Question

我写了Cargo.toml的依赖项：

[dependencies ]
opencv = {version = "0.26", default-features = false, features = ["opencv-41"]}

一行以上可以通过编译。

我想分开依赖关系的行。

上述解决方案。

我参考此解决方案来编写我的依赖项：

[dependencies ]
opencv = """\{version = "0.26", \
default-features = false, \
features = ["opencv-41"] \
}"""

但是编译器抛出错误：

$ cargo build                                          [±master ●]

error: failed to parse manifest at /home/curlywei/WorkSpace/rust/testcargo/Cargo.toml

Caused by:
  failed to parse the version requirement { version = "0.26", default-features = false, features = ["opencv-41"] } for dependency opencv

Caused by:
  the given version requirement is invalid

我该怎么办？

您的链接包含多行字符串的示例，而不是表。在TOML中，内联表可能不包含换行符。

相反，TOML spec建议使用常规表：

[dependencies.opencv]
version = "0.26"
default-features = false
features = ["opencv-41"]

关于Cargo.toml依赖项中的toml换行符
