OSError：[Errno 17]激活环境时存在FIle

Question

我正在安装Conda，我按照步骤创建了一个环境，但这里总是有错误。

shiyu@epsilon-27:~/Downloads$ source activate my_environment
Traceback (most recent call last):
File "/usr/local/bin/conda", line 5, in <module>
sys.exit(main())
File "/usr/local/lib/python2.7/dist-packages/conda/cli/main.py", line 67, in main
activate.main()
File "/usr/local/lib/python2.7/dist-packages/conda/cli/activate.py", line 99, in main
conda.install.symlink_conda(join(binpath, '..'), conda.config.root_dir)
File "/usr/local/lib/python2.7/dist-packages/conda/install.py", line 371, in symlink_conda
os.symlink(root_conda, prefix_conda)
OSError: [Errno 17] File exists`

有人能帮助我吗？谢谢！
