我正在尝试安装一个名为Scrapy的模块。我用它安装了它
pip install Scrapy
我在/usr/local/lib/python2.7/site-packages中看到了'scrapy'文件夹,但是当我尝试在Python程序中导入它时,表示没有该名称的模块。关于为什么会发生这种情况的任何想法?
编辑:这是pip命令的输出:

Cleaning up...
当我运行/ usr / local / bin / scrapy时,我得到了命令和可用命令的用法。我注意到我的/ usr / local / bin中有一个python2.7和python2.7-32,我记得因为Mavericks的问题而安装32位版本。
这是输出 python /usr/local/bin/scrapy
:
Traceback (most recent call last): File "/usr/local/bin/scrapy", line 3, in <module> from scrapy.cmdline import execute ImportError: No module named scrapy.cmdline
和 head /usr/local/bin/scrapy
