我想重定向STDERR和STDOUT一个变量.我这样做了

close(STDOUT);
close(STDERR);

my $out;
open(STDOUT, ">>", \$out);
open(STDERR, ">>", \$out);

for(1..10)
{
    print "print\n"; # this is ok. 
    warn "warn\n"; # same
    system("make"); # this is lost. neither in screen nor in variable.
}

这个问题system.我也希望捕获此调用的输出.

让我们简化一下.我的目标是使用Python中的日志记录模块在终端中进行颜色输出.我希望info有一个绿色前缀,警告有一个黄色前缀,错误有一个红色前缀.为简单起见,我们将其***用作前缀即

*** log text
*** another message with another prefix color

到目前为止我做了什么

# declaration of function (global scope)
log = None
warn = None
error = None 
def build_log_funcs():
    # why I initialize it inside the function ?
    # because script doesnt have to know about logging method
    # the function just provide log  functions
    logger = logging.getLogger(__name__)
    logger.setLevel(logging.INFO)

    sh = logging.StreamHandler()
    # LOG_FORMAT just global variable with pattern including %(levelmarks)s
    # it will be replaced …

该问题可以分为两个单独的部分。

1. 我有以下项目结构

   |- project
   |   |-- app/ - directory with actual project code
   |   |-- app.py - imports something from app/ and call create_app

   当我运行时gunicorn，我应该将他指向app实际在app.py. 所以我收到一个错误，因为gunicorn 将其视为app:app一个包。唯一的办法是重命名一些东西？

2. 我使用工厂方法来创建应用程序。所以我在 app.py 中导入create_app函数并将其传递给Managerfrom flask.ext.script。我将管理器对象传递给gunicorn。在这种情况下，gunicorn 可以正确运行，但是一旦第一个请求到来，我就会收到以下错误：

我需要一个库来处理http(c ++,c).它必须发送和接收http请求.它将在服务器中用于回答http请求.我的客户端 - 服务器交互应该使用REST模型.

我正在尝试在Linux上的Objective-C(Ubuntu)上构建hello world.main.c中

#import <Foundation/Foundation.h>

int main(void)
{

    NSLog(@"asdasd");  
    return 0;
}

我不认为这里有错误.然后我创建了Makefile:

GNUSTEP_MAKEFILES = /usr/share/GNUstep/Makefiles

include $(GNUSTEP_MAKEFILES)/common.make
TOOL_NAME = main
main_OBJC_FILES = main.m
include $(GNUSTEP_MAKEFILES)/tool.make

然后我运行"make":

This is gnustep-make 2.2.0. Type 'make print-gnustep-make-help' for help.
Making all for tool main...
make[1]: GNUmakefile: no such file or directory

我该如何解决？
