[PhongGCS]

Dear author,

that are
"stem-press/stem:0.7.20"
"stem-press/mail-template": "0.3.1",
"stem-press/stem-content": ">=0.4.4"

It show below error.

duncan3dc/blade[4.4.0, ..., 4.6.0] require illuminate/view >=5.5,<5.9 -> satisfiable by illuminate/view[v5.5.0, ..., 5.8.x-dev].
- Root composer.json requires roave/security-advisories dev-master -> satisfiable by roave/security-advisories[dev-master].
    - stem-press/stem 0.7.20 requires duncan3dc/blade ^4.4 -> satisfiable by duncan3dc/blade[4.4.0, ..., 4.11.0].
    - duncan3dc/blade[4.9.0, ..., 4.11.0] require illuminate/view ^6.0 || ^7.0 -> satisfiable by illuminate/view[v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev].

    - nesbot/carbon 2.x-dev is an alias of nesbot/carbon dev-master and thus requires it to be installed too.
    - You can only install one version of a package, so only one of these can be installed: nesbot/carbon[dev-master, 1.20.0, ..., 1.39.1, 2.0.0-beta.1, ..., 2.57.0].
    - stem-press/stem 0.7.20 requires nesbot/carbon ^1.21 -> satisfiable by nesbot/carbon[1.21.0, ..., 1.39.1].
    - Conclusion: don't install nesbot/carbon 1.22.0 (conflict analysis result)
