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

Question

我的項目中有一個 .env 文件

SECRET_KEY="vvvvvvvtestvvvvv"

我運行pipenv shell

但我得到了一堆錯誤。

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

我究竟做錯了什么？

Answer 1

剛遇到這個問題。 可能是文件編碼問題。

嘗試在 Notepad++ 中打開 .env 文件，將編碼更改為 UTF-8，然后保存文件並重試。

Answer 2

可能您的SECRET_KEY在某處包含一個\\0並且您不能在環境變量中包含 NUL 字節。 只需將它從 env 文件中的SECRET_KEY中刪除，它應該可以工作。
