import subprocess 设置环境变量 subprocess.Popen(['MY_COMMAND', 'env', 'MY_ENV_VAR=my_value']) 3、使用ctypes模块 ctypes模块是Python的标准库之一,提供了与C兼容的数据类型,并允许调用函数在动态链接库/shared库中,我们可以使用ctypes.windll.kernel32.SetEnvironmentVariable来设置环境变量。 import ctypes 设...
通过将export TEST1=VAL1行添加到/home/username/.bashrc文件中,我定义了一个环境变量。 当在我的用户帐户的终端上使用printenv命令时,会列出此变量。但在使用以下python代码时未列出: variables = subprocess.check_output("printenv", shell=True, executable='/bin/bash').decode() 使用Python列出此变量的解决...
So try: #! /usr/bin/pythonimport subprocessvariables = subprocess.check_output("/bin/bash -c printenv", shell=True).decode()f = open("/tmp/env.txt","w")f.write("%s" % (variables))f.close() 输出不包含TEST1变量。 使用bash-l选项: #! /usr/bin/pythonimport subprocessvariables = ...

,可以通过使用Python的subprocess模块来执行Docker命令,并在命令中设置环境变量。 下面是一个示例代码,展示如何在Python cronjob中设置Docker环境变量: 代码语言:txt 复制 import subprocess def set_docker_env_variable(variable_name, variable_value): # 构建Docker命令 docker_command = f'docker run --env {varia...
下面是一个小程序(清单 6-1 ),给定一个环境、一个发行版和一个 Debian 包的文件名列表,在路径$HOME/aptly/$environment/$distribution中创建存储库,添加包,然后更新存储库的公共文件:#!/usr/bin/env python3 import json import os import os.path import subprocess import sys assert len(sys.argv) >= 4...

To temporarily disable the compilation, you could the remove above line, or edit the value to False by or take its value from an environment variable if you so choose, e.g. bool(os.getenv("USE_NUITKA", "True")). This is up to you. Or you could put it in your setup.cfg [metadat...
