[英]How can I check for which command is run in setup.py?
我想知道如何根據運行哪個命令(例如install
或upload
)在setup.py中編寫一些代碼。
具體來說,我想擁有:
install
的特定文件,但沒有其他命令。 我已經嘗試閱讀distutils文檔 ,但是在細節上卻很少-distutils.command [.foo]模塊是完全沒有文檔的。
對於第一點,我可以像在此問題中提到的那樣檢查sys.argv
,但是當運行多個命令時,這是行不通的,例如:
python setup.py sdist bdist upload
因此它通常不適用。
您可以改寫命令:
from distutils.command.install import install
from distutils.core import setup
def run_file(path):
with open(path, 'r') as f:
exec(f.read())
class myinstall(install): # subclass distutils's install command
def finalize_options(self): # called after option parsing
# call base class function
install.finalize_options(self)
# super won't work because distutils under Python 2 uses old-style classes
# ignore a module
self.distribution.py_modules.remove('mymodule')
def run(self): # called to run a command
# run tests first
run_file('path/to/test.py')
# ^ remember to make sure the module is in sys.path
# run the real commands
install.run(self)
setup(
name='abc',
py_modules=['mymodule'],
cmdclass={'install': myinstall}
# ^ override the install command
)
