python - venv Python 使用不正确的 sys.prefix

Question

我在 mac Mountain Lion 上运行 canopy 64 位版本:1.0.3.1262。我已经使用 easy_install 安装了 virtualenv。但是当我尝试执行命令时:

virtualenv venv --distribute

它显示以下错误:

Using base prefix '/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents'
New python executable in venv/bin/python
dyld: Library not loaded: @rpath/Python
Referenced from: /Users/xxx/Desktop/untitled folder 2/venv/bin/python
Reason: image not found
ERROR: The executable venv/bin/python is not functioning
ERROR: It thinks sys.prefix is u'/Users/xxx/Desktop/untitled folder 2' (should be u'/Users/xxx/Desktop/untitled folder 2/venv')
ERROR: virtualenv is not compatible with this system or executable 

有没有人遇到过类似的问题并解决了？预先感谢您提供宝贵的建议。

Answer 1

Canopy 使用 venv 而不是 virtualenv

尝试像这样设置您的环境:

venv -s path/to/virtual_environment_dir
