bash: python: 找不到命令

Question

我最近在 Ubuntu 上安装了 Sublime text。当我尝试运行某些 python 代码时，弹出以下错误：

bash: python: command not found
[Finished in 0.0s with exit code 127]
[shell_cmd: python -u "/home/user/Desktop/Python Project/test.py"]
[dir: /home/user/Desktop/Python Project]
[path: /home/user/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin]

当我运行 python 在命令行上，我得到：


  command 'python3' from deb python3
  command 'python' from deb python-is-python3

当我运行 python3 在命令行上，我得到：

Python 3.8.2 (default, Apr 27 2020, 15:53:34) 
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

Answer 1

Sublime Text 正在配置 python 而不是 python3。您只需要向 Sublime Text 添加一个新的构建系统。为此，Select Tools > Build System > New Build System... 现在，将打开一个新文件。将以下代码添加到此文件中：

{
    "cmd": ["/usr/bin/python3", "-u", "$file"],
    "file_regex": "^[ ]File \"(...?)\", line ([0-9]*)",
    "selector": "source.python"
}

现在，将文件另存为 Python3.sublime-build。现在，将您的 Build System 更改为 Python3 并尝试运行您再次编码。现在，它应该运行成功。
