Pycharm在Django服务器调试模式下返回非ASCII错误，在正常运行模式下可以正常工作。

Question

我有一个Django服务器在本地运行了一段时间。今天突然在调试模式下出现错误，但在正常模式下可以正常工作。

我尝试在manage.py中包含utf-8，但仍然看到错误。

pydev debugger: process 10424 is connecting

Connected to pydev debugger (build 192.6603.34)
pydev debugger: process 10425 is connecting

I expect it to run on debug mode. it already bloked me 1/2 day. Please help if you already have seen this issue or know how to fix this.

我尝试重新安装了PyCharm，但我不知道这个非ASCII字符在哪里。 - Raj

• Python版本: 2.7.16
• PyCharm版本: 2019.2.3 (社区版)

我的问题也是如此。

pydev应该解析执行python脚本文件到“--file”参数。但当fork一个子进程时，它会将python二进制文件添加到“--file”参数中。
天哪，这浪费了我很多时间来处理。但根本原因仍未找到。

您可以在您的pydev_monkey.py文件中，在PyCharm安装目录下，以下面的代码：

from _pydevd_bundle.pydevd_command_line_handling import setup_to_argv

下方添加：

args = args[1:]

这可以暂时使Debug功能正常运作。

例如，在我的电脑上，路径为/Applications/PyCharm CE.app/Contents/helpers/pydev/_pydev_bundle/pydev_monkey.py。

尝试使用noreload运行，似乎在自动重新加载程序生成子进程时失败了，因为pydev尝试将python可执行文件解释为脚本。

Answer 3

使用noreload运行可以解决“SyntaxError: Non-ASCII character '\xcf' in file”问题。当我在正常模式下运行时，还有另一个问题。 输入图像描述 SyntaxError: Non-ASCII character '\xe6'

为了定义源代码编码，必须将魔术注释放置到源文件中，作为文件的第一或第二行（例如/Applications/PyCharm.app/Contents/plugins/python/helpers/pydev/_pydev_bundle/pydev_monkey.py），如下所示： "# --coding:utf-8 -- "
