Question

我在远程服务器上的apache上部署了我的Flask应用程序，但是当调用load_transcript（）函数时，我得到了一个FileNotFoundError。但是，调用download_sound_file（）函数时，我不会收到此错误。这两个功能在我的本地部署中完美运行。我在下面提供了我的目录结构。有人可以提供一些有关如何调试的建议吗？

以下是app.py中的相关代码：

def readFile(filename):
    fileSegments = []
    with open(filename, 'r') as csvfile:
        spamreader = csv.reader(csvfile, delimiter='\t', quotechar='|')
        for row in spamreader:
            outputDict = {}
            outputDict["id"] = row[0]
            outputDict["speakerID"] = row[1]
            outputDict["text"] = row[2]
            fileSegments.append(outputDict)
    return fileSegments

@app.route('/transcript/<meetingid>')
def load_transcript(meetingid):
    template_variables = {}
    template_variables["segments"] = readFile("transcripts/"+meetingid+".txt")
    return render_template('annotator.html', data=template_variables)

@app.route('/music/<meetingid>')
def download_sound_file(meetingid):
    return send_file('audio/'+meetingid+'/'+meetingid+".wav")

这是我的目录结构：

.
├── app.py
├── app.wsgi
├── _templates
|   ├── annotator.html
|   └── ...
├── transcripts
|   ├── Bdb001.txt

|   |   ├── Bdb001.wav
|   |   ├── Bdb001.mp3
|   |   └── ...
|   └── ...

app.wsgi：

activate_this = '/home/ubuntu/meeting_data_parser/annotator/env2/bin/activate_this.py'
with open(activate_this) as f:
    exec(f.read(), dict(__file__=activate_this))

import sys
import logging

logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/html/annotator")

from app import app as application

Apache配置：

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html

    WSGIDaemonProcess annotator threads=5
    WSGIScriptAlias / /var/www/html/annotator/app.wsgi

    <Directory flaskproject>
        WSGIProcessGroup annotator
        WSGIApplicationGroup %{GLOBAL}
        Order deny,allow
        Allow from all
    </Directory>    


    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

以下是错误的堆栈跟踪：

Apache上的Flask：FileNotFoundError：[Errno 2]没有这样的文件或目录
