运行python脚本时如何抑制警告？

我正试图抑制警告

这是我的esri python版本

python-V

Python 2.7.16

我试过这个

python.exe-W ignore GET_ESRIGIS_WEB_TOKEN.py

但它给出了这个错误

无效-忽略W选项：无效操作：““忽略”

我做错了什么

ps：这是帮助（请参阅下面的-W选项）

-W参数：警告控制；参数是操作：消息：类别：模块：线路号 另外，PYTHONWARNINGS=arg

usage: python.exe [option] ... [-c cmd | -m mod | file | -] [arg] ... Options and arguments (and corresponding environment variables): -b : issue warnings about comparing bytearray with unicode (-bb: issue errors) -B : don't write .py[co] files on import; also PYTHONDONTWRITEBYTECODE=x -c cmd : program passed in as string (terminates option list) -d : debug output from parser; also PYTHONDEBUG=x -E : ignore PYTHON* environment variables (such as PYTHONPATH) -h : print this help message and exit (also --help) -i : inspect interactively after running script; forces a prompt even if stdin does not appear to be a terminal; also PYTHONINSPECT=x -m mod : run library module as a script (terminates option list) -O : optimize generated bytecode slightly; also PYTHONOPTIMIZE=x -OO : remove doc-strings in addition to the -O optimizations -R : use a pseudo-random salt to make hash() values of various types be unpredictable between separate invocations of the interpreter, as a defense against denial-of-service attacks -Q arg : division options: -Qold (default), -Qwarn, -Qwarnall, -Qnew -s : don't add user site directory to sys.path; also PYTHONNOUSERSITE -S : don't imply 'import site' on initialization -t : issue warnings about inconsistent tab usage (-tt: issue errors) -u : unbuffered binary stdout and stderr; also PYTHONUNBUFFERED=x see man page for details on internal buffering relating to '-u' -v : verbose (trace import statements); also PYTHONVERBOSE=x can be supplied multiple times to increase verbosity -V : print the Python version number and exit (also --version) -W arg : warning control; arg is action:message:category:module:lineno also PYTHONWARNINGS=arg -x : skip first line of source, allowing use of non-Unix forms of #!cmd -3 : warn about Python 3.x incompatibilities that 2to3 cannot trivially fix file : program read from script file - : program read from stdin (default; interactive mode if a tty) arg ...: arguments passed to program in sys.argv[1:] 用法：python.exe[选项]…[-c cmd |-m mod | file |-][arg]。。。 选项和参数（以及相应的环境变量）： -b:发出有关将bytearray与unicode进行比较的警告 （-bb：问题错误） -B：不要在导入时写入.py[co]文件；还有pythontwritebytecode=x -c cmd：作为字符串传入的程序（终止选项列表） -d：从解析器调试输出；也可以是PYTHONDEBUG=x -E:忽略PYTHON*环境变量（例如PYTHONPATH） -h：打印此帮助消息并退出（也可以是--help） -i：在运行脚本后以交互方式进行检查；强制执行提示 如果stdin似乎不是终端，则PYTHONINSPECT=x -m mod：以脚本形式运行库模块（终止选项列表） -O：稍微优化生成的字节码；同时PYTHONOPTIMIZE=x -OO：除了-O优化之外，还要删除文档字符串 -R：使用伪随机salt使各种类型的hash（）值 在解释器的不同调用之间不可预测，如 针对拒绝服务攻击的防御 -Q arg：分区选项：-Qold（默认），-Qwarn，-Qwarnall，-Qnew -s：不要将用户站点目录添加到sys.path；还要添加PYTHONNOUSERSITE -S：不要在初始化时暗示“导入站点” -t:发出有关选项卡使用不一致的警告（-tt:发出错误） -u：无缓冲二进制标准输出和标准输出；也是pythonunbuffer=x 有关'-u'的内部缓冲的详细信息，请参见手册页 -v:verbose（跟踪导入语句）；也可以是PYTHONVERBOSE=x 可以多次提供以增加详细性 -V：打印Python版本号并退出（也是--version） -W参数：警告控制；参数为操作：消息：类别：模块：线路号 还有PYTHONWARNINGS=arg -x：跳过源代码的第一行，允许使用非Unix形式的#！cmd -3：警告2to3无法解决的Python 3.x不兼容问题 文件：从脚本文件读取的程序 -：从stdin读取的程序（默认；如果是tty，则为交互式模式） arg…：在sys.argv[1:]中传递给程序的参数

通常

python-W ignore file.py应该可以工作

但是，您也可以尝试将其添加到代码中以抑制所有警告

导入警告
警告。过滤器警告（“忽略”）

参考：

这很奇怪。
-W ignore
是正确的方法。如果可以安慰的话，它可以在我的python2 linux安装上运行！你有没有可能得到错误的
警告
模块？编写一个小脚本，导入并打印
警告。uu文件u
。你有
PYTHONWARNINGS
环境变量？嗯aps格式错误。也许这个“esri”python构建有些奇怪…不管是什么。这是一个课程作业吗？也许他们在构建中禁用了它？
