Fatal Python error: Py_Initialize: unable to load the file system codec
Traceback (most recent call last):

ModuleNotFoundError: No module named 'codecs'

 

 

 

解决思路

模块未找到错误:没有命名为“codecs”的模块

""" 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。 作者Marc-Andre Lemburg ([email protected])。 (c) CNRI版权所有不保修的。
