从摊铺机任务中执行 .bat 文件

Question

如何在使用 python 模块 paver 定义的任务中执行批处理文件？我是否必须区分摊铺机任务将在什么操作系统（unix/windows）上执行？

例如项目根目录中pavement.py中定义的以下任务确实执行项目中定义的所有单元测试（使用python标准库模块unittest定义）

from paver.tasks import task
from paver.easy import sh

@task
def unit_tests():
"""
Run all unit tests.
"""
    sh('python -m unittest')

如果确实执行了

paver unit_tests

从项目根目录中的命令行。

但是我无法在 Windows 操作系统（位于项目根目录中）上执行批处理文件文件

sh('batchfile.bat')

我也无法使用 sh( ) [paver source code] 使用以下选项之一

# no call does execute the batch file (*cwd* alternatives)
sh('batchfile.bat', cwd='venv/Scripts')
sh('cmd /c batchfile.bat', cwd='venv/Scripts')

# no call does execute the batch file (*sh()* "sequential command" syntax alternatives)
sh('cd venv/Scripts; deactivate.bat')
sh('cd venv/Scripts; cmd /c deactivate.bat')

# this sequence does also not execute the batch file (absolute path alternative)
path = os.path.join(os.path.dirname(os.path.realpath(__file__)), 'venv\Scripts')
sh('deactivate.bat', cwd=path)

编辑：

我在根目录和子目录venv/Scripts/下创建了一个与“virtualenv processing”无关的批处理文件hello_world.bat：

@echo off
echo hello world
pause

打电话

paver root_dir_call

或

paver sub_dir_call

在 windows 上的项目根目录中，在 pavement.py 中添加 paver 任务，执行批处理文件，do execute the batch file with side effects 或不执行批处理文件依赖在特定的未注释 sh() 命令上：

@task
def root_dir_call():
    # use one of these two calls!
    sh('hello_world.bat') # PASS
    #sh('hello_world') # PASS

    # do not use other calls like these two because they have side effects or do not execute the batch file at all
    #sh('call hello_world.bat') # PASS (execution with side effects)
    #sh('cmd /c hello_world.bat') # PASS (execution with side effects)
    #sh('start hello_world.bat') # PASS (execution with side effects)
    #sh('cmd hello_world.bat') # FAIL (no execution, output of cmd!?)

和

@task
def sub_dir_call():
    # use one of these calls!
    sh('hello_world.bat', cwd='venv/Scripts/') # PASS
    #sh('hello_world', cwd='venv/Scripts') # PASS
    #sh('hello_world', cwd='venv\Scripts') # PASS

    # following calls do not execute the batch file
    #sh('cd venv/Scripts; hello_world.bat') # FAIL
    #sh('cd venv/Scripts/; hello_world.bat') # FAIL
    #sh('cd venv\Scripts\; hello_world.bat') # FAIL
    #sh('cd venv/Scripts; cmd /c hello_world.bat') # FAIL

当前版本的摊铺机似乎有一个bug related to the virtualenv support on windows systems see this issue。
