                  @targos

                  Current Behavior:

                  Run npm install --force fails instead of ignoring upstream dependency conflict

                  Expected Behavior:

                  It should print a warning and continue with the installation.

                  Steps To Reproduce:

                  git clone https://github.com/targos/npm-force-peer-dep.git
                  cd npm-force-peer-dep
                  npm install --force
                  

                  Output:

                              [BUG] npm install --force fails for peerOptional conflicts #2504

                              Description

                              @targos

                              Current Behavior:

                              Run npm install --force fails instead of ignoring upstream dependency conflict

                              Expected Behavior:

                              It should print a warning and continue with the installation.

                              Steps To Reproduce:

                              git clone https://github.com/targos/npm-force-peer-dep.git
                              cd npm-force-peer-dep
                              npm install --force
                              

                              Output:
