I would suggest you tried another way of installing nodejs, like using <a href="https://github.com/creationix/nvm" rel="nofollow noreferrer">Node Version Manager</a>. 
It is really easy to use and lets you run multiple version of nodejs and npm dependencies on the same machine.

As it is <a href="https://docs.npmjs.com/getting-started/fixing-npm-permissions" rel="nofollow noreferrer">stated in npm documentation</a>, EACCESS errors usually go away with the following strategies:

<ol>
<li>Use a Version manager (like Node Version Manager)</li>
<li>Change nodejs default installation directory</li>
</ol>

Nodejs website installation package installed it almost like it expected a pc.
So we're seeing two issues here

<ul>
<li>Premission on directory it was installed, which can be fixed with <code>chmod</code></li>
<li>Location unknown, which can be fixed with <code>export</code></li>
</ul>

You can export by editing ~/.bash_profile
and adding

<pre><code>export PATH="[Enter your path here]:$PATH"
</code></pre>

But if you're new to this, I highly recommend to resort to helping installing software like <a href="https://changelog.com/posts/install-node-js-with-homebrew-on-os-x" rel="nofollow noreferrer">homebrew approach</a> very friendly mac installing/update for terminal. 

Will want to uninstall your current node if possible. 

Then it's

<pre><code>/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew update

brew doctor

export PATH="/usr/local/bin:$PATH"

brew install node

npm install -g @angular/cli@latest 
</code></pre>

If you're using an installation of Node and NPM based on Homebrew, your installation may not keep your globally installed packages in a predictable location (mine didn't).

<a href="http://codermem.com/javascript/angular/install-or-update-ngm-and-angular-on-mac-os/" rel="nofollow noreferrer">These steps</a> helped me ensure Angular CLI and other globally-installed packages land in a predictable location and now they work in my terminal.

Summary:

<ol>
<li>Delete any existing NPM packages:

<code>sudo rm -rf /usr/local/lib/node_modules</code></li>
<li>Delete your current installation of Node and NPM:

<code>brew uninstall node</code></li>
<li>Preconfigure NPM to install packages in a location under your home directory:

<code>echo prefix=~/.npm-packages &gt;&gt; ~/.npmrc</code></li>
<li>Add the new NPM packages location to your shell's search path:

<code>echo 'export PATH="$HOME/.npm-packages/bin:$PATH"' &gt;&gt; ~/.bash_profile</code></li>
<li>Quit and re-launch the Terminal app</li>
<li>Install Angular CLI in your fresh Node setup:

<code>npm install -g @angular/cli</code></li>
</ol>

Now the <code>ng</code> command should exist at <code>~/.npm-packages/bin/ng</code> and you should be able to run <code>ng --version</code> successfully.

You need to install @angular/cli globally NOT locally.
if you type:

<blockquote>
 npm install -g @angular/cli
</blockquote>

in terminal and you will get the error:
ng: command not found or different error, it's because you do not have access to the global directory of npm

The solution is:
just use sudo

<blockquote>
 sudo npm install -g @angular/cli
</blockquote>

Have you tried to check your <code>NODE_PATH</code> environment variable value ?

<pre><code>echo $NODE_PATH

If it's empty (and given your default location of installation in MacOS)
try to set it into:

<pre><code>export NODE_PATH=/usr/local/lib/node_modules:/usr/local/lib/node
</code></pre>

To make it more permanent put it inside your <code>~/.bash_profile</code>, then restart your terminal (otherwise <code>source ~/.bash_profile</code>)

Type the below commands:
<pre><code>nvm install stable

nvm install node

Check for the installed version of the node to verify the installation
node version
If you have node installed already then go for the below step:

Create a new project with:
<pre><code>ng new angularProject

ng server angularProject

I'm new to programming (and stackoverflow). I installed Angular using the following command in the terminal: npm install -g @angular/cli. I ran into an EACCESS error but <a href="https://docs.npmjs.com/getting-started/fixing-npm-permissions" rel="nofollow noreferrer">this</a> resolved it. Initially I was able to run the ng command. But after closing and reopening the terminal, the "ng: command not found" error happened. I removed Angular and reinstalled it. But that didn't help.
