Unable to install React Native cli on Mac using npm!
I have tried uninstalling both node and npm and trying the command npm install -g react-native-cli.
Also tried this,
"If you get an error like Cannot find module 'npmlog', try installing npm directly: curl -0 -L https://npmjs.org/install.sh | sudo sh"
Use sudo npm install -g react-native-cli
Also, you can use Yarn!
For reasons unknown to me, I haven't been able to update to the latest version of npm on macOS (it works fine on Windows). It displays no error, only 'updated 1 package'.
Using Node.js 8.11.1
node -v
v8.11.1
What version of npm do I have?
$ npm -v
5.6.0
I tried this...
$ npm i -g npm
+ npm#5.8.0
updated 1 package in 7.37s
And it fails to update.
$ npm -v
5.6.0
Where is npm?
$ which npm
/usr/local/bin/npm
So I try brew...
brew install npm
And it fails...
$ npm -v
5.6.0
*And then I tried this... *
npm install npm#latest -g
+ npm#5.8.0
updated 1 package in 7.618s
And it fails...
npm -v
5.6.0
With sudo:
sudo npm i -g npm
+ npm#5.8.0
updated 1 package in 7.794s
And it fails...
npm -v
5.6.0
This also fails...
sudo npm install npm#latest -g
I followed the directions found on this Q&A, completely removing npm and node from my system and reinstalling them from scratch, and it also fails to update.
Screenshot, per request:
Close the terminal, and then re-open the terminal and running:
$ npm -v
5.6.0
sudo twice:
$ sudo npm i -g npm
+ npm#5.8.0
updated 1 package in 7.478s
$ sudo npm i -g npm
+ npm#5.8.0
updated 1 package in 7.434s
Also fails:
$ npm -v
5.6.0
What did I miss? What's going on here?
This works on my mac.
Based on docs https://docs.npmjs.com/troubleshooting/try-the-latest-stable-version-of-npm :
npm install -g npm#latest
There is a note stated on the docs that depends on your installation method, you might addd some sudo.
Upgrading on *nix (OSX, Linux, etc.)
(You may need to prefix these commands with sudo, especially on Linux,
or OS X if you installed Node using its default installer.)
npm install -g npm#latest
works fine!!
and you can also replace the latest for specific versions
like
npm install -g npm#5.6.0
I hope it will help!!!
Perhaps you have already solved this, but here is what I found when I had exactly this issue. I had 2 versions of npm installed.
I verified this as follows:
grep \"version\" ~/.npm-packages/lib/node_modules/npm/package.json
"version": "6.2.0"
grep \"version\" /usr/local/lib/node_modules/npm/package.json
"version": "5.6.0",
I worked around the issue by updating the path in my bash profile, but would like to know why (how) I ended up with 2 versions. Here is the update:
tail -2 ~/.bash_profile
NPM_PACKAGES="${HOME}/.npm-packages"
PATH="$NPM_PACKAGES/bin:$PATH"
In my case, none of the previous answers worked. For me, a working solution was a simple, five-step process.
Make sure (the old version of) npm is installed.
npm -v
If npm is not installed, then install it on the Mac with Node.js.
Globally installed the desired version of npm.
npm install -g npm#latest
This command uses the old version of npm (installed by Node), to globally install the latest version of npm at ~/.npm-global/. Once installed, close and open a new terminal shell.
Remove the old version of npm installed by Node
rm -r /usr/local/lib/node_modules/npm/
Sometimes this doesn't work, so I had to go into finder to delete the /npm/ folder.
Make sure to set the correct path variable.
echo $PATH
If ~/.npm-global/bin does not show up between the colons, then update the path variable. Open up ~/.zshrc in a text editor and add the following line. If you don't use zsh, open the profile for your corresponding shell (i.e. ~/.bash_profile)
export PATH=$PATH:$HOME/.npm-global/bin
Save your changes and close the text editor.
Close and reopen the terminal shell and run npm -v to check that npm is correctly on the latest version.
The reason for updating the path variable is because the npm cli suggests you update npm with npm install -g npm which will install npm at a different location than where Node installs npm originally.
In my case, only the following has helped:
sudo rm -rf /usr/local/lib/node_modules
sudo rm -rf ~/.npm
brew uninstall --ignore-dependencies node
brew install node
EDIT NOV 21: These days, I bypass brew entirely and use "n":
https://www.npmjs.com/package/n
And so I can change between versions too.
I faced the same problem.
You might have already installed the npm version, and now it is time to point the new npm version install. You can do that by following below steps.
sudo nano /usr/local/lib/node_modules/npm/package.json
change "version" : "5.6.0" to "verison": "5.8.0"
In my case, I'm using nvm to manage different versions of node. In order to upgrade npm version, I have to
1 - Install the latest version of npm by navigating to your current
version of node
cd ~/.nvm/versions/node/v10.9.0
npm install npm
or you can probably use
nvm install-latest-npm
2 - Edit $PATH to point to your current version of node
NPM_PACKAGES="${HOME}/.nvm/versions/node/v10.9.0"
PATH="$NPM_PACKAGES/bin:$PATH"
On my macOS the homebrew-installed npm did not want to upgrade due to pre-existing link file. I ran the install with --force flag and now things are okay.
$ npm --version
6.14.16
$ npm install -g npm#8
npm ERR! EEXIST: file already exists, symlink ...
$ npm install -g --force npm#8
npm WARN using --force I sure hope you know what you are doing.
+ npm#8.19.2
$ npm --version
8.19.2
Note also that in my case, no 'sudo' was required, thanks to homebrew. To check if your npm is installed with homebrew, use brew list.
$ brew list | grep node
node#12
After a thorough analysis of 'Could not execute command lessc' i've successfully ran odoo (any version) on my command line with python virtual env. Am doing this to run odoo in command line
$ . {PATH_TO_VIRTUAL_ENV}/bin/activate (Running the script in the current shell)
$ cd {PATH_TO_ODOO_SOURCE}
$ ./odoo.py -c setup.cfg
And the above runs with proper UI.
Now when trying to run the same from eclipse throws me 'Could not execute command lessc'. I did the below to run code from eclipse
Installed pydev plugin in eclipse Mars
Configured Python interpreter (Given the virtual env python path here. i.e {PATH_TO_VIRTUAL_ENV}/bin/python)
Setup odoo source
Specified the new python interpreter on the project properties -> python interpretor
Created a new Run Configuration to run the source with the custom setup file and with the new interpretor
Kindly throw me light on places where i miss. Also i've gone through links on setting up python virtual env in eclipse. They all say the same thing still this lessc dependency is somehow not linked. Please comment if you require more info to identify the error. Thanks for your help! :)
FYI am using mac.
Update
For Shikhar (based on his answer)
This problem is related to your bad configuration of Nodejs and less on system.
Use commands below to resolve this -
wget -qO- https://deb.nodesource.com/setup | sudo bash -
then
brew install node
and finally
sudo npm install -g less less-plugin-clean-css
This will resolve the lessc command issue.
try this
sudo apt-get install node-clean-css
sudo apt-get install node-less
The solution:
sudo apt-get install node-clean-css
sudo apt-get install node-less
may work for Global system installation but if you are working within a virtualenv you may try this.
If somebody had the issue inside PyCharm wich was my case and nothing else works...
I leave my solution here:
First: I tried to check if node and npm exist inside my virtualenv: node -v and npm -v, not any of them... Second: I was using virtualenv, also when I ask inside my virtualenv with: which lessc . I didn't receive any response neither, so... I keep googling and found this post: How to install lessc and nodejs in a Python virtualenv?
In any case this was what I did on my virtualenv and the problem was solved:
MYVIRTUALENV/bin/activate # switch to my Python virtualenv first
pip3.7 install nodeenv # install nodeenv nodeenv was installed, in case you are using python 2.x use pip instead pip3
nodeenv --python-virtualenv # Use current python virtualenv
npm install -g less # install lessc in the virtualenv
npm install -g less-plugin-clean-css # also install this less-plugin...
then if I check with node -v and npm -v I get a proper response...
also get good response on: which lessc
After that no more nightmare with lessc execution in pycharm
bit of a macosx noob , trying to install grunt on my machine. I tried:
npm install grunt
It look like the files are downloaded properly but still getting the error.
When I do echo $PATH it does not look that the path is pointing to grunt. Do I have to install it from a certain directory? How can I fix this?
Edit
After I run :
npm install -g grunt-cli
This happens:
You have to do sudo npm install -g grunt-cli, then you can use grunt in your terminal
Hi guys could you help me? i've installed the latest version of node.js and installed cordova and ionic framework the problem starts is when i'm trying to run the ionic command, the console throw me the following message:
MacBook-Pro-de-Diego:~ diegochavez$ ionic start myApp
-bash: ionic: command not found
So then i looked for the root of my npm modules
MacBook-Pro-de-Diego:~ diegochavez$ npm root
/Users/diegochavez/node_modules
if you guys know something to fix this? Thanks in advance
First check if ionic is installed at path like /usr/local/lib/node_modules/ionic/bin/ionic. If it is there, you need to check the npm default global path.
Run command npm config get prefix to check the default path, it should be /usr/local. If it is not /usr/local, run command npm config set prefix /usr/local to set it. And then install again. Also see this answer
I having issue while running - sudo npm install -g gulp ionic with below version of node installed
node -v v0.10.15
npm -v 1.3.5
Error went way after I update node to latest version v0.10.26
The error you are getting is because ionic was not installed successfully. Trying updating node and run command as mentioned sudo npm install -g gulp ionic
Check where your npm folder is located. If your npm folder is located in $Home..then type this:
export PATH="$HOME/npm/bin:$PATH"
You need to run sudo npm install -g ionic from the command line.
