错误：EACCES，甚至在使用sudo之后拒绝了权限？ [英] Error: EACCES, permission denied even after using sudo?

问题描述

我正在尝试设置一个Chrome扩展程序，该扩展程序将自动保存使用检查元素功能对我的网站所做的更改。这个想法是，你将能够对网站进行实时更改，而不必回到IDE来保存更改并重新上传等等。该扩展名称为DevTools Autosave。我一直在按照这个网站的指示。我试图在Mac上安装它。

我已经安装了node.js和扩展。当我到达指令中涉及在终端中运行哪些命令的部分时，我尝试了在npm install -g autosave命令之前使用和不使用sudo命令，但是我总是得到此错误：

 错误：EACCES，权限在Function.startup.resolveArgv0（node.js：815：23）处被拒绝

任何人都知道我可以如何解决这个问题？我找不到任何人有这个问题，我现在已经在几个不同的论坛，但无法找到解决方案。

解决方案

您有两种选择：修复您的 npm setup，所以你可以使用 npm -g ，或者在本地安装 autosave 。

要在本地安装（即在当前目录中的 node_modules 中），运行 npm install autosave （没有 -g ）。然后，您可以运行 ./ node_modules / .bin / autosave 或 ./ node_modules / autosave / bin / autosave 开始 autosave 。

要解决您的 npm 你可以在没有root权限的情况下使用 -g （推荐）：

在你的home dir中（假设 / Users / Brent / ），创建一个名为 .npmrc 的文件，其中包含以下内容：

  cache = /Users/Brent/.npm/cache 
 globalconfig = /Users/Brent/.npm/npmrc 
 globalignorefile = / Users / Brent /.npm/npmignore 
 prefix = /Users/Brent/.npm 
  

然后添加〜/ .npm / lib / node_modules 添加到您的 NODE_PATH 中，例如通过在 .bashrc （假设你的shell是bash）中放置以下代码以允许找到模块，并追加〜/ .npm / bin 到 PATH ，所以你可以运行任何已安装的二进制文件（即从任何地方运行 autosave`）：

export NODE_PATH = $ HOME / .npm / lib / node_modules
export PATH = $ PATH：$ HOME / .npm / bin


（对 .bashrc 的更改仅在您生效时生效加载shell或使用。〜/ .bashrc ;如果你想在不重新加载shell的情况下使用新的设置，只需运行该行（ export ... ）在您当前的shell中）。

I am trying to set up a chrome extension that will automatically save the changes I make to my website with the inspect element feature. The idea is that you'll be able to make real time changes to the website without having to go back into the ide to save the changes and re-upload and everything. The extension is called DevTools Autosave. I've been following the instructions from this site. I'm trying to install this on a mac.

I've installed node.js and the extension already. When I got to the part in the instructions where it talks about which commands to run in the terminal I've tried both with and without the "sudo" in front of the "npm install -g autosave" command but I always get this error:

Error: EACCES, permission denied

Anyone know how I can fix this? I can't find anyone that is having this problem and I've been on a few different forums now but can't find a solution. Thanks in advance.

解决方案

You have two options: Either fix your npm setup, so you can use npm -g, or install autosave locally.

To install locally (i.e. in node_modules within your current directory), run npm install autosave (without -g). Then you can run ./node_modules/.bin/autosave or ./node_modules/autosave/bin/autosave to start autosave.

To fix your npm setup, so you can use -g without root permissions (recommended):

In your home dir (assuming /Users/Brent/), create a file called .npmrc with the following content:

cache = /Users/Brent/.npm/cache
globalconfig = /Users/Brent/.npm/npmrc
globalignorefile = /Users/Brent/.npm/npmignore
prefix = /Users/Brent/.npm

And add ~/.npm/lib/node_modules to your NODE_PATH, e.g. by putting the following in .bashrc (assuming that your shell is bash) to allow the modules to be found, and append ~/.npm/bintoPATHso you can run any installed binary (i.e. runautosave` from anywhere):

export NODE_PATH=$HOME/.npm/lib/node_modules
export PATH=$PATH:$HOME/.npm/bin

(changes to .bashrc only take effect when you load the shell, or use . ~/.bashrc; if you want to use the new setup without reloading the shell, just run that line (export ...) in your current shell).
