问题描述

VSCode 在安装 Python 插件的情况下自动提示配置 Conda 环境，但是在自动配置完成后启动 powershell 会报错 UnicodeEncodeError: ‘gbk’ codec can’t encode character ‘\ue1bb’ in position 491: illegal multibyte sequence，然而在外部中断中却不会出现，猜测是由于 Python 插件解析错误

An unexpected error has occurred. Conda has prepared the above report.
If you suspect this error is being caused by a malfunctioning plugin,
consider using the --no-plugins option to turn off plugins.

Example: conda --no-plugins install <package>

Alternatively, you can set the CONDA_NO_PLUGINS environment variable on
the command line to run the command without plugins enabled.

Example: CONDA_NO_PLUGINS=true conda install <package>

问题定位

ctrl + click 跳转到对应文件，可以看到这样一个函数

def main_sourced(shell, *args, **kwargs):
    """Entrypoint for the "sourced" invocation of CLI interface. E.g. `conda activate`."""
    shell = shell.replace("shell.", "", 1)

    # This is called any way later in conda.activate, so no point in removing it
    from ..base.context import context

    context.__init__()
    init_loggers()

    from ..activate import _build_activator_cls

    try:
        activator_cls = _build_activator_cls(shell)
    except KeyError:
        from ..exceptions import CondaError

        raise CondaError("%s is not a supported shell." % shell)

    activator = activator_cls(args)
    print(activator.execute(), end="")
    return 0

查阅资料可知，python 的 print 函数存在限制，不能打印全部的 unicode 字符

解决方案

1. 文件顶部引入 io

import io
1

2. 函数中设置编码格式为 gb18030

def main_sourced(shell, *args, **kwargs):
    """Entrypoint for the "sourced" invocation of CLI interface. E.g. `conda activate`."""
    shell = shell.replace("shell.", "", 1)

    # This is called any way later in conda.activate, so no point in removing it
    from ..base.context import context

    context.__init__()
    init_loggers()

    from ..activate import _build_activator_cls

    try:
        activator_cls = _build_activator_cls(shell)
    except KeyError:
        from ..exceptions import CondaError

        raise CondaError("%s is not a supported shell." % shell)

    activator = activator_cls(args)
    sys.stdout = io.TextIOWrapper(sys.stdout.buffer,encoding='gb18030') 
    print(activator.execute(), end="")
    return 0
