有时在这里指定一个版本是一个好主意,例如/usr/local/bin/python3.6。 subprocess.check_call([sys.executable,'-m','pip','wheel','--wheel-dir','my-wheels','--requirements','requirements.txt']) 我们再次用pip创建轮子。尽管很诱人,pip不能作为库使用,所以 shelling out 是唯一支持的接口。 fordistin...
A function definition is an executable statement. Its execution binds the function name in the current local namespace to a function object (a wrapper around the executable code for the function). This function object contains a reference to the current global namespace as the global namespace t...

On Unix and Mac systems if you intend to install multiple versions of Python using the same installation prefix (--prefixargument to the configure script) you must take care that your primary python executable is not overwritten by the installation of a different version. All files and directorie...
print(executable) 使用Python脚本访问CODESYS功能 CODESYS为脚本提供的所有对象和命令也在Python模块“scriptengine”中。每当启动脚本时,都会隐式导入 from scriptengine import 这样可以轻松访问CODESYS。但是,如果您的脚本导入了需要访问CODESYS API的模块,则这些模块必须自己导入scriptengine模块。
To prepare to use make, you must write a file called the makefile that describes the relationships among files in your program and provides commands for updating each file. In a program, typically, the executable file is updated from object files, which are in turn made by compiling source ...
executable python zip archives 具体内容参见下:ZlibArchive PyInstaller打包 PyInstaller中使用了两种存档。一个是ZlibArchive,它能高效地存储Python模块,并通过一些导入钩子直接导入。另一个是CArchive,类似于.zip文件,这是一种打包(或压缩)任意数据块的通用方法。
