出在哪里，谷歌也不是特别有用。有什么建议吗？

Answer 1

which pip 您检查了which python 和which virtualenv。我还会检查 which pip。我几乎可以肯定它将与 python 位于同一位置，但我会检查(**提示:如果它最近可能已更改，请执行 hash -r)。

conda 环境 conda 有自己的虚拟环境设置。您可能已经听到了一些警告消息，警告混合和匹配 conda environment s 和 virtualenv 环境是一项有风险的业务。执行相同魔法的两个系统很可能会以糟糕的方式结束(如果不是今天，它们稍后会在一个升级时结束)。您可能只是在寻找:

conda create -n new_django python django
