UnicodeDecodeError:"charmap"编解码器无法解码位置X的字节0x9d:字符映射为< undefined> [英] UnicodeDecodeError: 'charmap' codec can't decode byte 0x9d in position X: character maps to <undefined>

问题描述

当我尝试通过pip安装 StringGenerator 时，系统提示我出现此错误:

When I'm trying to install StringGenerator with pip, I am prompted with this error:

C:\Users\Administrator> pip install StringGenerator

Collecting StringGenerator

推荐答案

问题是在安装过程中读取README.txt时引起的.在Windows中，默认编码为cp1252，但是该自述文件很可能使用UTF8编码.

The problem is caused during the setup process when reading README.txt. In Windows, the default encoding is cp1252, but that readme file is most likely encoded in UTF8.

该错误消息告诉您cp1252编解码器无法解码字节0x9D的字符.浏览自述文件​​时，发现以下字符:(也称为"RIGHT DOUBLE QUOTATION MARK")，其字节为0xE2 0x80 0x9D ，其中包括有问题的字节.

The error message tells you that cp1252 codec is unable to decode the character with the byte 0x9D. When I browsed through the readme file, I found this character: " (also known as: "RIGHT DOUBLE QUOTATION MARK"), which has the bytes 0xE2 0x80 0x9D, which includes the problematic byte.

您可以做的是:

1. 在此处
下载软件包
2. 解压缩程序包
3. 打开setup.py
4. 更改以下内容:

1. Download the package here
2. Decompress the package
3. Open setup.py
4. Change the following:

发件人:

with open('README.txt') as file:
    long_description = file.read()

更改为:

with open('README.txt', encoding="utf8") as file:
    long_description = file.read()

这将使用正确的编码打开文件.

This will open the file with the proper encoding.

或者您可以完全删除这两行，也可以在setup()内部的第18行删除long_description=long_description,.

Or you can remove these two line altogether and also remove long_description=long_description, at line 18 inside setup().

1. 在控制台中，运行python setup.py install
2. 您完成了！

---

由于setup.py脚本中没有实际的设置，因此您可以直接从 GitHub ，该软件包仍应正常运行.

---

Since there's no actual setup in the setup.py script, you can just directly clone the source folder from GitHub, the package should still work properly.
