python-3.x - Conda:UnicodeEncodeError: 'charmap' 编解码器无法对位置 644 中的字符 '\u2580' 进行编码:字符映射到

Question

问题:
当我尝试在 conda 中切换环境时出现错误，无法激活环境。奇怪的是，在 anaconda 导航器中，我可以激活另一个环境。如果可能的话，我宁愿不安装 conda new。

我试过了:
conda 更新 conda
畅达 anaconda-navigator --reset

错误:

Traceback (most recent call last):
      File "D:\Programme\Anaconda3\lib\site-packages\conda\cli\main.py", line 138, in main
        return activator_main()
      File "D:\Programme\Anaconda3\lib\site-packages\conda\activate.py", line 1093, in main
        print(activator.execute(), end='')

Answer 1

对我来说，解决方案是设置 PYTHONIOENCODING=utf8。无需为我手动触摸解码表。

例子:

PYTHONIOENCODING=utf8 conda activate myenv
