FSL安装失败消息

Question

如https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FslInstallation/MacOsX所述 我已经按照步骤使用安装脚本安装了FSL。我是新手，不知道自己哪里出了问题，也不知道该怎么办。我也下载了最新的python。 我尝试了以下命令

cd ~/Downloads
python fslinstaller.py

及

/usr/bin/python fslinstaller.py

我也试过sudo，但是 我一直得到以下输出

--- FSL Installer - Version 3.1.0 ---
[Warning] Some operations of the installer require administative rights,
    for example installing into the default folder of /usr/local.
    If your account is an 'Administrator' (you have 'sudo' rights)
    then you will be prompted for your administrator password
    when necessary.
When asked a question, the default answer is given in square brackets.

[FAILED] [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590)

任何建议都是非常宝贵的
