当我启动 Ubuntu 18.04 或切换用户时，弹出一条错误消息：
" Error found when loading /etc/profile:
/usr/share/modules/init/sh: line 36: /usr/bin/tclsh: No such file or directory
/usr/share/modules/int/sh: line 61: export: module: not a function
As a result the session will not be configured correctly, you should fix the problemas soon as feasable."
如果有人能建议如何解决这个问题，那就太好了！
