Answer 1

Run these commands in a terminal window:

sudo chown -R $USER ~/.npm
sudo chown -R $USER /usr/lib/node_modules
sudo chown -R $USER /usr/local/lib/node_modules

Answer 2

I had this issue, I could fixed it by calling sudo on every global install. I wasn't ok with that.

I followed the n package installation advices to be able to install npm packages without sudo.

sudo chown -R $(whoami) /usr/local/bin /usr/local/lib /usr/local/include /usr/local/share

Answer of @jeduard didn't work for me.

Answer 3

Best way to solve your npm install -g issues:

https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally

This way, you will never need to use SUDO or change permissions .

Quoting :

1. Back up your computer.

2. On the command line, in your home directory, create a directory for global installations:

    mkdir ~/.npm-global

3. Configure npm to use the new directory path:

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

4. In your preferred text editor, open or create a ~/.profile file and add this line:

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

5. On the command line, update your system variables:

    source ~/.profile

Answer 4

Appending sudo before the npm install saved my day.Once you provide your system password, installation should finish smoothly

sudo npm install -g @angular/cli

Answer 5

Same problem. I reinstalled the latest version of node via https://nodejs.org/en/download/ instead of using terminal. This resolved the issue.

Answer 6

只需添加sudo ： sudo npm install -g @angular/cli

Answer 7

I had a similar issue when trying to install React -- issues with permissions being denied.

This is where SUDO can come in handy, it allows a permitted user to execute a command as the superuser or another user. Think of like "Run as Administrator" on Windows. If you type in the following command, it should allow you to access all of the needed folders with the proper elevated access.

sudo chown -R $(whoami) /usr/local/bin /usr/local/lib /usr/local/include /usr/local/share

Answer 8

如果您真的无法全局安装 NPM 模块（例如在某些公司笔记本电脑上），您可以将它们全部安装在某个地方的单个本地文件夹中，然后将 node_modules/.bin/ 的路径添加到您的 PATH 环境中。

Answer 9

ry appending sudo before whatever command you are trying.

like this : sudo npm install

Using sudo with a command in Linux/UNIX generally elevates your permissions to superuser levels. In Windows, the superuser account is usually called 'Administrator.' In Linux/Unix the superuser account is generally named 'root'.

The root user has permission to access, modify or delete almost any file on your computer. Normal user accounts can access, modify or delete many fewer files. The restrictions on a normal account protect your computer from unauthorized or harmful programs or users. Some processes require you to perform actions on files or folders you don't normally have permissions to access. Installing a program that everyone can access is one of these actions.

In your case, running the installation command with sudo gives you the permissions of the superuser, and allows you to modify files that your normal user doesn't have permission to modify.

Answer 10

I had the same issue.
type this cmd in terminal

sudo nautilus

after that, it opens another file manager that has root access

after that type

    sudo apt install nodejs 
    sudo apt install npm 
    sudo npm install -g npm@latest
    sudo npm install -g @angular/cli
    ng --version

Answer 11

我只是使用对我有用的sudo和 FWIW 运行安装命令:)

Answer 12

For macOS try to run -

sudo chown -R $USER ~/.npm
sudo chown -R $USER /usr/local/lib/node_modules
sudo chown -R $USER /usr/local/bin/

If this still doesn't work you might need to add sudo to the npm install command.

Answer 13

很简单，运行下面的命令
sudo chown -R $USER /usr/local/lib/node_modules

Answer 14

Try using on the terminal

su

It'll ask you for the password, then you can run the command above.
