Om du \u00e4r webb- eller apputvecklare<\/a> s\u00e5 arbetar du f\u00f6rmodligen med en m\u00e4ngd olika spr\u00e5k<\/a>, ramverk<\/a> och milj\u00f6er. Utvecklingsverktyg kan hj\u00e4lpa dig att ta dina projekt till n\u00e4sta niv\u00e5. N\u00e4r dessa verktyg utvecklas finns det dock en chans att du st\u00f6ter p\u00e5 hinder som felet ERR_OSSL_EVP_UNSUPPORTED.<\/p>\n

Som tur \u00e4r \u00e4r ursprunget till felet ERR_OSSL_EVP_UNSUPPORTED okomplicerat. Dessutom orsakas det av en enkel inkonsekvens i din s\u00e4kerhetsprogramvara. Som ett resultat s\u00e5 \u00e4r det relativt enkelt att l\u00f6sa.<\/p>\n

I det h\u00e4r inl\u00e4gget diskuterar vi felet ERR_OSSL_EVP_UNSUPPORTED och vad som orsakar det. Vi visar dig sedan hur du \u00e5tg\u00e4rdar det i tre olika scenarier. L\u00e5t oss k\u00f6ra ig\u00e5ng direkt!<\/p>\n

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

Vad \u00e4r felet ERR_OSSL_EVP_UNSUPPORTED?<\/h2>\n

L\u00e5t oss b\u00f6rja med att ta en titt p\u00e5 hur felet ERR_OSSL_EVP_UNSUPPORTED kan se ut i en utvecklingsmilj\u00f6:<\/p>\n

\"Felet
Felet ERR_OSSL_EVP_UNSUPPORTED (K\u00e4lla:<\/strong> Stackoverflow<\/a>)<\/figcaption><\/figure>\n

Vid f\u00f6rsta anblicken sticker ord som ”UNSUPPORTED” och ”ERR” ut eftersom de har en uppenbar betydelse. Men f\u00f6r att f\u00f6rst\u00e5 felet ordentligt m\u00e5ste vi fokusera p\u00e5 den del d\u00e4r det st\u00e5r ”OSSL”<\/p>\n

Denna OSSL-tagg representerar kryptografi-applikationen OpenSSL<\/a>:<\/p>\n

\"Webbplatsen
Webbplatsen f\u00f6r OpenSSL<\/figcaption><\/figure>\n

OpenSSL \u00e4r ett programvarubibliotek med \u00f6ppen k\u00e4llkod. Det anv\u00e4nder protokollen Secure Sockets Layer (SSL) och Transport Layer Security (TLS)<\/a> f\u00f6r att garantera en s\u00e4ker kommunikation i webbutvecklings-milj\u00f6er.<\/p>\n

P\u00e5 samma s\u00e4tt som webbplats-\u00e4gare kan installera SSL-certifikat p\u00e5 webbplatser<\/a> kan du exempelvis anv\u00e4nda OpenSSL f\u00f6r att installera SSL-filer p\u00e5 din webbserver. De ger d\u00e4refter din utvecklingsmilj\u00f6 ett extra skyddslager. Av denna anledning anv\u00e4nds OpenSSL i stor utstr\u00e4ckning.<\/p>\n

Men eftersom OpenSSL anv\u00e4nder kryptering \u00e4r det beroende av vissa hash-algoritmer. N\u00e4r dessa algoritmer utvecklas med varje ny version av programvaran kan det uppst\u00e5 inkonsekvenser med andra utvecklingsverktyg. Det leder oss till n\u00e4sta avsnitt, d\u00e4r vi kommer att diskutera orsakerna till felet ERR_OSSL_EVP_UNSUPPORTED.<\/p>\n\n

Vad orsakar felet ERR_OSSL_EVP_UNSUPPORTED?<\/h2>\n

Nu vet du lite om OpenSSL och hur felet ERR_OSSL_EVP_UNSUPPORTED. L\u00e5t oss diskutera dess orsaker. Som namnet antyder beror problemet p\u00e5 ”st\u00f6det” f\u00f6r OpenSSL-programvaran.<\/p>\n

Med andra ord visar felmeddelandet att n\u00e5got i din webbutvecklings-stack inte \u00e4r kompatibelt med OpenSSL-filerna som du k\u00f6r.<\/p>\n

Men varf\u00f6r h\u00e4nder detta? N\u00e4r hash-algoritmer utvecklas f\u00f6r att ge en \u00f6kad s\u00e4kerhet kan deras begr\u00e4nsningar sk\u00e4rpas och deras nyckelstorlekar \u00e4ndras. N\u00e4r OpenSSL’s hash-algoritmer \u00e4ndras kan det d\u00e4rf\u00f6r uppst\u00e5 inkonsekvenser mellan dina utvecklingsverktyg<\/a>.<\/p>\n

OpenSSL 3.0 har utan tvekan medf\u00f6rt m\u00e5nga f\u00f6rb\u00e4ttringar. Efter lanseringen av OpenSSL 3.0<\/a> har felmeddelandet ERR_OSSL_EVP_UNSUPPORTED dock dykt upp allt oftare:<\/p>\n

\"Meddelande
Meddelande om OpenSSL 3.0<\/figcaption><\/figure>\n

\u00c4ven om utvecklingsverktygen b\u00f6r l\u00f6sa eventuella inkompatibilitets-problem i sina uppgraderingar kan det exempelvis h\u00e4nda att du arbetar med en f\u00f6r\u00e5ldrad programvara. Det kan vara ett paket, en modul<\/a>, ett ramverk, ett paket, en milj\u00f6 eller n\u00e5got annat som utl\u00f6ser felmeddelandet.<\/p>\n

S\u00e5 h\u00e4r \u00e5tg\u00e4rdar du felet ERR_OSSL_EVP_UNSUPPORTED (3 vanliga fall)<\/h2>\n

Som vi diskuterade \u00e4r det troligtvis en f\u00f6r\u00e5ldrad programvara som utl\u00f6ser felet ERR_OSSL_EVP_UNSUPPORTED. Vi ska d\u00e4rf\u00f6r visa dig hur du kan uppgradera tre olika utvecklingsverktyg f\u00f6r att l\u00f6sa problemet.<\/p>\n

Om du inte vill uppgradera dem av n\u00e5gon anledning kan du helt enkelt aktivera OpenSSL 3.0 legacy provider<\/a> som en l\u00f6sning. Allt som du beh\u00f6ver g\u00f6ra \u00e4r att anv\u00e4nda f\u00f6ljande kommando:<\/p>\n

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

Annars finns det tre s\u00e4tt att \u00e5tg\u00e4rda felet ERR_OSSL_EVP_UNSUPPORTED!<\/p>\n

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

Node.js \u00e4r en plattformsoberoende k\u00f6rtidsmilj\u00f6<\/a> som anv\u00e4nds f\u00f6r att bygga server- och n\u00e4tverksapplikationer. Eftersom den exempelvis f\u00f6renklar, snabbar upp och f\u00f6rb\u00e4ttrar anv\u00e4ndningen av JavaScript \u00e4r den mycket popul\u00e4r.<\/p>\n

P\u00e5 grund av det stora antalet anv\u00e4ndare som har installerat Node.js<\/a> \u00e4r det dock vanligt att felet ERR_OSSL_EVP_UNSUPPORTED hittas i denna milj\u00f6<\/a>. Du kan dessutom st\u00f6ta p\u00e5 ERR_OSSL_EVP_UNSUPPORTED i Angular<\/a> eller Next.js<\/a> eftersom Node.js \u00e4r en f\u00f6ruts\u00e4ttning f\u00f6r b\u00e5da.<\/p>\n

Som en l\u00f6sning rekommenderar vi att du uppgraderar din version av Node.js. Du m\u00e5ste anv\u00e4nda node package manager (npm)<\/a> f\u00f6r den h\u00e4r processen. Om du inte redan har den installerad kan du g\u00f6ra detta genom att skriva in f\u00f6ljande<\/a> i ditt kommandoradsverktyg:<\/p>\n

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

Kontrollera sedan din nuvarande version av Node.js genom att skriva in det h\u00e4r kommandot:<\/p>\n

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

Om du uppt\u00e4cker att din version \u00e4r f\u00f6r\u00e5ldrad, ange det h\u00e4r kommandot:<\/p>\n

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

Detta kommer att uppgradera Node.js till den senaste versionen. Kontrollera sedan din version igen f\u00f6r att se om uppdateringen lyckades. F\u00f6rhoppningsvis kommer detta att l\u00f6sa felet ERR_OSSL_EVP_UNSUPPORTED.<\/p>\n

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

Tillsammans med Node.js \u00e4r React.js en integrerad del av m\u00e5nga verktyg f\u00f6r webbutveckling, till exempel Gatsby<\/a>. Med detta i \u00e5tanke ska vi \u00e4ven visa dig hur du uppgraderar din version av React.js<\/a>.<\/p>\n

Du kan exempelvis g\u00f6ra detta med hj\u00e4lp av npm eller pakethanteraren yarn<\/a>. Med npm anger du helt enkelt f\u00f6ljande kommando:<\/p>\n

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

Alternativt kan du anv\u00e4nda detta f\u00f6r yarn:<\/p>\n

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

Se sedan till att kontrollera att din version \u00e4r uppdaterad.<\/p>\n

3. Uppgradera din version av Vue.js<\/h3>\n

Vue.js \u00e4r ett annat popul\u00e4rt JavaScript-ramverk f\u00f6r frontend<\/a>. D\u00e4rf\u00f6r kan felet ERR_OSSL_EVP_UNSUPPORTED dyka upp n\u00e4r du arbetar i Vue.<\/p>\n

\u00c5terigen kan du uppgradera ramverkets version med hj\u00e4lp av npm eller yarn. Men f\u00f6rst kan du g\u00e5 vidare och kontrollera din version av Vue.js i n\u00e5gon av pakethanterarna med hj\u00e4lp av f\u00f6ljande kommando:<\/p>\n

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

F\u00f6r att uppgradera Vue.js<\/a> med npm anv\u00e4nder du sedan f\u00f6ljande:<\/p>\n

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

Alternativt, med garn, m\u00e5ste du anv\u00e4nda detta:<\/p>\n

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

T\u00e4nk p\u00e5 att b\u00e5da dessa kommandon uppgraderar det globala Vue CLI-paketet.<\/p>\n\n

Sammanfattning<\/h2>\n

Om du anv\u00e4nder OpenSSL f\u00f6r att s\u00e4kra dina utvecklingsprojekt kan du st\u00f6ta p\u00e5 felmeddelandet ERR_OSSL_EVP_UNSUPPORTED. Detta kan hindra dina framsteg. Som tur \u00e4r kan du l\u00f6sa det h\u00e4r irriterande problemet p\u00e5 n\u00e5gra olika s\u00e4tt.<\/p>\n

Beroende p\u00e5 din utvecklingsstack kan du l\u00f6sa felet genom att uppgradera din version av Node.js, React.js eller Vue.js. Om detta inte fungerar, eller om du inte vill uppgradera, kan du dessutom anv\u00e4nda --openssl-legacy-provider<\/code> som en l\u00f6sning.<\/p>\n
