如何修复virtualenv中“太多级别的符号链接”错误？

Question

我在Django Web应用程序框架中设置虚拟环境时遇到错误（符号链接级别太多）。

我试着在堆栈溢出上查看以下问题和答案：

mkvirtualenv: Too many levels of symbolic links

virtualenv: Too many levels of symbolic links

-bash: /Users/kuldeep/Dev/trydjango/bin/pip: /Users/kuldeep/Dev/trydjango/bin/python3: bad interpreter: Too many levels of symbolic links

ls -l对bin文件夹说：
