即使使用 sudo，Yeoman 也会给出权限错误

Question

我正在关注 this tutorial 并安装了 Yeoman 和 Azure 的生成器。

所以，当我这样做时：sudo yo azuresfcontainer，它给了我以下错误：

/usr/local/lib/node_modules/yo/node_modules/fast-glob/out/providers/reader-sync.js:45
            throw err;
            ^

我哪里错了？

我认为您没有做错任何事，看起来 yeoman 的依赖破坏了 yeoman。它是 yeoman-environment 依赖项，这个问题已经打开：https://github.com/yeoman/environment/issues/97 复制粘贴下面的问题：

While running yo, the following error occurs: Error: EACCES: permission denied, scandir '/usr/sbin/authserver (MacOS / High Sierra)

Culprit is here:

  // Adds support for generator resolving when yeoman-generator has been linked
  if (process.argv[1]) {
        paths.push(path.join(path.dirname(process.argv[1]), '../..'));
  }

inside getNpmPaths(). My yo is at /usr/local/bin/yo, and this adds the whole /usr directory to the search path => globby.sync inside resolver.findsGeneratorIn will throw if some directories are not user readable.

Something like this fixes the issue:

try {
      modules = modules.concat(globby.sync(
        ['generator-*', '@*/generator-*'],
        {cwd: root, onlyFiles: false, absolute: true}
      ));
} catch(err) {
     debug( 'Could not access %s (%s)', root, err); 
}

我可以通过将全局包安装到不同的文件夹来解决这个问题。 https://docs.npmjs.com/getting-started/fixing-npm-permissions

To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, it will be a hidden directory on your home folder.

Back-up your computer before you start.

Make a directory for global installations:

mkdir ~/.npm-global 

Configure npm to use the new directory path:

npm config set prefix '~/.npm-global'

Open or create a ~/.profile file and add this line:

export PATH=~/.npm-global/bin:$PATH

Back on the command line, update your system variables:

source ~/.profile

Test: Download a package globally without using sudo.

npm install -g jshint

Instead of steps 2-4, you can use the corresponding ENV variable (e.g. if you don't want to modify ~/.profile):

NPM_CONFIG_PREFIX=~/.npm-global
