Não é possível instalar o Python no Windows 8

Question

Recentemente, decidi atualizar do Python 2.7 para o Python 3.4 no meu laptop com Windows 8. Então, eu desinstalei o Py2.7, baixei o arquivo .msi do site do python e o executei. Descobri que todos os instaladores que eu tentei tanto para 3.4.1 quanto para 3.4.0 me davam um erro dizendo que parte do instalador não funcionava. A mensagem de erro exata é "Há um problema com este pacote do Windows Installer. Um programa executado como parte da instalação não foi concluído conforme o esperado. Entre em contato com a equipe de suporte ou o fornecedor do pacote." Eu nunca tive esse tipo de problema antes e certamente não com Python. Alguém sabe de uma boa maneira de tentar depurar isso? Ele está persistindo em tantos instaladores que tenho certeza que tem que ser algo no meu sistema.

EDIT: Obrigado pela dica sobre o arquivo de log. É muito grande (maior do que posso postar neste site ~ 320k caracteres). Aqui está o pouco logo depois que diz "erro fatal". Isto é a partir da execução do código sugerido no instalador para 3.4.1 64 bits.

Answer 1

Como esse problema vem do pip vem com o instalador do python 3.4, você pode simplesmente desmarcar a opção de instalação do pip no instalador e tentar instalar o pip manualmente mais tarde.

    

Answer 2

Eu tive o mesmo erro ou pelo menos semelhante, mas não consegui encontrar uma solução. Eu tinha acabado de desinstalar o Python 3.4.1 e estava tentando instalar o Python 3.4.2.

Eu localizei três problemas diferentes no meu ambiente, mas o # 3 é o que realmente resolveu meu problema. Os dois primeiros itens não fizeram muita diferença para a minha situação, apenas os incluí como opções / ideias adicionais para outros (particularmente ao instalar uma segunda versão do Python, etc.).

1. Variáveis de ambiente que sobraram. Eu tinha variáveis de ambiente do conjunto de instalação 3.4.1. Ao instalar várias versões, isso pode causar um erro durante a instalação. Você pode precisar remover essas variáveis de ambiente.

   

2. PATHdosistema.OPythonaindaestavanosistemaPATH.Novamente,aoinstalarváriasversões,issopodecausarumerroduranteainstalação.VocêpodeprecisarremoveressasentradasdoseuPATH.

3. O problema real: Custom open/command no Registro. Eu tenho essa entrada do registro aqui, (além de adicionar .PY ao PATHEXT envar), para que eu possa executar programas em Python usando apenas app.py , em vez de ter que digitar PYTHON app.py .

   

O problema era que a nova versão do Python estava sendo parcialmente instalada e então tentava executar alguns comandos do Python durante a instalação. Devido ao meu registro personalizado, ele estava tentando executar o código Python usando o caminho antigo para python.exe, que foi, naturalmente, desinstalado. Então, falharia toda vez.

Assim, a remoção do comando / abertura personalizada permitiu que a instalação fosse bem-sucedida. Eu adicionei de volta, uma vez que a instalação foi concluída.

Algumas coisas a serem observadas. Eu não teria o problema se não estivesse mudando o local de instalação. E eu poderia ter apenas atualizado a entrada open / command para apontar para o novo local, em vez de removê-lo e adicioná-lo novamente.

    

Answer 3

Hooray, Finalmente depois de lats de investigação eu encontro a solução, Vá para o caminho do sistema e remova qualquer endereço de caminho que aponte para python27 ou qualquer outra versão e execute o instalador msi.

    

Answer 4

Não tenho uma resposta concreta aqui, mas aqui estão alguns passos de depuração do MSI bastante genéricos que podem restringir o problema:

Primeiro, precisamos gerar um log da instalação. O comando msiexec /i installer.msi /l*v log.txt pode fazer isso.

Depois de ter o log, a primeira coisa que você pode fazer é pesquisar Error ou FatalError (como você fez). Observe que isso ocorre no log após as ações de retrocesso, portanto, você precisará rolar para trás em muitas páginas de FileRemove , ComponentUnregister , etc. Na verdade, você pode encontrar para InstallFinalize e olhando diretamente acima disso para ser mais útil (ignore a primeira ocorrência perto do topo).

Aqui estão as linhas interessantes do seu registro de erros:

MSI (s) (60:80) [12:14:22:868]: Executing op: ActionStart(Name=UpdatePip,,)
Action 12:14:22: UpdatePip. 
MSI (s) (60:80) [12:14:22:868]: Executing op: CustomActionSchedule(Action=UpdatePip,ActionType=3090,Source=C:\Python34\python.exe,Target=-m ensurepip -U --default-pip,)
CustomAction UpdatePip returned actual error code 3 (note this may not be 100% accurate if translation happened inside sandbox)
MSI (s) (60:80) [12:14:23:212]: Note: 1: 1722 2: UpdatePip 3: C:\Python34\python.exe 4: -m ensurepip -U --default-pip 
MSI (s) (60:80) [12:14:23:212]: Note: 1: 2262 2: Error 3: -2147287038 
Error 1722. There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor.  Action UpdatePip, location: C:\Python34\python.exe, command: -m ensurepip -U --default-pip 
MSI (s) (60:80) [12:14:25:627]: Note: 1: 2262 2: Error 3: -2147287038 
MSI (s) (60:80) [12:14:25:627]: Product: Python 3.4.1 -- Error 1722. There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor.  Action UpdatePip, location: C:\Python34\python.exe, command: -m ensurepip -U --default-pip 

Este é um erro interessante, e eu não estou completamente certo porque python -m ensurepip -U --default-pip estaria falhando. Eu sugiro, talvez, tentar pegar uma cópia portátil ou compilar a partir da fonte e, em seguida, executar o comando manualmente, para ver se você pode obter mais informações. Caso contrário, você pode entrar em contato com os mantenedores por meio do IRC , uma lista de discussão ou algum outro método.

E, claro, se você descobrir por que postar uma auto-resposta aqui para ajudar os outros!

    

Answer 5

Para mim, o problema foi que o instalador do Python encontrou a versão errada do hashlib no meu sistema, o que quebrou a etapa 'ensurepip' na instalação, que infelizmente não reporta um erro útil. A geração do log msiexec me ajudou a rastrear esse erro.

Parece que o instalador deve ter mais cuidado ao usar seu próprio hashlib.

Este bug está relacionado, e esta página é o que me ajudou a descobrir que era um hashlib estranho (embora meu problema fosse no Windows).
