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 <未定义>

Question

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

\n\n

我尝试过：
\nconda update conda
\nconda anaconda-navigator --reset

\n\n

错误：

\n\n

Traceback (most recent call last):\n      File "D:\\Programme\\Anaconda3\\lib\\site-packages\\conda\\cli\\main.py", line 138, in main\n        return activator_main()\n      File "D:\\Programme\\Anaconda3\\lib\\site-packages\\conda\\activate.py", line 1093, in main\n        print(activator.execute(), end=\'\')\n      File "D:\\Programme\\Anaconda3\\lib\\encodings\\cp1252.py", line 19, in encode\n        return codecs.charmap_encode(input,self.errors,encoding_table)[0]\n    UnicodeEncodeError: \'charmap\' codec can\'t encode character \'\\u2580\' in position 644: character maps to <undefined>\n

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
