点不接受自定义安装cmdclass [英] Pip not picking up a custom install cmdclass
问题描述
所以我找到了此答案 我确切的问题,但由于某种原因,它不起作用:
so I found this answer to my exact question, but for some reason it's not working:
$ cat /tmp/testinstall/setup.py
:
from setuptools.command.install import install
from setuptools import setup
class verifying_install(install):
def run(self):
print "running........"
install.run(self)
print "verifying........"
setup(name='test',
version='1',
py_modules=['test'],
include_package_data=True,
zip_safe=True,
cmdclass={'install': verifying_install}
)
但是,即使setup.py install
可以工作::
But then, even though setup.py install
works::
➜ /tmp/testinstall
$ mktmpenv && cd -
This is a temporary environment. It will be deleted when you run 'deactivate'.

(请注意running...
和verifying......
行)
pip install
不起作用:

$ deactivate && mktmpenv && cd - && pip install .

sdist的pip安装也不起作用:
And pip install of the sdist doesn't work either:

$ python setup.py sdist

请注意,这两个词均缺少running...

字.
Note the lack of running...
and verifying...
words in both of those.
有人知道这是怎么回事吗?
Anybody have any idea what's going on here?
推荐答案
我刚才遇到了这个问题.看来pip install my-package
可以转换成许多不同的命令.
I ran into this problem just now. It looks like there are many different commands that pip install my-package
can translate into.
-
setup.py install
-
setup.py egg_info
-
setup.py develop
setup.py install
setup.py egg_info
setup.py develop
因此,您需要处理所有这些不同的情况.
So you need to handle each of these different cases.
from setuptools.command.install import install
from setuptools.command.develop import develop
from setuptools.command.egg_info import egg_info
'''
BEGIN CUSTOM INSTALL COMMANDS
These classes are used to hook into setup.py's install process. Depending on the context:
$ pip install my-package
Can yield `setup.py install`, `setup.py egg_info`, or `setup.py develop`
'''
def custom_command():
import sys
if sys.platform in ['darwin', 'linux']:
os.system('./custom_command.sh')
class CustomInstallCommand(install):
def run(self):
install.run(self)
custom_command()
class CustomDevelopCommand(develop):
def run(self):
develop.run(self)
custom_command()
class CustomEggInfoCommand(egg_info):
def run(self):
egg_info.run(self)
custom_command()
'''
END CUSTOM INSTALL COMMANDS
'''
setup(
...
cmdclass={
'install': CustomInstallCommand,
'develop': CustomDevelopCommand,
'egg_info': CustomEggInfoCommand,
},
...
)
