npm install -g less does not work: EACCES:权限被拒绝

我试图在phpstorm上设置较少，这样我就可以在保存时将.less文件编译为.css。我已经安装了node.js，下一步(根据这个https://www.jetbrains.com/webstorm/help/transpiling-sass-less-and-scss-to-css.html)是在终端上运行这个命令

npm install -g less

然而，当我这样做时，我得到这些错误

我在这里完全是个新手，不知道下一步该做什么。任何帮助都将非常感激!

其他回答

不建议使用sudo。它可能稍后给你许可问题。虽然上述方法可行，但我不赞成将root用户拥有的文件夹更改为用户可写的文件夹，尽管这可能只是多个用户的问题。为了解决这个问题，你可以使用“npm users”组，但这也会增加管理开销。查看这里的选项来处理文档中的权限: https://docs.npmjs.com/getting-started/fixing-npm-permissions

我选择选项2:

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. 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 If still show permission error run (mac os): sudo chown -R $USER ~/.npm-global

这适用于默认的ubuntu安装:
