【问题描述】：
1。总结
我没找到，Sublime Text 插件开发者如何使用 Sublime Text 查找全局 Python 包，而不是 Sublime Text 目录的 Python 包。
Sublime Text 使用自己的 Python 环境，而不是机器的 Python 环境。 Developers needs sys.path 用于设置未内置的 Sublime Text Python 包。
是否有任何方法在 Sublime Text 插件中使用全局安装的 Python 包？例如，如果有人告诉我如何更改我的插件，那就太好了——请参阅此问题的 3.2 项。
2。使用 Sublime Text 3 环境的缺点
- Sublime Text 3 Build 3126 使用 Python 3.3，但在撰写此问题时发布 Python 3.6 稳定版。 Python 3.6 具有更多功能。
- 开发人员需要添加和更新第三方 Python 包，即使它们是为用户安装的。它花费了开发人员的时间。
- 对于开发者来说，包的依赖可能会出现问题，请参阅本问题的 6.2 项。
3。示例
1。 Python代码
例如，我编写了 Python 代码 — 将 Поиск Кристиниты 替换为 [**Поиск Кристиниты**](https://github.com/Kristinita/Kristinita.github.io)，其中 https://github.com/Kristinita/Kristinita.github.io — DuckDuckGo 查询的第一个链接 Поиск Кристиниты。
# -*- coding: utf-8 -*-
import re
import urllib
from bs4 import BeautifulSoup
from w3lib.url import safe_url_string
# ASCII link for solved encoding problems —
# https://stackoverflow.com/a/40654295/5951529
ascii_link = safe_url_string(
u'http://duckduckgo.com/html/?q=' + 'Поиск Кристиниты',
encoding="UTF-8")
print(ascii_link)
# SERP DuckDuckGo
serp = urllib.request.urlopen(ascii_link)
# Reading SERP
read_serp = serp.read()
# BeautifulSoup — https://stackoverflow.com/a/11923803/5951529
parsed = BeautifulSoup(read_serp, "lxml")
# Parsed first link
first_link = parsed.findAll(
'div', {'class': re.compile('links_main*')})[0].a['href']
# Remove DuckDuckGo specific characters —
# https://stackoverflow.com/a/3942100/5951529
remove_duckduckgo_symbols = first_link.replace("/l/?kh=-1&uddg=", "")
# https://stackoverflow.com/a/32451970/5951529
final_link = (urllib.parse.unquote(remove_duckduckgo_symbols))
# Markdown link
markdown_link = '[' + 'Поиск Кристиниты' + ']' + \
'(' + final_link + ')'
print(markdown_link)
如果我在终端或 SublimeREPL 中运行这个文件，我会得到输出：
[**Поиск Кристиниты**](https://github.com/Kristinita/Kristinita.github.io/)
2。 Sublime Text 插件
现在，基于此代码，我编写了 Sublime Text 插件，用于将 example text 替换为 [**example text**](http://<first link for DuckDuckGo query “example link”>)：
import re
import urllib
from bs4 import BeautifulSoup
from w3lib.url import safe_url_string
import sublime_plugin
class KristinitaLuckyLinkCommand(sublime_plugin.TextCommand):
def run(self, edit):
# Get selection text
print('KristinitaLuckyLink called')
select = self.view.sel()
selection_region = select[0]
selection_text = self.view.substr(selection_region)
print(selection_text)
# ASCII link for solved encoding problems —
# https://stackoverflow.com/a/40654295/5951529
ascii_link = safe_url_string(
u'http://duckduckgo.com/html/?q=' + (selection_text),
encoding="UTF-8")
print(ascii_link)
# SERP DuckDuckGo
serp = urllib.request.urlopen(ascii_link)
# Reading SERP
read_serp = serp.read()
# BeautifulSoup — https://stackoverflow.com/a/11923803/5951529
parsed = BeautifulSoup(read_serp, "lxml")
# Parsed first link
first_link = parsed.findAll(
'div', {'class': re.compile('links_main*')})[0].a['href']
# Remove DuckDuckGo specific characters —
# https://stackoverflow.com/a/3942100/5951529
remove_duckduckgo_symbols = first_link.replace("/l/?kh=-1&uddg=", "")
# Final link — https://stackoverflow.com/a/32451970/5951529
final_link = (urllib.parse.unquote(remove_duckduckgo_symbols))
markdown_link = '[' + selection_text + ']' + \
'(' + final_link + ')'
print(markdown_link)
# Replace selected text to Markdown link
self.view.replace(
edit, selection_region, markdown_link)
4。预期行为
如果用户已安装 Python 并安装包
pip install beautifulsoup4pip install lxmlpip install w3lib
我希望我的 2.2 项中的插件成功地为用户工作。
5。实际行为
如果我保存我的插件，我会得到堆栈跟踪：
Traceback (most recent call last):
File "D:\Sublime Text Build 3126 x64 For Debug\sublime_plugin.py", line 109, in reload_plugin
m = importlib.import_module(modulename)
File "./python3.3/importlib/__init__.py", line 90, in import_module
File "<frozen importlib._bootstrap>", line 1584, in _gcd_import
File "<frozen importlib._bootstrap>", line 1565, in _find_and_load

File "D:\Sublime Text Build 3126 x64 For Debug\Data\Packages\Grace Splitter\kristi.py", line 4, in <module>
from bs4 import BeautifulSoup
ImportError: No module named 'bs4'
6。没有帮助
1。使用计算机的全局 Python 环境
我不知道，我该怎么做。我可以找到的问题示例：
- How to include third party Python packages in Sublime Text 2 plugins,
- Using paramiko library in ST2 plugins,
- Best practices for plugin-deployment and packaging,
- How to import a package and call its global functions / to get their global variable values?
2。使用 Sublime Text 环境
我安装
我将我的w3lib 目录从C:\Python36\Lib\site-packages 复制到Sublime Text 的Data\Packages 目录。
我在 Sublime Text 3 控制台中运行：
>>> window.run_command("kristinita_lucky_link")
我得到堆栈跟踪：
Traceback (most recent call last):
File "D:\Sublime Text 3 x64\sublime_plugin.py", line 818, in run_
return self.run(edit)
File "D:\Sublime Text 3 x64\Data\Packages\KristinitaLuckyLink\KristinitaLuckyLink.py", line 32, in run
parsed = BeautifulSoup(read_serp, "lxml")
File "D:\Sublime Text 3 x64\Data\Packages\bs4\__init__.py", line 165, in __init__
% ",".join(features))
bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: lxml. Do you need to install a parser library?
没找到，怎么设置lxml。
3。在 2 个文件中使用变量
例如我在同一目录中有KristinitaLuckyLink.py 和KrisDuckDuckGo.py 文件。
我的KristinitaLuckyLink.py 文件：
import re
import requests
import sublime_plugin
import subprocess
import sys
sys.path.append(
'D:\Sublime Text 3 x64\Data\Packages\KristinitaLuckyLink\KrisDuckDuckGo.py')
from KrisDuckDuckGo import final_link
from bs4 import BeautifulSoup
class KristinitaLuckyLinkCommand(sublime_plugin.TextCommand):
def run(self, edit):
# Get selection text
print('KristinitaLuckyLink called')
select = self.view.sel()
selection_region = select[0]
selection_text = self.view.substr(selection_region)
print(selection_text)
# Get terminal output — https://stackoverflow.com/a/4760517/5951529
# Paths is correct
result = subprocess.run(["C:\Python36\python.exe", "D:\Sublime Text 3 x64\Data\Packages\KristinitaLuckyLink\krisduckduckgo.py"],
stdout=subprocess.PIPE)
final_link = result.stdout.decode('utf-8')
print(final_link)
# Markdown link
markdown_link = '[' + selection_text + ']' + \
'(' + final_link + ')'
print(markdown_link)
# Replace selected text to Markdown link
self.view.replace(
edit, selection_region, markdown_link)
我的KrisDuckDuckGo.py 文件：
import urllib
import sys
sys.path.append(
'D:\Sublime Text 3 x64\Data\Packages\KristinitaLuckyLink\KristinitaLuckyLink.py')
from w3lib.url import safe_url_string
from KristinitaLuckyLink import selection_text
from bs4 import BeautifulSoup
# ASCII link for solved encoding problems —
# https://stackoverflow.com/a/40654295/5951529
ascii_link = safe_url_string(
u'http://duckduckgo.com/html/?q=' + (selection_text),
encoding="UTF-8")
print(ascii_link)
# SERP DuckDuckGo
serp = urllib.request.urlopen(ascii_link)
# Reading SERP
read_serp = serp.read()
# BeautifulSoup — https://stackoverflow.com/a/11923803/5951529
parsed = BeautifulSoup(read_serp, "lxml")
# Parsed first link
first_link = parsed.findAll(
'div', {'class': re.compile('links_main*')})[0].a['href']
# Remove DuckDuckGo specific characters —
# https://stackoverflow.com/a/3942100/5951529
remove_duckduckgo_symbols = first_link.replace("/l/?kh=-1&uddg=", "")
# Final link — https://stackoverflow.com/a/32451970/5951529
final_link = (urllib.parse.unquote(remove_duckduckgo_symbols))
print(final_link)
我选择任何文本 → 我在 Sublime Text 控制台中打印：
window.run_command("kristinita_lucky_link")
我在 Sublime Text 控制台中没有得到输出。
