Question

我创建了一个自定义贴纸命令，如http://pythonpaste.org/script/developer.html#what-do-commands-look-like中所述。在我的setup.py中，我已经定义了这样的入口点：

entry_points={
  'paste.global_paster_command' : [
    'xxx_new = xxxconf.main:NewXxx'
  ]
}

我在激活的virtualenv中并通过

安装了我的包

python setup.py develop

如果我在我的包文件夹中运行paster，我会看到我的自定义命令，我可以通过paster xxx ...运行它。但如果我离开我的包文件夹paster不再显示我的命令。我检查了which paster，这是我的virtualenv的版本。我还启动了一个python解释器并导入xxxconf，它工作正常。

当我在我的包文件夹之外时，我不知道为什么我的全局命令无法识别！

你做错了什么，应该有用。这是最小的工作示例，您可以使用virtualenv进行测试：

blah/setup.py：

from setuptools import setup, find_packages

setup(name='blah',
      version='0.1',
      packages=find_packages(exclude=['ez_setup', 'examples', 'tests']),
      include_package_data=True,
      zip_safe=False,
      entry_points={'paste.global_paster_command': [ "xxx_new = blah.xxx:NewXxx", ] },
      )

blah/blah/xxx.py：

from paste.script import command

class NewXxx(command.Command):
    usage = "PREFIX"
    summary = "some command"
    group_name = "my group"

blah/blah/__init__.py：空。

现在测试：

$ pwd
/tmp
$ virtualenv paster
New python executable in paster/bin/python
Installing setuptools............done.
Installing pip...............done.
$ . paster/bin/activate

您应该在活动的virtualenv中安装paster_script。然后你可以在任何地方使用它。

在virtualenv中找不到全局贴纸命令
