通过setup函数的参数packages、include_package_data(其实就是MANIFEST.in文件)、exclude_package_data、package_data、data_files来指定需要打包的文件。 包含的文件如下: py_modules和packages 参数指定所有 Python 源文件 package_data和data_files 参数指定所有数据文件。data_files指定安装过程中,需要安装的静态文件,如...
导入期间,如果在sys.modules找到对应的模块名的键,则取出其值,导入完成(如果值为None则抛出ModuleNotFoundError异常);否则就进行搜索操作。 sys.modules是可修改的,强制赋值None会导致下一次导入该模块抛出MoudleNotFoundError异常;如果删掉该键则会让下次导入触发搜索操作。 注意,如果要更新缓存,使用 删除sys.modules的...
