Question

晚上好，

我目前正在参加python的入门课程，并遇到了一个我无法解决的问题。我确信在我的代码中某处出现了一个简单的错误，但我无法找到任何解决我问题的问题。

奇怪的是，从cygwin执行它时编译并运行正常......

我在通过第三方测试（我无权访问）进行验证时遇到此错误：

Python脚本，ASCII文本可执行文件，带有CRLF行终止符

这是我的代码：

    height = float(input("What is the plane's elevation in metres? \r\n"))
    height = format(height * 3.28084, '.2f')

    speed = float(input("What is the plane's speed in km/h? \r\n"))
    speed = format(speed * 0.62137, '.2f')

    temperature = float(input("Finally, what is the temperature (in celsius) outside? \r\n"))
    temperature = format(temperature * (9/5) + 32, '.2f') 

    print("""\n########### OUTPUT ###########\n\nThe elevation is {feet} above the sea level, \n
you are going {miles} miles/h, \n
finally the temperature outside is {temp} degrees fahrenheit \n
########### OUTPUT ###########""".format(feet=height, miles=speed, temp=temperature))

这是一个基于它的cgi（两者都抛出相同的错误）：

 #!/usr/bin/env python3
# -*- coding: utf-8 -*- 


# To write pagecontent to sys.stdout as bytes instead of string
import sys
import codecs


#Enable debugging of cgi-.scripts
import cgitb
cgitb.enable()


# Send the HTTP header
#print("Content-Type: text/plain;charset=utf-8")
print("Content-Type: text/html;charset=utf-8")
print("")


height = format(1100 * 3.28084, '.2f')

speed = format(1000 * 0.62137, '.2f')

temperature = format(-50 * (9/5) + 32, '.2f')


toPrint = """\n########### OUTPUT ###########\n\nThe elevation is {feet} above the sea level, \n
you are going {miles} miles/h, \n
finally the temperature outside is {temp} degrees fahrenheit \n
########### OUTPUT ###########"""

toPrint.format(feet=height, miles=speed, temp=temperature)

# Here comes the content of the webpage 
content = """<!doctype html>
<meta charset="utf-8">
<title>Min redovisnings-sida</title>
<pre>
<h1>Min Redovisnings-sida </h1>




</pre>

<body>
 {printer}
</body>

"""


# Write page content
sys.stdout = codecs.getwriter("utf-8")(sys.stdout.detach())
sys.stdout.write(content.format(printer=toPrint))

Answer 1

您需要将CRLF转换为LF，为此您可以运行此命令：

如果您需要将其应用于特定文件夹内容，请使用文件夹中的以下命令：

dos2unix your_file

您需要先安装 dos2unix 包：

find . -type f -exec dos2unix {} \;

ASCII文本可执行文件，带有CRLF行终止符
