问题
不幸的是，没有命令行参数或设置可以打开以关闭runserver中的检查。* 一般情况下 *，有--skip-checks选项可以关闭系统检查，但它们对runserver没有用处。
如果你阅读runserver命令的代码，你会看到它基本上忽略了requires_system_checks和requires_migration_checks标志，而是在其inner_run方法中显式调用self.check()和self.check_migrations()，无论如何：

def inner_run(self, *args, **options):
    [ Earlier irrelevant code omitted ...]

    self.stdout.write("Performing system checks...\n\n")
    self.check(display_num_errors=True)
    # Need to check migrations here, so can't use the
    # requires_migrations_check attribute.
    self.check_migrations()

    [ ... more code ...]

解决方案

你可以做的是派生你自己的run命令，它接受runserver命令，但覆盖执行检查的方法：

from django.core.management.commands.runserver import Command as RunServer

class Command(RunServer):

    def check(self, *args, **kwargs):
        self.stdout.write(self.style.WARNING("SKIPPING SYSTEM CHECKS!\n"))

    def check_migrations(self, *args, **kwargs):
        self.stdout.write(self.style.WARNING("SKIPPING MIGRATION CHECKS!\n"))

型
你需要把它放在<app>/management/commands/run.py下，其中<app>是任何合适的应用程序应该有这个命令。然后你可以用./manage.py run调用它，你会得到这样的东西：

Performing system checks...

SKIPPING SYSTEM CHECKS!

SKIPPING MIGRATION CHECKS!

Django version 1.10.2, using settings 'foo.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

有一件事可能会加快PyCharm的调试器，那就是关闭“Collect run-time types information for code insight”设置：位于File > Settings > Build，Execution，Deployment > Python调试器下。

我没有足够的声誉来评论Louis' answer，但是从django 4.0开始，runserver命令不再显式调用self.check()。它现在基于--skip-checks选项有条件地运行。

def inner_run(self, *args, **options):
        [ Earlier irrelevant code omitted ...]

        if not options["skip_checks"]:
            self.stdout.write("Performing system checks...\n\n")
            self.check(display_num_errors=True)
        # Need to check migrations here, so can't use the
        # requires_migrations_check attribute.
        self.check_migrations()

         [ ... more code ...]

换句话说，python manage.py runserver --skip-checks将跳过系统检查。
