Hvis du er web- eller app-udvikler<\/a>, arbejder du sandsynligvis med en r\u00e6kke forskellige sprog<\/a>, frameworks<\/a> og milj\u00f8er. Udviklingsv\u00e6rkt\u00f8jer kan hj\u00e6lpe dig med at l\u00f8fte dine projekter til det n\u00e6ste niveau. Men efterh\u00e5nden som disse v\u00e6rkt\u00f8jer udvikler sig, er der en chance for, at du st\u00f8der p\u00e5 forhindringer som ERR_OSSL_EVP_UNSUPPORTED-fejlen.<\/p>\n

Heldigvis er oprindelsen af fejlen ERR_OSSL_OSSL_EVP_UNSUPPORTED ligetil. Desuden skyldes den en simpel uoverensstemmelse i din sikkerhedssoftware, s\u00e5 den er relativt nem at l\u00f8se.<\/p>\n

I dette indl\u00e6g vil vi diskutere ERR_OSSL_EVP_UNSUPPORTED-fejlen, og hvad der for\u00e5rsager den. Derefter viser vi dig, hvordan du kan rette den i tre forskellige scenarier. Lad os dykke direkte ned i det!<\/p>\n

<\/div><\/kinsta-auto-toc>\n

Hvad er fejlen ERR_OSSL_OSSL_EVP_UNSUPPORTED?<\/h2>\n

Lad os begynde med at se p\u00e5, hvordan fejlen ERR_OSSL_OSSL_EVP_UNSUPPORTED kan se ud i et udviklingsmilj\u00f8:<\/p>\n

\"Et
Fejlen ERR_OSSL_OSSL_EVP_UNSUPPORTED (Kilde:<\/strong> Stackoverflow<\/a>)<\/figcaption><\/figure>\n

Ved f\u00f8rste \u00f8jekast skiller ord som “UNSUPPORTED” og “ERR” sig ud, fordi de har indlysende betydninger. Men for at forst\u00e5 denne fejl korrekt skal vi fokusere p\u00e5 den del, hvor der st\u00e5r “OSSL”.<\/p>\n

Dette OSSL-tag repr\u00e6senterer den kryptografiske software OpenSSL<\/a>:<\/p>\n

\"OpenSSL
OpenSSL-webstedet<\/figcaption><\/figure>\n

OpenSSL er et softwarebibliotek med \u00e5ben kildekode, der anvender protokollerne Secure Sockets Layer (SSL) og Transport Layer Security (TLS)<\/a>\u00a0til at sikre sikker kommunikation i webudviklingsmilj\u00f8er.<\/p>\n

P\u00e5 samme m\u00e5de som ejere af websteder kan installere SSL-certifikater p\u00e5 websteder<\/a>, kan du bruge OpenSSL til at installere SSL-filer p\u00e5 din webserver. De giver dit udviklingsmilj\u00f8 et ekstra beskyttelseslag. Af denne grund er OpenSSL meget udbredt.<\/p>\n

Men da OpenSSL bruger kryptering, er det afh\u00e6ngig af visse hashing-algoritmer. N\u00e5r disse algoritmer udvikler sig med hver ny version af softwaren, kan der opst\u00e5 uoverensstemmelser med andre udviklingsv\u00e6rkt\u00f8jer. Det f\u00f8rer os til vores n\u00e6ste afsnit, hvor vi vil diskutere \u00e5rsagerne til fejlen ERR_OSSL_EVP_UNSUPPORTED.<\/p>\n\n

Hvad er \u00e5rsagen til fejlen ERR_OSSL_OSSL_EVP_UNSUPPORTED?<\/h2>\n

Nu hvor du ved en smule om OpenSSL og om, hvordan fejlen ERR_OSSL_OSSL_EVP_UNSUPPORTED ser ud, kan vi diskutere \u00e5rsagerne til fejlen. Som navnet antyder, afh\u00e6nger problemet af “underst\u00f8ttelsen” af OpenSSL-softwaren.<\/p>\n

Med andre ord indikerer fejlmeddelelsen, at noget i din webudviklingsstack ikke er kompatibelt med de OpenSSL-filer, du k\u00f8rer.<\/p>\n

Men hvorfor sker dette? Efterh\u00e5nden som hashing-algoritmer udvikler sig for at give \u00f8get sikkerhed, kan deres begr\u00e6nsninger blive strammere, og deres n\u00f8glest\u00f8rrelser kan \u00e6ndre sig. N\u00e5r OpenSSL’s hashing-algoritmer \u00e6ndres, kan der derfor opst\u00e5 uoverensstemmelser mellem dine udviklingsv\u00e6rkt\u00f8jer<\/a>.<\/p>\n

Selv om den utvivlsomt indeholder mange forbedringer, har udgivelsen af OpenSSL 3.0<\/a> medf\u00f8rt, at fejlmeddelelsen ERR_OSSL_EVP_UNSUPPORTED er blevet vist oftere:<\/p>\n

\"OpenSSL
OpenSSL 3.0-meddelelse<\/figcaption><\/figure>\n

Selv om udviklingsv\u00e6rkt\u00f8jer b\u00f8r l\u00f8se eventuelle inkompatibilitetsproblemer i deres opgraderinger, kan det v\u00e6re, at du arbejder med for\u00e6ldet software. Det kan v\u00e6re en pakke, et modul<\/a>, et framework, et bundle, et milj\u00f8 eller noget andet, der udl\u00f8ser fejlmeddelelsen.<\/p>\n

S\u00e5dan retter du fejlen ERR_OSSL_OSSL_EVP_UNSUPPORTED (3 almindelige tilf\u00e6lde)<\/h2>\n

Som vi har diskuteret, er for\u00e6ldet programmeringssoftware sandsynligvis det, der udl\u00f8ser ERR_OSSL_EVP_UNSUPPORTED-fejlen. Derfor vil vi vise dig, hvordan du kan opgradere tre forskellige udviklingsv\u00e6rkt\u00f8jer for at l\u00f8se problemet.<\/p>\n

Hvis du imidlertid ikke \u00f8nsker at opgradere dem af en eller anden grund, kan du blot aktivere OpenSSL 3.0 legacy-provideren<\/a> som en workaround. Det eneste du skal g\u00f8re er at bruge f\u00f8lgende kommando:<\/p>\n

--openssl-legacy-provider<\/code><\/p>\n

Ellers er her tre m\u00e5der at rette fejlen ERR_OSSL_EVP_UNSUPPORTED p\u00e5!<\/p>\n

1. Opgrader din Node.js-version<\/h3>\n

Node.js er et k\u00f8retidsmilj\u00f8 p\u00e5 tv\u00e6rs af platforme<\/a>, der bruges til at bygge server- og netv\u00e6rksprogrammer. Da det forenkler, fremskynder og forbedrer brugen af JavaScript, er det meget popul\u00e6rt.<\/p>\n

Men p\u00e5 grund af det store antal brugere, der har installeret Node.js<\/a>, er det almindeligt at finde fejlen ERR_OSSL_EVP_UNSUPPORTED i dette milj\u00f8<\/a>. Du kan endda st\u00f8de p\u00e5 ERR_OSSL_EVP_UNSUPPORTED i Angular<\/a> eller Next.js<\/a>, da Node.js er en foruds\u00e6tning for begge dele.<\/p>\n

Som en l\u00f8sning anbefaler vi, at du opgraderer din version af Node.js. Du skal bruge node package manager (npm)<\/a>\u00a0til denne proces. Hvis du ikke allerede har den installeret, kan du g\u00f8re det ved at indtaste f\u00f8lgende<\/a> i dit kommandolinjev\u00e6rkt\u00f8j:<\/p>\n

npm install -g n<\/code><\/p>\n

Derefter skal du kontrollere din aktuelle version af Node.js ved at indtaste denne kommando:<\/p>\n

node -v<\/code><\/p>\n

Endelig, hvis du opdager, at din version er for\u00e6ldet, skal du indtaste denne kommando:<\/p>\n

n latest<\/code><\/p>\n

Dette vil opgradere Node.js til den nyeste version. Derefter skal du kontrollere din version igen for at sikre, at opdateringen var vellykket. Forh\u00e5bentlig vil dette l\u00f8se fejlen ERR_OSSL_EVP_UNSUPPORTED.<\/p>\n

2. Opgrader din React.js-version<\/h3>\n

Sammen med Node.js er React.js en integreret del af masser af webudviklingsv\u00e6rkt\u00f8jer, s\u00e5som Gatsby<\/a>. Med det i tankerne vil vi ogs\u00e5 vise dig, hvordan du opgraderer din version af React.js<\/a>.<\/p>\n

Du kan g\u00f8re dette ved hj\u00e6lp af npm eller yarn-pakkeh\u00e5ndteringsprogrammet<\/a>. Med npm skal du blot indtaste f\u00f8lgende kommando:<\/p>\n

npm install react react-dom<\/code><\/p>\n

Alternativt kan du med yarn bruge denne:<\/p>\n

yarn add react react-dom<\/code><\/p>\n

S\u00f8rg derefter for at kontrollere din version for at sikre, at den nu er opdateret.<\/p>\n

3. Opgrader din Vue.js-version<\/h3>\n

Vue.js er en anden popul\u00e6r front-end JavaScript-ramme<\/a>. Derfor kan fejlen ERR_OSSL_OSSL_EVP_UNSUPPORTED forekomme, mens du arbejder i Vue.<\/p>\n

Igen kan du opgradere din rammes version ved hj\u00e6lp af npm eller yarn. Men f\u00f8rst skal du dog g\u00e5 i gang med at kontrollere din Vue.js-version i en af de to pakkeh\u00e5ndteringsprogrammer ved hj\u00e6lp af f\u00f8lgende kommando:<\/p>\n

vue --version<\/code><\/p>\n

Hvis du derefter vil opgradere Vue.js<\/a> med npm, skal du bruge f\u00f8lgende:<\/p>\n

update -g @vue\/cli<\/code><\/p>\n

Alternativt skal du bruge dette med yarn:<\/p>\n

global upgrade --latest @vue\/cli<\/code><\/p>\n

Husk, at begge disse kommandoer opgraderer den globale Vue CLI-pakke.<\/p>\n\n

Opsummering<\/h2>\n

Hvis du bruger OpenSSL til at sikre dine udviklingsprojekter, kan du st\u00f8de p\u00e5 fejlmeddelelsen ERR_OSSL_EVP_UNSUPPORTED. Dette kan l\u00e6gge en d\u00e6mper p\u00e5 dine fremskridt. Heldigvis kan du l\u00f8se dette irriterende problem p\u00e5 et par forskellige m\u00e5der.<\/p>\n

Afh\u00e6ngigt af din udviklingsstack kan du l\u00f8se fejlen ved at opgradere din version af Node.js, React.js eller Vue.js. Hvis det ikke virker, eller hvis du ikke \u00f8nsker at opgradere, kan du ogs\u00e5 bruge --openssl-legacy-provider<\/code> som en l\u00f8sning.<\/p>\n

Hvis du v\u00e6lger en p\u00e5lidelig hostingudbyder som Kinsta, er du mindre tilb\u00f8jelig til at st\u00f8de p\u00e5 problemer som ERR_OSSL_EVP_UNSUPPORTED-fejlen.
