你们在 el capitan 运行上 scrapy 了吗？

[gavin6liu]

安装的时候说 six 不对，发现苹果已经预装了 six ，就忽略 six ，安装成功后，运行 scrapy ，说 six 有问题。系统又不让卸载预装的 six ，这个局如何解？

[gavin6liu]

pip uninstall six
```
OSError: [Errno 1] Operation not permitted: '/var/folders/fg/rzz7b0b57bb0vz79t903yqc00000gn/T/pip-lhVUMQ-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six-1.4.1-py2.7.egg-info'
```

虚拟环境

[limbo0]

ls 正解, 不过 el 系统没有遇到这个错误

[patrickstar]

用 Anaconda 吧，安装都相当简单，也支持 pip 安装和虚拟环境等。

用系统自带 Python / Ruby 还往全局装包就是作大死。推荐 homebrew 。

[gavin6liu]

@aisk 是用 brew 重新装个 python 吗？

[gavin6liu]

@yishenggudou thinks~~ 初学 python ，新技能 get

[aisk]

@gavin6liu 嗯。
