【问题描述】：

我尝试在我的 mac os x 1.8.5 中安装 scrapy，但非常困难。

我尝试使用页面说明安装de“简单工具”（不容易;））：

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

和命令：

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

但总是出错：

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.

我试过用 root 用户删除目录，但总是：

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”参数应用于该指令？在我的 mac 中安装 scrapy 的一些解决方案？

你能帮帮我吗？

非常感谢！！！

【解决方案1】：

需要注意的是，这将在系统上安装除 scrapy 之外的其他一些软件包，我建议安装 homebrew，然后 pip，然后从中进行 scrapy。命令顺序是

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http://brew.sh/、https://pypi.python.org/pypi/pip 上找到有关这些软件包的更多信息。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 会使用它安装 pip，但以防万一，您可以显式安装它。

【解决方案2】：

就像idea of Akshat，但在我的情况下，我使用sudo 来安装带有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写入权限，如错误日志中所述。
