安装dotenv库:pip install python-dotenv。 在项目根目录下创建.env文件,并写入环境变量,例如: TEST_VAR=TEST_VALUE fromdotenvimportdotenv_valuesimportos env_variables = dotenv_values('.env')forvarinenv_variables: os.environ[var] = env_variables[var]# 获取 NEO4J_URI,如果没有就用后面第二个参数做为...
然后,在Python代码中,我们可以使用subprocess.run来执行这个脚本,并通过env参数传递环境变量: import osimport subprocess# 加载环境变量from dotenv import load_dotenvload_dotenv()# 获取脚本的路径script_path = os.environ.get('SCRIPT_PATH', 'default/path/to/script.sh')# 使用subprocess.run执行脚本result =...

Unix或Windows中路径变量为PATH(UNIX区分大小写,Windows不区分大小写)。 在Mac OS中,安装程序过程中改变了python的安装路径。如果你需要在其他目录引用Python,你必须在path中添加Python目录。 在Unix/Linux 设置环境变量 在csh shell: 输入setenv PATH "$PATH:/usr/local/bin/python" , 按下 Enter。 在bash shell...
andit willsetall the variables to the following values. Youcan't just shove this into a shell script though, as it would just set the values for the script. You could put it in a shell script and require the user to do ". script", but that's a bit ugly.Fortunately,the target she...
