我正在开发一台运行 10.6 Snow Leopard 的 iMac（受 IT 政策的限制）。我反复尝试安装pip（作为安装的前兆，csvkit但对以下错误消息感到困惑：
smg-02639:~ matmo$ pip install csvkit
Usage: pip COMMAND [OPTIONS]
pip: error: No command by the name pip install
(maybe you meant "pip install csvkit")
这应该足以解释我为什么感到委屈。我发现了一个类似但最终不相关的问题。我在做什么错？
为了可能不必要的完整性，这里是安装顺序：
smg-02639:~ matmo$ sudo easy_install pip
Searching for pip
Best match: pip 1.1
Adding pip 1.1 to easy-install.pth file
Installing pip script to /usr/local/bin
Installing pip-2.6 script to /usr/local/bin
Using /Library/Python/2.6/site-packages
Processing dependencies for pip
Finished processing dependencies for pip
smg-02639:~ matmo$ pip help
Usage: pip COMMAND [OPTIONS]
pip: error: No command by the name pip help
(maybe you meant "pip help")
