我正在为主要以 utf-8 编码的 Python 项目创建自己的cookiecutter 模板。但它包含以 iso-8859-1 (latin1) 编码的文件.ini。.php此资源必须以 latin1 编码，因为它是遗留代码的一部分。

当我运行时：

cookiecutter cookiecutter-mytemplate  # <- directory of my project

在代码生成过程中出现以下错误：

Traceback (most recent call last):
  ...
  File ".../lib/python2.7/site-packages/cookiecutter/cli.py", line 123, in main
    default_config=default_config,

    source, filename, uptodate = self.get_source(environment, name)

    contents = f.read().decode(self.encoding)
  File ".../lib/python2.7/encodings/utf_8.py", line 16, in decode
    return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xe9 in position 308: invalid continuation byte

当然，结果是部分生成的，在解析iso-8859-1文件时被中断（里面有一个“é”）。

我可以在生成模板之前使用 pre-/post- hook 将我的资源转换为 utf-8，然后再将它们转换回 iso-8859-1？如何？

有没有办法处理非 utf-8 文件？

最后，我将所有我的.ini和.php文件存储在 utf-8 中，并使用钩子在后生成中转换 iso-8859-1 中的文件。

这是代码hooks/post_gen_project.py：

# coding: utf-8
from __future__ import print_function, unicode_literals

import io
import os


def convert_resources(src_dir):
    if "src" in os.listdir(src_dir):
        src_dir = os.path.join(src_dir, "src")
    print("src_dir: " + src_dir)

    for root_dir, dirnames, filenames in os.walk(src_dir):
        for filename in filenames:
            ext = os.path.splitext(filename)[1]
            if ext in ('.ini', '.php'):
                src_path = os.path.join(root_dir, filename)
                print("  Converting '{relpath}'...".format(relpath=os.path.relpath(src_path, src_dir)))
                with io.open(src_path, mode="r", encoding="utf-8") as fd:
                    content = fd.read()
                with io.open(src_path, mode="w", encoding="iso-8859-1") as fd:
                    fd.write(content)


if __name__ == '__main__':
    convert_resources(os.getcwd())
