如何通过buildout安装readline

Question

我想将我的python项目配置为在安装过程中自动构建postgresql。你可以像下面描述的那样做：

Buildout, psycopg2, postgresql

问题是我不喜欢用

configure-options =
--without-readline

选项

这意味着我必须安装readline库。我查看了中的plone配置文件，发现了一些提示，所以我将这些部分添加到我的buildout.cfg中：

[readline-patch]
recipe = z3c.recipe.runscript
url = http://ftp.gnu.org/gnu/readline/readline-5.2-patches
install-script = ${buildout:directory}/bin/fetch-readline-patches.py:fetch
update-script = ${readline-patch:install-script}

[readline]
recipe = zc.recipe.cmmi
url = http://ftp.gnu.org/gnu/readline/readline-5.2.tar.gz
patch = ${readline-patch:prefix}/readline.patch
extra_options =
    --prefix = ${buildout:parts-directory}/opt

但是现在，我得到了这个错误：

Installing readline-patch.
While:
  Installing readline-patch.

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:
Traceback (most recent call last):

    installed_files = self[part]._call(recipe.install)

    return f()

    self.callScript(script)

    module = imp.load_source('script', filename)
IOError: [Errno 2] No such file or directory

任何帮助它工作的人都将不胜感激。

z3c.recipe.runscript没有url选项。因此脚本将不会被下载。您可以使用本地脚本，该脚本将下载并执行该文件。或者使用http://pypi.python.org/pypi/collective.recipe.scriptgen通过buildout创建一个脚本，它将通过ie curl下载文件。
