我也遇到了同样的问题。似乎以某种方式触发setuptools进行“旧式安装”
distutils，但确实不支持
install_requires。
您可以在setuptools / setuptools / command /
install.py，第51-74行中调用install.run（self），后者会调用run（self）
https://bitbucket.org/pypa/setuptools/src/8e8c50925f18eafb7e66fe020aa91a85b9a4b122/setuptools/command/install.py?at=default
def run(self): # Explicit request for old-style install? Just do it if self.old_and_unmanageable or self.single_version_externally_managed: return _install.run(self) # Attempt to detect whether we were called from setup() or by another # command. If we were called by setup(), our caller will be the # 'run_command' method in 'distutils.dist', and *its* caller will be # the 'run_commands' method. If we were called any other way, our # immediate caller *might* be 'run_command', but it won't have been # called by 'run_commands'. This is slightly kludgy, but seems to # work. # caller = sys._getframe(2) caller_module = caller.f_globals.get('__name__','') caller_name = caller.f_pre.co_name if caller_module != 'distutils.dist' or caller_name!='run_commands': # We weren't called from the command line or setup(), so we # should run in backward-compatibility mode to support bdist_* # commands. _install.run(self) else: self.do_egg_install()我不确定这种行为是否有意，但是要替换
install.run(self)
与
install.do_egg_install()
应该可以解决您的问题。至少它对我有用，但是我也希望得到更详细的答案。谢谢！
