 3. 存檔以後，執行以下列指令編譯輸出完整文件，以確保你的修改沒有 reST 的語法錯誤或警告 ::
 
-    VERSION=3.12 make all
+    make all
 
    或者只想快速檢查是否有 reST 語法錯誤 ::
 
-    VERSION=3.12 make lint
+    make lint
 
    確保輸出中沒有任何關於正在翻譯的檔案的警告訊息。
 
    在 ``make all`` 後，可以使用 ``make build`` 來只對單一 ``.po`` 檔進行編譯，可以節省較多的時間 ::
 
-    VERSION=3.12 make build glossary.po
+    make build glossary.po
 
    如果你還沒有執行 `維護、預覽`_ 的 clone CPython 的動作，此指令會自動幫你 clone CPython，\
    並且會使用 Sphinx 幫你檢查 reST 語法錯誤，我們盡量保持沒有 warning \
