Python 安装卸载 easy_install

Question

我在我的Mac上有两个版本的Python：

一个是苹果预装的，放在 /usr/bin 目录下。

另一个是从python.org下载的，放在 /Library/Frameworks/Python.framework/Versions/2.6 目录下。

不知道为什么，easy_install总是安装到 /usr/bin 这个地方。

所以我现在明确地在这里安装easy_install：

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

现在我想用easy_install来安装pip和其他东西：

Searching for pip

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路径是：

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

• 还有一个PYTHONPATH，我把自己写的模块放在这里。

抱歉，我真的不太明白。

我到底哪里做错了？

我只是想在Framework Python目录里正常安装模块。

要卸载django这个包，

首先你需要运行这个命令：

$ easy_install -m [PACKAGE]

这个命令会把这个包的所有依赖项都删掉，然后再删除这个包的egg文件。

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

根据提供的信息，很难准确判断你的安装状态。/usr/local/bin 是苹果自带的 /usr/bin/easy_install 的默认安装位置，所以很可能你在某种情况下调用了这个，而不是通过运行 sh setuptools... 脚本应该安装的那个 easy_install。其实，使用 --install-dir 参数来设置 setuptools 是没有必要的，也不需要把 PYTHONPATH 指向框架的 site-packages 目录；这些都是自动完成的。而且，你不应该修改 PATH 变量两次，只需使用第一次的 PATH 并导出即可。

从 python.org 安装的全新 Python 2.6.5 开始，以及一个新的终端会话，下面是整个过程：
