根据官网教程 https://certbot.eff.org/lets-encrypt/ubuntuxenial-nginx 安装必须软件后

执行 $ sudo certbot --nginx 后报错：

Saving debug log to /var/log/letsencrypt/letsencrypt.log
An unexpected error occurred:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe6 in position 44: ordinal not in range(128)
Please see the logfiles in /var/log/letsencrypt for more details.

报错文件的内容是：

服务器是 ubuntu 16.04 nginx

没怎么搞过 python，看这最后一行报错好像是跟 python 的默认编码有关？参考一下 SO 的这个
https://stackoverflow.com/questions/21129020/how-to-fix-unicodedecodeerror-ascii-codec-cant-decode-byte


根本就不知道改哪个文件。。。

acme.sh please

什么意思？

他的意思 https://github.com/Neilpang/acme.sh

File "/usr/lib/python3/dist-packages/certbot_nginx/nginxparser.py", line 123, in load
return loads(_file.read())
File "/usr/lib/python3.5/encodings/ascii.py", line 26, in decode
return codecs.ascii_decode(input, self.errors)[0]
肯定是…… nginx 配置文件里有中文…

要把配置文件中的中文全部去掉？

你加 certonly 好了，有了证书自己改 nginx 的配置


配置文件全部去掉中文，报错依旧。

certbot certonly 还是同样的报错。。。

错误提示中“ ordinal not in range(128)” 代表你的配置文件中使用了不在普通 ASCII 范围内，使用了特殊字符串，去掉


额比如呢？？这个我不知道有哪些。配置文件略多。

查 ASCII 表，'0xe6' 代表 'æ'，搜索你的文件中是否有这个字符

太感谢了。。
