安裝rails 顯示安裝 Puma 失敗,gem install puma -v '5.3.1' --source 'https://rubygems.org/

更新日期:

版本不一定會是 5.3.1,顯示哪個版本就執行哪個版本

所以就照著他說的

 

gem install puma -v '5.3.1' --source 'https://rubygems.org/

 

執行這個指令即可

 

如果成功的話,再進去專案裡面執行 bundle install 即可

 

如果失敗,顯示

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

 

error: implicit declaration of function 'SSL_CTX_get0_param'

is invalid in C99 [-Werror,-Wimplicit-function-declaration]

    X509_VERIFY_PARAM *param = SSL_CTX_get0_param(ctx);

                               ^

mini_ssl.c:242:32: note: did you mean 'SSL_CTX_set1_param'?

 

請參考:

gem install puma 失敗,error: implicit declaration of function 'SSL_CTX_get0_param', did you mean 'SSL_CTX_set1_param'?
