如何使python3.7預設
我已經安裝了 python3.7 但是我不知道如何使它成為預設的 python。
見下文:
~/Documents/robosuite$ python3.7 Python 3.7.1 (default, Oct 22 2018, 11:21:55) [GCC 8.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> KeyboardInterrupt >>> ~/Documents/robosuite$ python3 Python 3.6.7 (default, Oct 22 2018, 11:32:17) [GCC 8.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>>
我希望在使用命令時顯示 python3.7
python3
簡單的解決方案是編輯
.bashrc
並放入這一行:alias python3=python3.7
每當您編寫
python3
它時,它都會將其替換為python3.7
.或者您可以使用
update-alternatives
首選的命令,即:sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 1 sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.7 2
所以這裡
python3.7
會有更高的優先級python3.6
。然後使用:sudo update-alternatives --config python3
滿意按輸入鍵
