蟒蛇无法安装PyICU

Question

我的系统是Windows10 x86_64，Anaconda3。

我最初的目标是安装用于本地语言处理的polyglot。Polyglot需要PyICU才能正常工作。

但是，默认安装PyICU的方式不起作用：

(C:\ProgramData\Anaconda3) C:\WINDOWS\system32>pip install pyicu
Collecting pyicu
  Using cached PyICU-1.9.7.tar.gz
Exception:
Traceback (most recent call last):
  File "C:\ProgramData\Anaconda3\lib\site-packages\pip\compat\__init__.py", line 73, in console_to_str
    return s.decode(sys.__stdout__.encoding)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcd in position 32: invalid continuation byte

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\ProgramData\Anaconda3\lib\site-packages\pip\basecommand.py", line 215, in main
    status = self.run(options, args)
  File "C:\ProgramData\Anaconda3\lib\site-packages\pip\commands\install.py", line 335, in run
    wb.build(autobuilding=True)
  File "C:\ProgramData\Anaconda3\lib\site-packages\pip\wheel.py", line 749, in build
    self.requirement_set.prepare_files(self.finder)
  File "C:\ProgramData\Anaconda3\lib\site-packages\pip\req\req_set.py", line 380, in prepare_files
    ignore_dependencies=self.ignore_dependencies))
  File "C:\ProgramData\Anaconda3\lib\site-packages\pip\req\req_set.py", line 634, in _prepare_file
    abstract_dist.prep_for_dist()
  File "C:\ProgramData\Anaconda3\lib\site-packages\pip\req\req_set.py", line 129, in prep_for_dist
    self.req_to_install.run_egg_info()
  File "C:\ProgramData\Anaconda3\lib\site-packages\pip\req\req_install.py", line 439, in run_egg_info
    command_desc='python setup.py egg_info')
  File "C:\ProgramData\Anaconda3\lib\site-packages\pip\utils\__init__.py", line 676, in call_subprocess
    line = console_to_str(proc.stdout.readline())
  File "C:\ProgramData\Anaconda3\lib\site-packages\pip\compat\__init__.py", line 75, in console_to_str
    return s.decode('utf_8')
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcd in position 32: invalid continuation byte

(C:\ProgramData\Anaconda3) C:\WINDOWS\system32>

因此，基本上，控制台编码和utf-8都不起作用。

怎么会这样?我的视窗的区域设置是ru_RU，但字符串似乎不是俄语。(尽管有可能我只是没能成功解码它。)

该怎么办呢？

(C:\ProgramData\Anaconda3) C:\WINDOWS\system32>conda install icu="57.1"
Fetching package metadata ...........
Solving package specifications: .

# All requested packages already installed.
# packages in environment at C:\ProgramData\Anaconda3:
#
icu                       57.1                     vc14_0  [vc14]

(C:\ProgramData\Anaconda3) C:\WINDOWS\system32>

Answer 1

我不是很确定你的安装有什么问题(不能重现它)，但在Windows上安装PyICU似乎是一件相当不方便的事情，因为它需要你从源代码构建软件包，这反过来又要求所有必要的构建工具，库和包含，都在适当的位置和匹配的版本。

为什么不考虑从here安装一个预构建的包呢

> pip install PyICU-1.9.7-xx-xx-win_amd64.whl

Answer 2

您应该尝试从here下载相应的whl文件

然后以管理员身份打开Anaconda提示符，并执行以下命令：

python -m pip install <Path to whl here>\PyICU‑2.3.1‑cp37‑cp37m‑win_amd64.whl
