npm install fails "invalid version"
the version number can only be like \d+\.\d+\.\d+
so \d+\.\d+.\d+.\d+
is not valid. so "1.0.0.0" is not valid and and "1.0.0" is. But check the link below for a more accurat description.
This works:
package.json
{
"name": "version-sample",
"version": "1.0.0",
"dependencies": {
"sample" : "*"
}
}
The full documentation is located here https://semver.org/ (including a proper regex
"1.0" is not a valid version as defined by Semantic Versioning. Changing it to "1.0.0" should solve your issue.
