pipenv (django) 中的 .env 文件 - ValueError: 嵌入的空字符

Question

I got a .env file inside my project

SECRET_KEY="vvvvvvvtestvvvvv"

I run pipenv shell

But I get like a bunch of errors.

PS S:\github\fozvi> pipenv shell
Loading .env environment variables…

What am I doing wrong?

Answer 1

Just ran into this problem. It may be a file encoding issue.

Try opening the .env file in Notepad++, change the encoding to UTF-8, then save the file and try again.

Answer 2

Probably your SECRET_KEY contains a \\0 somewhere and you can't have NUL bytes in an environment variable. Just remove it from your SECRET_KEY in the env file and it should work.
