yarn install无法在规定位置生成node_module文件夹

Question

问题描述：

已经在项目package.json所在根目录 ./my_project 的 .yarnrc文件 中规定好了安装位置：

> --install.modules-folder "./media/node_modules"
--add.modules-folder "./media/node_modules"
registry "https://registry.yarnpkg.com"

但yarn install 运行约1-2分钟后过后无法在 ./my_project/media/node_modules文件夹生成所需要的依赖，该文件夹是空的。
cmd运行过程如下：

> (ENV) C:\my_project\my_project>yarn install

操作环境、软件版本等信息:

win 10命令行，yarn 1.22.19

尝试过的解决方法：

1. 清除缓存yarn cache clean, 删除yarn.lock和package-lock.json文件，再试。
   运行1-2分钟后，目标文件夹node_modules依然是空的
2. 使用npm i命令。
   npm i 运行结束后在 ./my_project根目录下直接生成了node_modules文件夹，里面安装的依赖齐全。但也无法生成在 ./my_project/media内。

我想要达到的结果：

使用yarn 1.22.19，yarn install命令能将需要的依赖下载在 ./media/node_modules 中

Answer 1

可以尝试以下步骤，以确保 yarn 可以正确地将依赖项安装在指定的目录中：

确保您在运行 yarn install 命令时，当前工作目录是 my_project/media，而不是 my_project。

删除 my_project/media 下的 node_modules 文件夹（如果有的话），以便重新安装依赖项。

在 my_project/media 目录中创建一个 package.json 文件，可以使用 yarn init 命令来创建。

在 package.json 文件中添加您需要安装的依赖项

{
  "dependencies": {
    "dependency1": "^1.0.0",
    "dependency2": "^2.0.0"
  }
}

这里的 "dependency1" 和 "dependency2" 是您需要安装的依赖项的名称和版本号。

运行 yarn install 命令，确保您在 my_project/media 目录中运行该命令。Yarn 将自动将依赖项安装在 my_project/media/node_modules 目录中。

如果这些步骤不起作用，您可以尝试更新 Yarn 版本，或者使用 npm 安装依赖项。
