Npm install 忽略版本号中的波浪号 (~) [英] Npm install ignores tilde (~) in version number

问题描述

我想安装 1.8.x 版本的软件包，并且能够稍后在 >=1.8.0 <1.9.0 范围内自动更新此依赖项.

I would like to install 1.8.x version a package, and be able to later automatically update this dependency inside the >=1.8.0 <1.9.0 range.

我尝试运行此命令:

npm install example-package@~1.8 --save

不幸的是，它将此记录添加到我的 package.json 中:

Unfortunately it adds this record to my package.json:

"example-package" : "^1.8.0"

但我想要的是:

"example-package" : "~1.8.0"

如何使用 npm install 做到这一点，而无需手动编辑 package.json 文件?

How is it possible to do it with npm install, without manually edit the package.json file?

推荐答案

semver 前缀由 save-prefix 配置.默认值是一个插入符号 (^)，您可以通过运行以下命令进行检查 npm config 命令:

The semver prefix is defined by the save-prefix config. The default value is a caret (^) which you can check by running the following npm config command:

npm config get save-prefix

不幸的是，npm install 命令没有指定选项这个，所以你需要做的是:

Unfortunately, the npm install command has no option to specify this, so what you'll need to do is:

1. 通过运行将 save-prefix 值设置为波浪号 (~):

1. Set the save-prefix value to a tilde (~) by running:

npm config set save-prefix="~"

运行以下命令安装您的软件包:

Install your package by running:

npm i example-package@1.8.0 --save

注意: 波浪号 (~) 不得包含在安装命令中.

Note: The tilde (~) must not be included in the install command.

最后，通过运行将 save-prefix 值设置回它的默认值，即插入符号 (^):

Finally, set the save-prefix value back to it's default, i.e. a caret (^) by running:

npm config delete save-prefix

注意:如果您希望以后的所有 npm install 都使用波浪号 (~)，您就不会执行最后一步前缀而不是插入符号 (^).

Note: You wouldn't do this last step if you wanted all future npm install's to use the tilde (~) prefix instead of a caret (^).

以上步骤会在package.json中添加如下记录:

The above steps will add the following record in package.json:

"example-package" : "~1.8.0"

_{注意波浪号 ~ 而不是默认的插入符号 ^}

_{Note the tilde ~ instead of the default caret ^}

您可以使用 && 运算符将上述命令组合成一个复合命令.例如:

You can utilize the && operator to combine the aforementioned commands into a compound command. For instance:

npm config set save-prefix="~" && npm i example-package@1.8.0 --save && npm config delete save-prefix
