我在package.json中添加了两个库

  "devDependencies": {
    ...
    "react-dom/test-utils": "*",
    "react-test-renderer/shallow": "*"
  },

如react docs所建议,以与React生态系统的版本16兼容.

运行npm install –verbose后,我得到了：

18 verbose node v8.5.0
19 verbose npm  v5.3.0
20 error code EINVALIDPACKAGENAME
21 error Invalid package name "react-dom/test-utils": name can only contain URL-friendly characters
22 verbose exit [ 1, true ]

另外尝试通过cli将其安装为devDependency也会出现此错误：

npm ERR! Error while executing:
npm ERR! /usr/bin/git ls-remote -h -t ssh://git@github.com/react-dom/test-utils.git
npm ERR! 
npm ERR! Permission denied (publickey).
npm ERR! fatal: Could not read from remote repository.
npm ERR! 
npm ERR! Please make sure you have the correct access rights
npm ERR! and the repository exists.
npm ERR!

我如何解决这个问题,以使那些程序包可在代码中引用？

解决方法:

只需添加react-dom作为依赖项：npm install –save-dev react-dom

当您导入react-dom / test-utils时,它的意思是“从react-dom包中的test-utils文件夹/文件中导入”.
