问题描述

我正在尝试在phpstorm上减少设置,以便在保存时将.less文件编译为.css.我已经安装了node.js和下一步(根据此 https://www.jetbrains.com/webstorm/help/transpiling-sass-less-and-scss-to-css.html )正在终端中运行此命令

I'm trying to set up less on phpstorm so I can compile .less files to .css on save. I have installed node.js and the next step (according to this https://www.jetbrains.com/webstorm/help/transpiling-sass-less-and-scss-to-css.html) is running this command in the terminal

npm install -g less

但是,当我这样做时,我会得到这些错误

However when I do this I get these errors

我是一个完全菜鸟,不知道下一步该怎么做.任何帮助将不胜感激!

I'm a complete noob here and not sure what to do next. Any help would be very appreciated!

推荐答案

不建议使用sudo.稍后可能会给您权限问题. 尽管上述方法有效,但我不喜欢将root拥有的文件夹更改为对用户可写,尽管这可能只是多个用户的问题. 要解决此问题,您可以将一个组与"npm users"一起使用,但这也增加了管理开销. 请参阅此处以获取处理文档中权限的选项: https://docs.npmjs.com/getting-started/fixing-npm-permissions

Using sudo is not recommended. It may give you permission issue later. While the above works, I am not a fan of changing folders owned by root to be writable for users, although it may only be an issue with multiple users. To work around that, you could use a group, with 'npm users' but that is also more administrative overhead. See here for the options to deal with permissions from the documentation: https://docs.npmjs.com/getting-started/fixing-npm-permissions

我会选择选项2:

为了最大程度地减少权限错误的可能性,您可以将npm配置为 使用其他目录.在这个例子中,它将是一个隐藏的 目录放在您的主文件夹中.

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.

为全局安装创建目录:

 mkdir ~/.npm-global

配置npm以使用新的目录路径:

Configure npm to use the new directory path:

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

打开或创建〜/.profile文件并添加以下行:

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

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

返回命令行,更新系统变量:

Back on the command line, update your system variables:

 source ~/.profile

测试:不使用sudo全局下载软件包.

Test: Download a package globally without using sudo.

npm install -g jshint

如果仍然显示权限错误,请运行(mac os):

If still show permission error run (mac os):

sudo chown -R $USER ~/.npm-global   

这适用于默认的ubuntu安装:

This works with the default ubuntu install of:

sudo apt-get install nodejs npm

如果您希望在版本管理方面具有更大的灵活性,我建议您使用nvm: https://github.com/creationix/nvm

I recommend nvm if you want more flexibility in managing versions: https://github.com/creationix/nvm

在MacOS上使用brew,如果您使用的是最新版本的npm,它应该在没有sudo的情况下也可以正常使用. 享受:)

On MacOS use brew, it should work without sudo out of the box if you're on a recent npm version. Enjoy :)
