如何卸载 package.json (NPM) 中列出的所有依赖项? [英] How do you uninstall all dependencies listed in package.json (NPM)?

问题描述

如果我在我的应用程序根目录中定义了 package.json 文件并运行 npm install -g 它将安装 package.json 中定义的所有依赖项，全局.

If I have a package.json file defined in my application root and run npm install -g it will install all the dependencies defined in package.json, globablly.

然而，这似乎不能反过来.

However, this doesn't seem to work in reverse.

如果我在我的应用程序根目录中执行 npm uninstall -g 它会抛出一个错误，期望我向它传递一个包名.

If I do npm uninstall -g in my application root it throws an error, expceting me to pass it a package name.

这不应该也卸载我安装的相同软件包吗?

Shouldn't this also uninstall the same packages I installed?

我做错了吗?

推荐答案

如果使用 Bash，只需切换到包含 package.json 文件的文件夹并运行以下命令:

If using Bash, just switch into the folder that has your package.json file and run the following:

for package in `ls node_modules`; do npm uninstall $package; done;

对于全局安装的包，切换到 %appdata%/npm 文件夹(如果在 Windows 上)并运行相同的命令.

In the case of globally-installed packages, switch into your %appdata%/npm folder (if on Windows) and run the same command.

此命令与 npm 3.3.6(节点 5.0)中断.我现在正在使用以下 Bash 命令，该命令已映射到我的 .bashrc 文件中的 npm_uninstall_all:

npm uninstall `ls -1 node_modules | tr '/\n' ' '`

注意:它会从 package.json 和 package-lock.json 中删除所有依赖项列表，使 npm install 变得无用，因为没有列出要安装的依赖项.

Note: It would remove all dependencies list from package.json and package-lock.json rendering npm install useless as there would be no dependencies listed to be installed.
