Python 安装scrapy mac 2.7

我尝试在mac os x 1.8.5中安装scrapy，但非常困难

我尝试按照页面说明安装de“easy tools”（不容易；）：

https://pypi.python.org/pypi/setuptools

和命令：

curl https://bootstrap.pypa.io/ez_setup.py -o - | python

但总是错误：

iMac-de-ERIKA:~ root$ curl bootstrap.pypa.io/ez_setup.py -o - | python

Checking .pth file support in /Library/Python/2.7/site-packages/
error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/test-easy-install-725.pth'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /Library/Python/2.7/site-packages/

Perhaps your account does not have write access to this directory?  If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account.  If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.

For information on other options, you may wish to consult the
documentation at:

  pythonhosted.org/setuptools/easy_install.html

Please make the appropriate changes for your system and try again.

Something went wrong during the installation.
See the error message above.

我已尝试使用root用户删除目录，但始终：

iMac-de-ERIKA:~ root$ sudo rm -rf /Library/Python/2.7/site-packages
rm: /Library/Python/2.7/site-packages/README: Permission denied
rm: /Library/Python/2.7/site-packages: Permission denied

如何将“-install dir”参数应用于此指令？ 在我的mac上安装scrapy的一些解决方案

你能帮我吗

非常感谢

有一点需要注意，这将在系统上安装除scrapy之外的其他一些软件包，我建议先安装自制软件，然后安装pip，然后再安装scrapy。 命令顺序如下：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew install python
brew install pip
pip install scrapy

您可以分别在上找到有关包的更多信息。 基本上，brew是mac os x的包管理器，而pip是python的包管理器。从brew安装python会安装pip，但为了以防万一，您可以显式安装它。

就像我的例子一样，我使用

sudo

安装带有

pip

的python包，包括Scrapy。如果您是Mac的管理员，请尝试使用

sudo

执行上述命令，以获得错误日志中所述的写访问权限
