"ERRORE: root: non è stato trovato il codice per l'hash md5" quando si utilizzano comandi hg mercurial

Quando hgprovo ad usare qualsiasi comando Mercurial sulla console, continuo a ricevere questo errore. Ho installato Python usando Homebrew e sto eseguendo Mac OS Catalina v. 10.15.1.

Qualsiasi riferimento sarebbe apprezzato. Ecco l'errore che sto ricevendo:

Ho anche provato a seguire le istruzioni su questo problema, ma nessuna delle soluzioni sembra funzionare

brew link openssl --force
Warning: Refusing to link macOS-provided software: openssl@1.1
If you need to have openssl@1.1 first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc

For compilers to find openssl@1.1 you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"

For pkg-config to find openssl@1.1 you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"

La corsa brew reinstall python@2non ha funzionato per i miei ambienti virtuali Python 2.7 esistenti. Al loro interno c'erano ancora ERROR:root:code for hash sha1 was not founderrori.

Ho riscontrato questo problema dopo l'esecuzione brew upgrade openssl. Ed ecco la soluzione:

$ ls /usr/local/Cellar/openssl

...che mostra

1.0.2t

Secondo la versione esistente, eseguire:

$ brew switch openssl 1.0.2t

...che mostra

Cleaning /usr/local/Cellar/openssl/1.0.2t
Opt link created for /usr/local/Cellar/openssl/1.0.2t

Successivamente, esegui il seguente comando in un virtualenv Python 2.7:

(my-venv) $ python -c "import hashlib;m=hashlib.md5();print(m.hexdigest())"

...che mostra

d41d8cd98f00b204e9800998ecf8427e

Niente più errori.

Gestito per risolvere questo problema prima scollegando openssl

brew unlink openssl

E quindi reinstallare Python

brew reinstall python@2

Ho anche notato che durante l'esecuzione di 'brew doctor' c'era un avviso relativo a una cartella openssl che si trova in / usr / local / include / node /. Ho cancellato questa cartella prima di eseguire i comandi sopra (non sono sicuro se correlato)

Il caso per me è che quando installo le dipendenze di un'app Web Django, rovina l'ambiente. Quando scrivo cd, mostra lo stesso errore.

Il problema era la openssllibreria, non riesce a trovare quelli corretti.

Se sei su Macintosh, puoi digitare

ls /usr/local/Cellar/openssl

per vedere tutte le versioni,

brew switch openssl 1.0.XXXX

per scegliere la versione di openssl disponibile.

Quindi l'errore scompare :)

Quando importerei l'hashlib vedrei un messaggio di errore che indica che l'hash md5 non è stata trovata.

Sono stato in grado di risolvere questo problema prima scollegando openssl: brew unlink openssl

Quindi ho disinstallato Python 2.7 usando MacPorts: sudo port Uninstall Python27

Quindi ho installato Python 2.7 usando MacPorts: sudo port installa python27

Ora l'importazione di hashlib funziona :)

Disinstallare semplicemente python2

$ brew uninstall python@2

Se c'è qualche errore:

$ brew uninstall --ignore-dependencies python@2
