Python安装、卸载和easy_install

Question

我在我的Mac上安装了两个版本的Python：

一个是由Apple预装在/usr/bin目录下的；

另一个是从python.org下载并安装在/Library/Frameworks/Python.framework/Versions/2.6目录下的。

但是，由于某种难以理解的原因，easy_install总是安装在/usr/bin目录下。

因此，我现在明确地将easy_install安装在：

sh setuptools-0.6c11-py2.6.egg --install-dir=/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages

现在我想要使用 easy_install 安装 pip，然后......

Searching for pip
Best match: pip 0.8
Processing pip-0.8-py2.6.egg
pip 0.8 is already the active version in easy-install.pth
Installing pip script to /usr/local/bin
error: /usr/local/bin/pip: Permission denied

我的路径和Python路径：

PATH="/Library/Frameworks/Python.framework/Versions/2.6/bin:${PATH}"
export PATH

PATH="/Library/Frameworks/Python.framework/Versions/Current/bin:${PATH}"
export PATH

PYTHONPATH="/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages"
export PYTHONPATH

• 我还有一个PYTHONPATH，用来存放我编写的模块

抱歉，我真的不明白。

我做错了什么。

我只是想在框架Python目录中正常安装模块。

Answer 1

根据提供的信息，很难确定您的安装状态。 /usr/local/bin 是Apple提供的/usr/bin/easy_install的默认安装位置，因此最可能的情况是，您在调用该程序而不是通过运行sh setuptools...脚本安装的easy_install。无需使用--install-dir参数安装setuptools，也不需要设置PYTHONPATH指向框架站点包目录；这些都会自动发生。您不应该两次修改PATH变量，只需使用第一个PATH并导出即可。

从新安装的Python 2.6.5（来自python.org安装程序）和新的终端会话开始，以下是整个序列：

再次感谢！我从您上次的回答中学到了很多！我如何重新获得一个干净的刀片？我如何卸载所有东西？Sitepackages 和 Python？这样就不会留下任何可能出错的东西了！ - MacPython

1. 如何将命令：sh setuptools-0.6c11-py2.6.egg安装到Framework而不是usr/bin。如果我执行完全相同的操作，它会写入usr/bin。
2. which easy_install: 感谢这个生命！！！

- MacPython

删除python.org 2.6以重新开始： sudo rm -r /Library/Frameworks/Python.framework/Versions/2.6 这是一行。请仔细输入！sh setuptools...脚本使用在您的shell PATH中首先找到的任何python2.6命令。那应该是框架bin目录中的命令。 - Ned Deily

Answer 2

卸载django包。

首先，您需要运行此命令：

$ easy_install -m [PACKAGE]

该命令将删除该包的所有依赖项。然后删除该包的egg文件。

$ rm -rf .../python2.X/site-packages/[PACKAGE].egg
