安装turtle库时出错

Question

错误如下：

WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

Answer 1

在代码中，代码中的except旁边有一个语法错误

根据错误，您需要将第1行更改为：

except ValueError:
    #your code here

希望这有帮助
