Answer 1

Give this a try:

• composer require google/apiclient:2.0.0-RC6

  • fetching version by tag name 2.0.0-RC6

• composer require google/apiclient:2.0.*@dev

  • version from 2.0.* range with dev stability

---

Example run for composer require google/apiclient:2.0.*@dev :

./composer.json has been created

Answer 2

I just had a similar issue with another Google package when running composer update :

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - googleads/googleads-php-lib dev-experimental requires google/auth 0.7 -> satisfiable by google/auth[v0.7].
    - googleads/googleads-php-lib dev-experimental requires google/auth 0.7 -> satisfiable by google/auth[v0.7].
    - Conclusion: don't install google/auth v0.7
    - Installation request for googleads/googleads-php-lib dev-experimental -> satisfiable by googleads/googleads-php-lib[dev-experimental].

I had no conflicting packages. The solution was to:

• Temporarily remove the googleads/googleads-php-lib line from composer.json
• Run composer update
• Reintroduce the line in composer.json
• Run composer update again

This worked for me.

I once had this same problem while developing an application that needed Google Library. There is a package you have installed that required another version of the Google Library dependency package, in my case it was firebase/php-jwt (v4.0.0) whereas the Google Library required v3.0.0 .
