当我做source activate my_env时，会出现此错误：

λ source activate py36

你们能帮帮我吗？我只希望能够从Git Bash激活conda环境。

此外，activate my_env仅在使用常规命令提示符时有效，因此Git Bash和conda似乎存在问题。

如果需要，这是我的conda信息：

编辑：：似乎conda激活脚本通过我的bash提示进行扫描，并停留在lambda“λ”上，因为它无法识别此字符。 如果您阅读错误消息，我认为此特定部分非常突出：UnicodeEncodeError: 'charmap' codec can't encode character '\u03bb' \u03bb是lambda字符的unicode编码，但是激活脚本无法识别它。有什么方法可以更改编码，以便conda激活脚本可以识别此字符吗？

2 个答案:

答案 0 :(得分：2)

您似乎处在Cmder session中，这意味着issue 7445可能适用：

  

请注意，cmder在每个命令前都有一个lambda字符（λ）。

     

我认为是lambda charater (i.e. '\u03bb')在\lib\encodings\cp1252.py中找到的编码器/解码器类中未正确处理。

解决方法：

  

在第36行的cmder\vendor\git-for-windows\etc\profile.d\git-prompt.sh中删除lambda字符。

PS1="$PS1"''                 # prompt: always "λ "

答案 1 :(得分：0)

试试看。将lambda符号替换为“ >>”。您将需要在“ YOURPATHTOCMDER \ cmder \ vendor \ clink.lua”中找到文件，并更改函数 function set_prompt_filter（），如下所示：

function set_prompt_filter()
-- orig: $E[1;32;40m$P$S{git}{hg}$S$_$E[1;30;40m{lamb}$S$E[0m
-- color codes: "\x1b[1;37;40m"
cwd = clink.get_cwd()
prompt = "\x1b[1;32;40m{cwd} {git}{hg} \n\x1b[1;30;40m{lamb} \x1b[0m"
new_value = string.gsub(prompt, "{cwd}", cwd)
clink.prompt.value = string.gsub(new_value, "{lamb}", ">>")

结束
