Fatal Python error: Py_Initialize: unable to load the file system codec
Traceback (most recent call last):
File "f:\program files\python\python36\lib\encodings\__init__.py", line 31, in <module>
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。

解决方法
1、第一次尝试—在系统环境变量内添加路径
PYTHONPATH
F:/Program Files/Python/Python36/Lib
