如何在 Mac OS X 上为 Python 3 安装 pip? [英] How to install pip for Python 3 on Mac OS X?

问题描述

OS X (Mavericks) 安装了 Python 2.7 stock.但是我用 3.3 做我自己的所有个人 Python 东西.我刚刚刷新了我的 3.3.2 安装并安装了新的 3.3.3.所以我需要再次安装 pyserial.我可以像以前那样做，那就是:

OS X (Mavericks) has Python 2.7 stock installed. But I do all my own personal Python stuff with 3.3. I just flushed my 3.3.2 install and installed the new 3.3.3. So I need to install pyserial again. I can do it the way I've done it before, which is:

1. 从pypi下载pyserial
2. 解压 pyserial.tgz
3. cd pyserial
4. python3 setup.py install

但我想像那些酷孩子一样做，比如pip3 install pyserial.但目前尚不清楚我是如何做到这一点的.而就在这一点上.对 virtualenv 不感兴趣(除非我必须).

But I'd like to do like the cool kids do, and just do something like pip3 install pyserial. But it's not clear how I get to that point. And just that point. Not interested (unless I have to be) in virtualenv yet.

推荐答案

更新:Python3.4 不再需要这样做.它安装 pip3 作为库存安装的一部分.

UPDATE: This is no longer necessary with Python3.4. It installs pip3 as part of the stock install.

我最终在 python 邮件列表上发布了同样的问题，并得到了以下答案:

I ended up posting this same question on the python mailing list, and got the following answer:

# download and install setuptools
curl -O https://bootstrap.pypa.io/ez_setup.py
python3 ez_setup.py
# download and install pip
curl -O https://bootstrap.pypa.io/get-pip.py
python3 get-pip.py

这完美地解决了我的问题.在为我自己添加以下内容后:

Which solved my question perfectly. After adding the following for my own:

cd /usr/local/bin
ln -s ../../../Library/Frameworks/Python.framework/Versions/3.3/bin/pip pip

为了可以直接运行 pip，我能够:

So that I could run pip directly, I was able to:

# use pip to install
pip install pyserial

或:

# Don't want it?
pip uninstall pyserial
