npm 安装：错误：EACCES：权限被拒绝，mkdir

Question

I attempted to do a sudo npm install -g appium on Mac OS 10.12.5.

I get this error:

info Chromedriver Install Installing Chromedriver version '2.30' for platform 'mac' and architecture '64'

info Chromedriver Install Opening temp file to write chromedriver_mac64 to...

Error: EACCES: permission denied, mkdir

'/usr/local/lib/node_modules/appium/node_modules/appium-chromedriver/2017820-44752-12jfqpb.z2hd'

npm ERR! code ELIFECYCLE

npm ERR! errno 1

npm ERR! appium-chromedriver@3.0.1 install: node install-npm.js npm ERR! Exit status 1 npm ERR!

this is not a dup question, as this install attempt was with sudo, as the other one was not.

Answer 1

sudo npm install -g appium --unsafe-perm=true --allow-root

Worked for me

Answer 2

you are using npm so you have to use

sudo npm install --unsafe-perm
In unsafe mode with every command you run
hopefully, it will help

Answer 3

I reinstalled Node/NPM. Problem solved.

Answer 4

The -g option means install globally . When packages are installed globally , EACCES permission errors can occur.

Consider setting up npm to operate globally without elevated permissions. See Resolving Permission Errors for more information.

Option 1

The best way to avoid permission issues is to reinstall NodeJS and npm using a node version manager.

1. Install nvm

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash

You can close and reopen the terminal ou just open another terminal and check if nvm is installed properly with this command: command -v nvm .

2. To download and install the latest LTS release of NodeJS, run:

nvm install --lts

3. Set the newly installed NodeJS as the default environment:

nvm alias default lts/*

Option 2 (Does not apply for windows)

Change the owner of npm's directories to the current user:

sudo chown -R $(your_user) /usr/local/{lib/node_modules,bin,share}
sudo chown -R $(your_user) ~/.npm ~/.npmrc
