我有一个.key文件

openssl rsa -text -in file.key

我明白了

unable to load Private Key
140000419358368:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:703:Expecting: ANY PRIVATE KEY

我也有一个.cer文件,当我这样做

openssl x509 -text -in file.cer

我明白了

unable to load certificate
140387178489504:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:703:Expecting: TRUSTED CERTIFICATE

但如果在这里指出我运行命令,如:

openssl x509 -text -inform DER -in file.cer

我明白了

Certificate:
    Data:
        Version: 3 (0x2)
        Some more information
        ...
-----BEGIN CERTIFICATE-----
MIIEdDCCA1ygAwIBAgIUMjAwMDEwMDAwMDAxMDAwMDU4NjcwDQYJKoZIhvcNAQEF
...
-----END CERTIFICATE-----

但这似乎与关键不起作用,因为当我跑

openssl rsa -text -inform DER -in aaa010101aaa__csd_10.key

我明白了

我试图在virtualenv中安装lxml sudo pip install lxml,sudo pip install --upgrade lxml但在两种情况下都得到以下内容:

我正在使用SpeechRecognition python 库设置声音识别器。

到目前为止，这是我的代码：

#!/usr/bin/env python3

import speech_recognition as sr

r = sr.Recognizer('es-MX')

with sr.Microphone() as mic:
    audio = r.listen(mic)

print(r.recognize(audio))

在跑步时我得到
