Look at the sentences:
Le professeur dit de ne pas courir
The teacher says not to run
Il est important de ne pas bouger.
It is important not to move.
Il m'a appris à ne pas avoir peur.
He taught me not to be scared.
J'espère ne pas faire d'erreurs.
I hope not to make a mistake.
Note that if a sentence has two verbs but it's the infinitive verb (a verb that's not conjugated) that requires negation, ne pas goes before the infinitive rather than around it.
Note: If there is a pronoun before the infinitive, ne pas precedes it.
Ma mère m'a dit de ne pas le faire
My mother told me not to do it
Je t'ai demandé de ne pas lui dire.
I asked you not to tell him.

The negation "ne pas" will come after the preposition "de", but in this case:
"J'espère ne pas faire D'erreurs."
the "d' " is not the preposition, but the partitive "des" which became d' because this is a negative sentence.
Think that you say "espérer quelque chose" and not "espérer DE quelque chose".
I hope that's helpful!
À bientôt !

why isn't it "Premiere erreur de ne pas faire" but is "Premieur erreur a ne pas faire"?

Bonjour Leah !
This is an excellent question.
The difference here relates to impersonal expressions.
Here's the rule:
- When you have a real subject, like "première erreur" - i.e. to do. - and that the infinitive is used intransitively (without a object), then the structure is:
[subject/adjective] + à + [infinitive]
La première chose à faire...
The first thing to do...
C'est bon à savoir.
That's good to know.
- When you have a *dummy* subject - i.e. it is to do - the structure is:
il est/c'est + [adjective] + de + [infinitive]
Il est difficile de parler. / C'est difficile de parler.
It's hard to talk.
Il est important de faire confiance à ses amis.
It's important to trust one's friends.
I hope that's helpful!
À bientôt !

Bonjour Helen !
Here it's not a case of impersonal expressions, but a case of reported (or indirect) speech, hence the use of de :
Je lui demande de venir. -> I ask him to come.
Bonne journée !
