在PyPy下安装Python鸡蛋

问题描述

如何在PyPy下安装Python egg？

在安装过程中，PyPy创建了 / usr / lib64 / pypy-1.5 / site-packages / 目录。因此，我尝试使用easy_install并将前缀设置为此目录，但是它抱怨这不是鸡蛋的有效目录。我只是从 /usr/lib/python2.7/site-packages 复制鸡蛋，还是像使用easy_install一样容易（可能在配置上有所更改）？

During installation, PyPy created /usr/lib64/pypy-1.5/site-packages/ directory. So, I tried using easy_install with prefix set to this directory, however it complains that this is not a valid directory for eggs. Do I just copy eggs from /usr/lib/python2.7/site-packages, or is it as easy as using easy_install (with some changes in configuration, perhaps)?

我的工作环境是Fedora 15 Beta，Python 2.7.1（ / usr / bin / python ），PyPy 1.5.0-alpha0和GCC 4.6.0（在 / usr / bin / pypy 中，使用yum从RPM安装），easy_install版本是：分发0.6.14（ usr / bin / easy_install ）。

My working environment is Fedora 15 Beta, Python 2.7.1 (/usr/bin/python), PyPy 1.5.0-alpha0 with GCC 4.6.0 (in /usr/bin/pypy, installed from RPM using yum), easy_install version is: distribute 0.6.14 (usr/bin/easy_install).

推荐答案

首先，您需要确保专门为PyPy安装的发行版。我不知道fedora如何打包东西，但是通常来说，为cpython安装一个软件包不会使其也可用于PyPy。特别是，/ usr / bin / easy_install可能仅适用于CPython。

First, you need to make sure that you have distribute installed specifically for PyPy. I don't know how fedora packages things, but in general installing a package for cpython does not make it available also for PyPy. In particular, /usr/bin/easy_install is probably CPython-only.

如果您使用常规安装的PyPy，则具有以下目录结构：

If you use a "normal" install of PyPy, you have this directory structure:

• /opt/pypy-1.5/
  
  
  
  • bin /
  
  
  • site-packages /
  
  
  • lib-python /
  
  
  • lib_pypy /
  
  
  • /opt/pypy-1.5/
    • bin/
    • site-packages/
    • lib-python/
    • lib_pypy/

    然后您可以下载并执行它：

    Then you can download http://python-distribute.org/distribute_setup.py and execute it:

    $ /opt/pypy-1.5/bin/pypy distribute_setup.py
    

    现在，您应该拥有/opt/pypy-1.5/bin/easy_install，它将在/opt/pypy-1.5/site-packages内安装软件包。

    Now, you should have /opt/pypy-1.5/bin/easy_install, which will install packages inside /opt/pypy-1.5/site-packages.

    但是，我不知道如何在fedora中打包pypy。它只是安装在/ usr / bin中，那么有可能安装分发版将覆盖原始cpython的/ usr / bin / easy_install。

    However, I have no clue how pypy is packaged in fedora. It it's "just" installed in /usr/bin, then there are chances that installing distribute will overwrite the original cpython's /usr/bin/easy_install.
