Erro ao instalar o Chocolatey no Win10

Qual o erro exato que você se refere? Todos os avisos são sobre erros que são seguros de ignorar. Você consegue executar o comando no PowerShell após a tentativa de instalação? Lembre-se de reiniciar o PowerShell após instalar o Chocolatey.

Ian,

Eu me refiro a mensagem abaixo.

WARNING: You can safely ignore errors related to missing log files when upgrading from a version of Chocolatey less than 0.9.9. 'Batch file could not be found' is also safe to ignore. 'The system cannot find the file specified' - also safe. AVISO: Not setting tab completion: Profile file does not exist at 'C:\Users\diego\OneDrive\Documentos\WindowsPowerShell\Microsoft.PowerShell_profile.ps1'.

Após a instalação eu reinicio o powershell e entro no cmd para executar o chocolatey. Digito "choco" e aparece a mensagem abaixo.

Acabo de instalar o Chocolatey via PowerShell no Windows 10 pelo comando:

iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex

E recebi a seguinte resposta (bem similar a sua):

Acrescento que o software está funcionando normal, pois ao executar o comando Chocolatey no PS recebo a resposta:

Chocolatey v0.10.3

Estás executando o PowerShell via administrador? Poderia checar suas variáveis de ambientes e olhar a correspondente a do chocolatey? Execute também 'chocolatey' no PS, pode ser um problema na variável de ambiente.

Ian,

Fiz a instalação seguindo a sua, e consegui.

PS C:\WINDOWS\system32> choco Chocolatey v0.10.3

Obrigado, Amigo!

Por nada!
