Migrations exceeded the block limit with a gas value you set

Question

Please help me solve this error while migrating truffle:

1_initial_migration.js
======================
   Deploying 'Migrations'
   ----------------------
Error:  *** Deployment Failed ***
"Migrations" exceeded the block limit (with a gas value you set).
   * Block limit:  2582365
   * Gas sent:     20000000
   * Try:
      + Sending less gas.
      + Setting a higher network block limit if you are on a
        private network or test client (like ganache).

I am also getting this error.

Answer 1

In the error you have posted, in this part:

 * Block limit:  2582365
 * Gas sent:     20000000

you can see that gas is more than block limit. To solve this, you have to reduce the gas in truffle.js file.

How to go about this?

---

Like I mentioned in the answer,open your truffle.js file with a text editor and decrease the gas value.

---

Block Limit is changing on every migration. that's why I can't fix the gas accordingly.

Did you try setting gas to a lower value? Until and unless gas is less than block limit, I think it should be fine.
