1.使用python fabric进行Linux基础配置使用python,可以让任何事情高效起来,包括运维工作,fabric正式这样一套基于python2的类库,它执行本地或远程shell命令提供了操作的基本套件...用Python3开发的部署工具叫fabric3:fabric3,和fabric一样最大特点是不用登录远程服务器,在本地运行远程命令,几行Python脚本就可以轻松部...
在Linux系统中,Python解释器通常位于/usr/bin/python或/usr/bin/env python。我们可以使用which python命令来查找Python解释器的实际路径。 $whichpython /usr/bin/python 1. 2. 如果输出结果不是/usr/bin/python,而是其他路径,那么说明指定的解释器路径不正确。我们需要更新脚本的shebang行,将其指向正确的解释器路径。
现在,你应该能够成功执行脚本而不再出现“-bash: ./run.py: /usr/bin/python: bad interpreter: No such file or directory”错误。 总结 通过按照上述步骤检查Python的安装路径、确认解释器路径、检查脚本中的shebang、修改脚本的执行权限并执行脚本,你应该能够解决“-bash: ./run.py: /usr/bin/python: bad ...
