MAC 安装 Scrapy 报错Permission denie

今天需要爬虫安装scrapy 使用sudo sudo -s 始终报错，原因为six版本太低升级six完成安装，具体如下：「仅供参考」

Exception:

Traceback (most recent call last):

File "/Library/Python/2.7/site-packages/pip/basecommand.py", line 209, in main

status = self.run(options, args)

shutil.copyfile(srcfile, destfile)

with open(dst, 'wb') as fdst:

IOError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/six.py' #升级six版本即可原版本太低

一开始以为是没有权限经过google搜索发现是six版本问题

第一次使用：

pip install --ignore-installed six

报错权限不足

然后使用：

sudo -s pip install --ignore-installed six

搞定！

然后使用 sudo -s pip install scrapy
