Question

我认为这里的主要问题是使用mutt命令： mutt -s "Title" -a $file -- "$address" < $DIR/message.txt。如果我从脚本中删除它，就没有错误，所以也许有人会知道发生了什么。

这是一个使用flask的python应用程序。这是一个有问题的方法：

@app.route('/send', methods=['POST'])
def send():
start_date = '2016-10-20'
end_date = '2016-10-28'
path = os.path.dirname(os.path.realpath(__file__))
script = path + '/script.sh'
address = 'my@mail.com'
subprocess.check_call([script, start_date, end_date, address])
return json.dumps({
    'message': 'Your message is sent!'
})

子流程运行脚本：

#!/bin/bash
start_date="$1"
end_date="$2"
address="$3"
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
$file="My_super_file"
out=$(R -e "rmarkdown::render('$DIR/generate_file.Rmd', output_file = $file)")
mutt -s "Title" -a $file -- "$address" < $DIR/message.txt

生成文件时，我收到这样的错误：

[2016-10-28 16:03:06,857] ERROR in app: Exception on /send [POST]

bash脚本中的Mutt在python（flask）应用程序中引发错误
