It looks like you don't have the permission to write to the Python's site-package:

Permission denied: '/Library/Python/2.7/site-packages/easy-install.pth'

A good practice is to setup a virtual environment. Alternatively run the installation as superuser - by using sudo for example.

[desireYY]

看起来您没有写入 Python 的 site-package 的权限：

权限被拒绝：'/ Library /Python/2.7/site-packages/easy-install.pth'

一个好的做法是设置虚拟环境。或者以超级用户身份运行安装 - 例如使用 sudo。

i use sudo ,but still can't setup

[desireYY]

when i use pip steup, still fail

[fbochu]

It seem to be a similar issue that #21. In your logs, we see that package zbarlight produced metadata for project name unknwon which is a sign that our setuptools version is too old (zbarligth is only compatible with setuptools 30.3+).

[fbochu]

I close this problem as a duplicate of # 21. Be free to reopen it if it is not the case.
