在 Linux 配置 Python3 的环境
司徒池暝
1. 安装 sublime
直接参考官网用命令安装 https://www.sublimetext.com/
2. 安装 Python 和 pip
2.1 安装 Python
进入到当前用户的 Downloads 目录：
su yin # 切换用户
cd
cd Downloads
下载一个版本的源文件，注意根据需求修改版本号：
wget https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz
解压并移动到 /usr/local 目录下，命名为 python3，可能需要权限，加上 sudo 前缀即可
cd Downloads/
tar -zxvf Python-3.7.5.tgz
mv Python-3.7.5 /usr/local #目录可以自己选择
cd /usr/local/
mv Python-3.7.5 python3
进入 python3 目录，编译
cd python3
./configure --prefix=/usr/local/python3 #python3的所在目录绝对路径
make
make install
安装成功，创建软链接，方便使用：
ln -s /usr/local/python3/bin/python3.5 /usr/bin/python3
python3
出现下面的结果即安装成功：
Python 3.7.5 (default, Dec 4 2021, 10:35:11)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> print(123)
123
注意：此时系统有两个 Python 版本，一个是自带的 Python2.7.x，另一个是新的，在终端输入 python 会运行 Python 2.7.x，输入 python3 才会运行新安装的 Python !
接着安装 pip（参考博客 https://blog.csdn.net/A156348933/article/details/85321935）
3. 配置 Sublime
3.1 Package Control
好像 package control 是自带的，如果没有可以试试在console 运行下面的代码，或者用其他办法
import urllib.request,os,hashlib; h = '6f4c264a24d933ce70df5dedcf1dcaee' + 'ebe013ee18cced0ef93d5f746d80ef60'; pf = 'Package Control.sublime-package'; ipp = sublime.installed_packages_path(); urllib.request.install_opener( urllib.request.build_opener( urllib.request.ProxyHandler()) ); by = urllib.request.urlopen( 'http://packagecontrol.io/' + pf.replace(' ', '%20')).read(); dh = hashlib.sha256(by).hexdigest(); print('Error validating download (got %s instead of %s), please try manual install' % (dh, h)) if dh != h else open(os.path.join( ipp, pf), 'wb' ).write(by)
3.2 build system
点击 tools-build system-new build system，创建新的 build-system，输入下面的代码：
{
"cmd": ["/usr/bin/python3", "-u", "$file"],
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
"selector": "source.python"
}
文件另存为 python3.sublime-build，接着在 tools - build system 中选择 python3
此时，可以通过 tools - build 运行代码
3.2 Sublime REPL
step1：按快捷键 Ctrl+shidt+P 打开 package control，输入 install，安装 sublime repl
step2：打开 preferences-key Bindings，下面的代码粘贴进去
[
{
"keys":["ctrl+b"],
"caption": "SublimeREPL: Python - RUN current file",
"command": "run_existing_window_command",
"args": {
"id": "repl_python_run",
"file": "config/Python/Main.sublime-menu"}
} ,
{
"keys": ["f8"],
"caption": "SublimeREPL: Python - PDB current file",
"command": "run_existing_window_command",
"args": {
"id": "repl_python_pdb",
"file": "config/Python/Main.sublime-menu"}
}
]
此时，使用 ctrl+b 就可以运行交互式地 python 了
step3：设置 REPL 使用 python 3
运行下面的代码：
import os
print(os.sys.version)
点击 tools - build 会得到 3.7.5
而通过ctrl + b 得到的结果确是 2.7.x，而且无法导入 pip 安装的库
分析：REPL 要设置使用 Python3！
首先，点击 Preferences - Browser Packages 打开目录，进入 Sublime REPL - config，可以看到里面有 Python 文件夹，这是默认的 Python2.7.x，复制这个 Python 文件夹，副本重命名为 Python3
进入Python3，修改文件 Default-sublime-commands：
[
{
"caption": "SublimeREPL: Python3",
"command": "run_existing_window_command", "args":
{
"id": "repl_python3",
"file": "config/Python3/Main.sublime-menu"
}
},
{
"caption": "SublimeREPL: Python - PDB current file",
"command": "run_existing_window_command", "args":
{
"id": "repl_python_pdb",
"file": "config/Python3/Main.sublime-menu"
}
},
{
"caption": "SublimeREPL: Python3 - RUN current file",
"command": "run_existing_window_command", "args":
{
"id": "repl_python3_run",
"file": "config/Python3/Main.sublime-menu"
}
},
{
"command": "python_virtualenv_repl",
"caption": "SublimeREPL: Python - virtualenv"
},
{
"caption": "SublimeREPL: Python - IPython",
"command": "run_existing_window_command", "args":
{
"id": "repl_python_ipython",
"file": "config/Python3/Main.sublime-menu"
}
}
]
接着修改 Main.sublime-menu:
[
{
"id": "tools",
"children":
[{
"caption": "SublimeREPL",
"mnemonic": "R",
"id": "SublimeREPL",
"children":
[
{"caption": "Python3",
"id": "Python3",
"children":[
{"command": "repl_open",
"caption": "Python3",
"id": "repl_python3",
"mnemonic": "P",
"args": {
"type": "subprocess",
"encoding": "utf8",
"cmd": ["python3", "-i", "-u"],
"cwd": "$file_path",
"syntax": "Packages/Python/Python.tmLanguage",
"external_id": "python3",
"extend_env": {"PYTHONIOENCODING": "utf-8"}
}
},
{"command": "python_virtualenv_repl",
"id": "python_virtualenv_repl",
"caption": "Python - virtualenv"},
{"command": "repl_open",
"caption": "Python - PDB current file",
"id": "repl_python_pdb",
"mnemonic": "D",
"args": {
"type": "subprocess",
"encoding": "utf8",
"cmd": ["python3", "-i", "-u", "-m", "pdb", "$file_basename"],
"cwd": "$file_path",
"syntax": "Packages/Python/Python.tmLanguage",
"external_id": "python3",
"extend_env": {"PYTHONIOENCODING": "utf-8"}
}
},
{"command": "repl_open",
"caption": "Python - RUN current file",
"id": "repl_python_run",
"mnemonic": "R",
"args": {
"type": "subprocess",
"encoding": "utf8",
"cmd": ["python3", "-u", "$file_basename"],
"cwd": "$file_path",
"syntax": "Packages/Python/Python.tmLanguage",
"external_id": "python3",
"extend_env": {"PYTHONIOENCODING": "utf-8"}
}
},
{"command": "repl_open",
"caption": "Python - IPython",
"id": "repl_python_ipython",
"mnemonic": "I",
"args": {
"type": "subprocess",
"encoding": "utf8",
"autocomplete_server": true,
"cmd": {
"osx": ["python3", "-u", "${packages}/SublimeREPL/config/Python/ipy_repl.py"],
"linux": ["python3", "-u", "${packages}/SublimeREPL/config/Python/ipy_repl.py"],
"windows": ["python3", "-u", "${packages}/SublimeREPL/config/Python/ipy_repl.py"]
},
"cwd": "$file_path",
"syntax": "Packages/Python/Python.tmLanguage",
"external_id": "python3",
"extend_env": {
"PYTHONIOENCODING": "utf-8",
"SUBLIMEREPL_EDITOR": "$editor"
}
}
}
]}
]
}]
}
]
最后，不要忘了修改 key Bindings中快捷键的设置，把原来调用 Python 改为 Python3：
"file": "config/Python3/Main.sublime-menu"}
重启 sublime，使用 ctrl + B 就可以运行 Python3 啦！
