成功解决ModuleNotFoundError: No module named codecs

""" Standard "encodings" Package

    Standard Python encoding modules are stored in this package directory.

    Codec modules must have names corresponding to normalized encoding names as defined in the normalize_encoding() function below, e.g. 'utf-8' must be implemented by the module 'utf_8.py'.
    Each codec module must export the following interface:

    * getregentry() -> codecs.CodecInfo object
    The getregentry() API must return a CodecInfo object with encoder, decoder,  incrementalencoder, incrementaldecoder, streamwriter and streamreader   atttributes which adhere to the Python Codec Interface Standard.

    In addition, a module may optionally also define the following APIs which are then used by the package's codec search function:

    * getaliases() -> sequence of encoding name strings to use as aliases

    Alias names returned by getaliases() must be normalized encoding names as defined by normalize_encoding().

"""标准""编码"包

标准Python编码模块存储在这个包目录中。

编解码器模块必须具有与下面normalize_encoding()函数中定义的规范化编码名称相对应的名称，例如。“utf-8”必须由模块“utf_8.py”实现。
每个编解码器模块必须导出以下接口:

* getregentry() ->编解码器。CodecInfo对象
getregentry() API必须返回一个CodecInfo对象，该对象具有符合Python编解码接口标准的编码器、解码器、增量编码器、增量解码器、streamwriter和streamreader atttributes。

此外，模块还可以选择定义以下api，然后由包的编解码器搜索功能使用:

* getaliases() -编码名称字符串作为别名的>序列

getaliases()返回的别名必须是normalize_encoding()定义的规范化编码名。
