python - AppVeyor 中的 UTF-8，Python 3.6

Question

1。总结

我没有找到如何将非 ascii 符号用于 AppVeyor 构建。

---

2。设置

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"

我以 UTF-8 编码保存的两个文件。

3。预期行为

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

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
%PYTHON%\python SashaAppVeyorEncoding.py

5。没有帮助

1. 我在 SashaAppVeyorEncoding.py 文件的顶部添加了 # -*- coding: utf-8 -*-，
2. 我 add chcp 65001命令到 appveyor.yml 文件，
3. 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

Answer 1

看起来 python 没有打印到 AppVeyor 上的控制台——输出被重定向了。因此locale.getpreferredencoding()用于在打印到标准输出时将 Unicode 文本编码为字节。 cp1252 仅支持百万个 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。
