Python 安装卸载 easy_install

Question

我的 mac 上有两个版本的 python:

Apple 预装在 /usr/bin

来自 python.org 的 /Library/Frameworks/Python.framework/Versions/2.6

easy_install 总是安装到 /usr/bin 出于某些不可理解的原因

所以我现在明确地将 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 easy_install pip 和 ....:

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

• 还有一个 PYTHONPATH，我在其中保存我编写的模块

对不起，我真的不明白。

我做错了什么。

我只想在Framework Python目录下定期安装模块

根据提供的信息很难准确判断您的安装处于什么状态。 /usr/local/bin 是 Apple 提供的 /usr/bin/easy_install 的默认安装位置，因此，很可能您以某种方式调用它而不是 easy_install 应该通过运行 sh setuptools... 脚本安装。无需将 --install-dir 参数用于设置工具，也无需将 PYTHONPATH 设置为指向框架站点包目录；那是自动发生的。并且您不应该修改 PATH 变量两次，只需使用第一个 PATH 并导出即可。

从 python.org 安装程序新安装的 Python 2.6.5 和一个新的终端 session 开始，这是整个序列:
