如何解决在Apache2中：在标头错误调用python脚本之前，脚本输出结束我做错了什么？
我在从apache2运行python脚本时遇到问题。 我正处在从完全用python编写的简单网络服务器运行OK三年到使用apache的早期阶段，因此python代码中的许多输入和输出似乎是错误的。 我在Armbian'Buster'上安装的新apache2服务器正确找到了这个index.html
<!DOCTYPE html>
<HTML lang="en">
<HEAD>
<meta charset="utf-8">
<TITLE> Authentication </TITLE> <br />
</HEAD>
<H3><big><big> Enter Username and Password
<BODY>
<form action=/cgi-bin/processIndex.py method="post">
<div>
<label for="user"> User Name: </label>
<input maxlength="20" size="20" type="text" id="user" name="user" value="" > <br><br
/>
<label for="pass"> Password: </label>
<input maxlength="40" size="40" type="text" id="pass" name="pass" value="" > <br />
<br />
</div> <br />
<INPUT TYPE="hidden" name="reverse" value="index.html">
<INPUT TYPE="hidden" name="retry" value="index.html">
<INPUT TYPE="hidden" name="forward" value="introduction.html">
<INPUT TYPE="submit" name="submit" value="Clear">
<INPUT TYPE="Submit" name="submit" value="Submit">
</FORM>
</BODY>
</HTML>
填写表格并单击“清除”或“提交”后，我得到 “内部服务器错误”页面以及/var/log/apache2/error.log中的此错误

在脚本路径中一直设置适当的权限
ls -al /var/www/html/cgi-bin | grep processIndex
-rwxr-xr-x 1 waterctl waterctl 2433 Nov 10 12:38 processIndex.py
在终端上调用/ usr / bin / python将启动python 3.7解释器 显然，服务器已找到脚本的正确路径。 这是脚本

我没有正确做些什么？
