例如Windows和DOS操作系统中的path环境变量。 当要求系统运行一个程序而没有告诉它程序所在的完整路径时,系统除了在当前目录下面寻找此程序外,还应到path中指定的路径去找。 用户通过设置环境变量,来更好的运行进程。 DWORD GetEnvironmentVariable(LPCSTR lpName, LPSTR lpBuffer, DWORD dSize) lpName是要求查询的环...

我知道用GetEnvironmentVariable("environmentVariableKeyHere").核获取环境变量,理论上使用的库是用.NET方法的System.Environment但是,在Linux (Ubuntu18.04)上,这并没有获取基于用户的环境变量。我甚至使用了GetEnvironmentVariables()方法,并查看了它获取的整个列表。该列表中没有/所在的任何用户环境变量。它是用Rider ...
sudoapt-getinstallpython3-venv 1. 创建一个新的虚拟环境: python3-mvenv myenv 1. 激活虚拟环境: sourcemyenv/bin/activate 1. 在此环境中安装所需包,例如,使用 pip 安装 Flask: pipinstallFlask 1. 当完成开发后,可以使用deactivate命令退出虚拟环境。
