尝试在终端中运行Python解释器时的ModuleNotFoundError

Question

当我尝试在终端中运行Python时，我收到以下错误：

Failed to import the site module
Traceback (most recent call last):
  File "/Users/joshlee/anaconda3/lib/python3.6/site.py", line 541, in <module> 
    main()
  File "/Users/joshlee/anaconda3/lib/python3.6/site.py", line 522, in main
    known_paths = addusersitepackages(known_paths)
  File "/Users/joshlee/anaconda3/lib/python3.6/site.py", line 282, in addusersitepackages
    user_site = getusersitepackages()
  File "/Users/joshlee/anaconda3/lib/python3.6/site.py", line 258, in getusersitepackages
    user_base = getuserbase() # this will also set USER_BASE
  File "/Users/joshlee/anaconda3/lib/python3.6/site.py", line 248, in getuserbase 
    USER_BASE = get_config_var('userbase')
  File "/Users/joshlee/anaconda3/lib/python3.6/sysconfig.py", line 601, in get_config_var 
    return get_config_vars().get(name)
  File "/Users/joshlee/anaconda3/lib/python3.6/sysconfig.py", line 550, in get_config_vars 
    _init_posix(_CONFIG_VARS)
  File "/Users/joshlee/anaconda3/lib/python3.6/sysconfig.py", line 421, in _init_posix 
    _temp = __import__(name, globals(), locals(), ['build_time_vars'], 0)
ModuleNotFoundError: No module named '_sysconfigdata_m_darwin_darwin'

我有一段时间没有碰过Python，现在我收到了这个错误。这是怎么回事？
