python - AppVeyor中的UTF-8，Python 3.6

1.总结

我找不到如何在AppVeyor构建中使用非ascii符号的方法。

2.设定

我的简单 SashaAppVeyorEncoding.py 文件:

print('Саша наилучшая!')

我的简单 appveyor.yml 文件:

environment:

  matrix:

    - PYTHON: "C:\\Python36-x64"
      PYTHON_VERSION: "3.6.3"
      PYTHON_ARCH: "64"
      PIP: "C:\\Python36-x64\\Scripts\\pip"

platform: x64

build_script:

  - cmd: "%PYTHON%\\python SashaAppVeyorEncoding.py"

我用UTF-8编码保存了这两个文件。

3.预期行为

如果我在终端或解释器SublimeREPL中运行SashaAppVeyorEncoding.py文件，则会得到:

D:\SashaPythonista>python SashaAppVeyorEncoding.py
Саша наилучшая!

如果我的SashaAppVeyorEncoding.py文件不包含西里尔符号:

print('Sasha superior!')

AppVeyor构建successful passed:

Build started
git clone -q --branch=master https://github.com/Kristinita/SashaPythonista.git C:\projects\sashapythonista-7l3yk
git checkout -qf 3a0393a5b9548a5debabebfc5e28d17f3000a768
%PYTHON%\python SashaAppVeyorEncoding.py
Sasha superior!
Discovering tests...OK
Build success

4.实际行为

My AppVeyor build failed:

Build started
git clone -q --branch=master https://github.com/Kristinita/SashaPythonista.git C:\projects\sashapythonista-7l3yk
git checkout -qf 262cef287d45b1548640b9a773b680de90b7d138

    return codecs.charmap_encode(input,self.errors,encoding_table)[0]

Command exited with code 1

5.没有帮助

我在# -*- coding: utf-8 -*-文件

的顶部添加SashaAppVeyorEncoding.py

我将add chcp 65001 命令传递给appveyor.yml文件

我install win-unicode-console 到appveyor.yml文件

我更新的SashaAppVeyorEncoding.py文件:

# -*- coding: utf-8 -*-
print('Саша наилучшая!')

我更新的appveyor.yml文件:

environment:

  matrix:

    - PYTHON: "C:\\Python36-x64"
      PYTHON_VERSION: "3.6.3"
      PYTHON_ARCH: "64"
      PIP: "C:\\Python36-x64\\Scripts\\pip"

platform: x64

install:

  - cmd: "%PIP% install win-unicode-console"
  - cmd: chcp 65001

build_script:

  - cmd: "%PYTHON%\\python SashaAppVeyorEncoding.py"

我的updated AppVeyor build:

Build started
git clone -q --branch=master https://github.com/Kristinita/SashaPythonista.git C:\projects\sashapythonista-7l3yk
git checkout -qf 11df07d4c424cd8e28a1b0db0f43906aa63f42f1

6.本地环境

操作系统和版本:
Windows 10企业版LTSB 64位EN
Python:
3.6.3
chcp:
事件代码页:65001

最佳答案

看来python不会打印到AppVeyor的控制台上-输出已重定向。因此，在打印到标准输出时， locale.getpreferredencoding() 用于将Unicode文本编码为字节。 cp1252仅支持一百万个Unicode字符中的几个。要在此处更改sys.stdout.encoding，您可以 set PYTHONIOENCODING=utf-8 envvar-utf-8字符编码支持所有Unicode字符。
