Python 腳本在 Sublime Text 中運行時不起作用，但在命令行中運行

Question

我有一個非常簡單的腳本，它只讀入一個文件，當我從 Sublime Text 中運行它時，它現在以某種方式工作，但當我從命令行調用 Python 時工作正常。 我想知道為什么？

似乎在 open() 中，在一種情況下默認編碼是 utf-8，但在另一種情況下不是。 為什么會這樣？ Python 可執行文件對於兩者都是相同的，並且兩者似乎在路徑中具有相同的核心 Python 庫。

腳本：

import sys
print(sys.executable)
print(sys.path)
open('foo.txt').read()
print('Life is wonderful.')

激活 virtualenv 后從命令行運行時為 Output：

/Users/bemmu/Dropbox/b2/babynames/env/bin/python3
['/Users/bemmu/Dropbox/b2/babynames', '/Users/bemmu/Dropbox/b2/babynames', '/Users/bemmu/b2/python_include_dir', '/Library/Python/2.5/site-packages/elementtree-1.2.7_20070827_preview-py2.5.egg', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python36.zip', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/lib-dynload', '/Users/bemmu/Dropbox/b2/babynames/env/lib/python3.6/site-packages', '/Users/bemmu/Dropbox/b2/babynames/env/lib/python3.6/site-packages/fasttext-0.9.2-py3.6-macosx-10.6-intel.egg']
Life is wonderful.

從 Sublime Text 3 運行時為 Output：

/Users/bemmu/Dropbox/b2/babynames/env/bin/python3

構建系統：

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

您需要在構建系統中設置 LANG 環境變量。

例如：

{
    "env": {"LANG":"en_US.UTF-8"},
    "cmd": ["env/bin/python3", "$file"],
    "selector": "source.python",
    "file_regex": "^\\s*File \"(...*?)\", line ([0-9]*)"
}
