我对 python 很陌生，我正在尝试与 census.gov API 交谈以查找几个邮政编码的人口。我能够获得我的 API 密钥，并且我正在使用这个 python 包装器：https ://github.com/datamade/census 。我能够使用 sudo easy_install pip 命令安装 pip。这是我再次运行时的输出示例：

Best match: pip 9.0.1
Processing pip-9.0.1-py2.7.egg
pip 9.0.1 is already the active version in easy-install.pth
Installing pip script to /usr/local/bin
Installing pip2.7 script to /usr/local/bin
Installing pip2 script to /usr/local/bin
Using /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg
Processing dependencies for pip
Finished processing dependencies for pip

我正在尝试使用以下命令：

pip install census
pip install us

pip install us似乎奏效了，但我在尝试时得到了回溯pip install census：

我不知道该怎么办。任何人都可以帮忙吗？顺便说一句，我正在使用 python 2.7.10。

您的用户没有对/System/Library. pip install从用户运行root或使用pip install -u将库安装到您自己的目录而不是系统目录。
