在Python 3中,有时可能会遇到“No module named ‘encodings’”的错误。这个问题通常是由于Python环境配置不当或缺少必要的模块引起的。下面我们将探讨这个问题的可能原因和解决方案。问题原因: Python环境配置问题:可能是由于Python环境变量未正确配置,导致Python无法找到encodings模块。 缺少必要的模块:encodings模块是Pyth...
1. cd /usr/local/python-3.6 1. ./configure 1. make && make install 1. python3 -V 1. 二:安装并创建虚拟环境 建议使用这个命令安装virtualenv --python=/usr/bin/python3 vnev(虚拟环境名称) 以前用的pip3 install virtualenv命令安装 会出现这个错误ImportError: No module named ‘encodings’ 创建一...

Multi-byte encodings, where each character is represented by a variable number of bytes. Examples: Big5 (Chinese), SHIFT_JIS (Japanese), EUC-KR (Korean), and UTF-8 without a BOM. Single-byte encodings, where each character is represented by one byte. Examples: KOI8-R (Russian), windows...
If I recall, the reason for passing around byte/unicode strings equivalently was to try to handle invalid filename encodings. At least in Python 2, I recall that if filenames didn't decode properly with the current locale, they would be returned as a byte string instead of a unicode ...
