Got the same problem (node v10.3.0, ionic 3.13.0). This worked :
- Delete
package-
lock.json
, - Delete
node_modules
folder, - Run
npm install
again.
Solution 2 - Angular
try
sudo rm -rf package-lock.json node_modules
sudo npm cache clean --force
npm i --unsafe-perm node-sass
Solution 3 - Angular
Just Try with this command hope it will very helpful. it's working for me
sudo npm install -g [email protected] --unsafe-perm=true --allow-root
Solution 4 - Angular
rolling back to node v10.17.0
fixed the problem to me.
You can use nvm to do so:
> nvm install 10.17.0
> nvm use 10.17.0
> node -v
10.17.0
Solution 5 - Angular
I also had to face the same problem with node v12.16.3
.
-
Remove
node-sass
dependency from yourpackage.json
if it is mentioned in yourdependencies
.This will allow npm to install other required dependencies without any disruption. -
Delete
package-lock.json
file andnode_modules
folder from your project. -
Force clean the entire NPM cache by using following comand.
npm cache clean --force
-
Re-Install all the dependencies.
npm install
-
Now you can install
node-sass
.npm i node-sass
Solution 6 - Angular
[email protected] cannot be installed on node 8
Please update either node-sass or node version compatible
Go to https://github.com/sass/node-sass/releases to check which fits for you
Solution 7 - Angular
use this flag --unsafe-perm=true
sudo npm i gulp-sass -ES --unsafe-perm=true
Solution 8 - Angular
Uninstall current npm and install lower versions, it is a common error if version didn't match, downgrading node/npm will mostly fix this kind of issues
npm install -g npm@4.6.1
Solution 9 - Angular
After uninstalling node-sass try cleaning your npm cache. After that try installing node-sass again.
npm cache clean && npm install node-sass
Solution 10 - Angular
The minimum version of node-sass that supports Node 8 is 4.5.3. You'll need to upgrade your node-sass or downgrade your Node version. Ionic may also have separate issues since it isn't a tested platform with node-sass.
Solution 11 - Angular
You should try to install SASS.
I remember havign this issue in AngularJS with compass, I had to install it with Ruby to make it work. This was 3 years ago, so I'm not sure this would be the solution, but it doesn't cost anything except time to try, right ?
Solution 12 - Angular
Install the higher version of node-sass
npm install node-sass@4.13.1
Solution 13 - Angular
I had the same issue with a new install with Keystone.js. I was able to get pass this issue by removing Node Sass from package.json and running npm install again. Being that the package wasn't listed under node modules. And it worked fine after that.
Solution 14 - Angular
I needed to take the following steps to "resolve" this problem:
- Create folder at the root:
mkdir ~/safe_node_module
; - Download package
wget -q https://github.com/sass/node-sass/releases/download/v4.13.0/linux-x64-72_binding.node
and then send to the folder created in step 1; - Set the export environment variable
export SASS_BINARY_PATH=/home/ronaldaraujo/safe_node_module/linux-x64-72_binding.node
; - Install packages normally
npm i
;
Solution 15 - Angular
Solved this by force installing node-sass locally: npm install -f node-sass
I was pretty sure I knew what I was doing... this
Solution 16 - Angular
I'm trying to do npm install
in the ionic project and an error appears
> Failed at the [email protected] postinstall script.
The following steps worked for me ionic project
Remove npm
than run the following commands
> npm i > > npm install @ionic/app-scripts@latest--unsafe-perm=true --allow-root
Solution 17 - Angular
Sometime unable to download file win32-x64-79_binding.node due to your proxy restrict to download so plase follow this below link set them manually. https://github.com/sass/node-sass/issues/2773
Solution 18 - Angular
This works for me on Windows running Node.js version v14.17.3
npm install -g [email protected] --unsafe-perm=true --allow-root --force
Note: My node-sass version was [email protected]. But the above command will work for other versions too. Just replace the node-sass version number in the above command with your required node-sass version.
Solution 19 - Angular
The following steps worked for me
npm install -g [email protected] --unsafe-perm=true --allow-root
npm cache clean
npm install
