[Ifeffit] Larch single-file installers problem on Mac

[朱宥銓]

Hi everyone,
I had a problem when I tried to launch XAS software “Larch” on Mac through single-file installers. After I followed the tutorial and  installed it (double click the dmg file), when I typed the command “larch”, the terminal showed the followings:

could not read history from /Users/willie/.larch/history.lar
[Errno 13] Permission denied: '/Users/willie/.larch/init.lar'
[Errno 13] Permission denied: '/Users/willie/.larch/history.lar'

[Errno 2] No such file or directory: '/Users/willie/.larch/plugins/README'
Traceback (most recent call last):

    for pname in sorted(os.listdir(plugins_dir)):
FileNotFoundError: [Errno 2] No such file or directory: '/Users/willie/.larch/plugins’

Does anyone face this problem as well? How can I fix this problem?

Thank you,

Youchiuan
