Question

在Plone 4.3.3中使用zopeskel时也会发生错误。这似乎与this question略有不同。在Plone 4.3.2下没有错误。

Answer 1

解决方法1 ：

问题似乎是缺少setuptools。安装setuptools之后，paster（以及基于它的所有工具）都可以运行生成的setup.py。以下解决了问题：

wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py -O - | sudo -u plone_buildout /usr/local/Plone-4.3.3/Python-2.7/bin/python

UnifiedInstaller-4.3.3不会安装setuptools。请参阅此ticket。

正如SteveM指出的那样（见评论），这不是推荐的解决方法。

（首选）解决方法2 ：

生成的数据存在（尽管抛出了错误！）但setup.py将无法运行。因此，不会生成Paste*目录。稍后当buildout运行时，它将生成/下载Paste*目录等。

如果要运行setup.py。您可以修补PasteScript（风险自负！）。

至于PasteScript-1.7.5转到/path/to/Plone-4.3.3/buildout-cache/eggs/PasteScript-1.7.5-py2.7.egg/paste/script/command.py的第587行并获取当前的sys.path并将其传递给subprocess.Popen()。这样setup.py将与zopeskel或paste环境一起运行。

current_env = os.environ.copy()
current_env['PYTHONPATH'] = ':'.join(sys.path)
proc = subprocess.Popen([cmd] + list(args),
                        cwd=cwd,
                        stderr=stderr_pipe,
                        stdout=subprocess.PIPE,
                        env=current_env) # <- pass the env here

我将尝试找出此解决方法可能导致问题的情况。我在PasteScript：https://bitbucket.org/ianb/pastescript/issue/16/pass-the-syspath-to-the-subprocess-in

上发布了一个问题

更新：无需生成/添加Paste* dirs（运行buildout或上面的解决方法），localcommands将无法使用。

在Plone 4.3.3上发布了“IOError：没有找到egg-info目录”
