Python 无法在Windows上生成sqlcipher3

构建sqlcipher后，在根文件夹中复制sqlite3.c和sqlite3.h，我正在尝试构建（在Windows 10上，Python 3.9.0）：

这里是Blob.c中的行（第638行是

模块名称“.Blob”，

）：

有人能帮我继续吗？

谢谢

我今天也遇到了同样的问题，设置几乎完全相同。为了成功编译sqlcipher3，我需要做两个修改：

模块名称

预编译器定义的内容在

setup.py

的第38行中设置。此处调用的函数

quote_参数

，用于区分Windows和其他平台。在Windows上，引号字符用反斜杠转义。至少对于MSVC2019而言，这似乎是不正确的。要修复它，只需删除第35行的Windows特定内容

OpenSSL的库名称在版本1.1.0中已更改。如果您使用的是较新版本，则可能必须将库名称从

libeay32.lib

更改为

libcrypto.lib

，或在系统上调用库的任何内容（第132行）。此外，您可能需要设置环境变量

OPENSSL\u CONF

，以帮助构建脚本在系统上查找OPENSSL

---

有了这两个小的修改，构建过程运行得很好。

谢谢！很好用！我很高兴能帮上忙！非常感谢。很好用！我很高兴能帮上忙！
