我尝试使用 gem install pg 但它似乎不起作用。

gem install pg 给出此错误

我遇到了这个问题，这对我有用：

安装 postgresql-devel 包，这将解决 pg_config 丢失的问题。

问题是 gem 依赖性，因此在安装 pg 之前请确保您已经安装了“libpq-dev”

Ubuntu 系统：

sudo apt-get install libpq-dev

RHEL 系统：

yum 安装 postgresql-devel

Mac：

酿造安装postgresql

Issue is gem dependency so before installing pg make sure you have installed "libpq-dev"

Ubuntu systems:

sudo apt-get install libpq-dev

RHEL systems:

yum install postgresql-devel

@Winfield 说的：

pg gem 需要 postgresql 客户端库进行绑定。此错误通常意味着它找不到您的 Postgres 库。您可能没有安装它们，或者您可能需要将 --with-pg-dir= 传递到您的 gem 安装。

不仅如此，您只需要 --with-pg-config= 即可安装它。

在 Mac 上

如果您还通过 Mac 上的网站捆绑包安装了 postgres，那么它将位于 /Applications/Postgres.app/Contents/Versions/9.3/bin 等位置。

因此，要么在 gem 安装中传递它：

gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.3/bin/pg_config

或者正确设置 PATH。由于这可能太多，暂时设置 PATH：

export PATH=%PATH:/Applications/Postgres.app/Contents/Versions/9.3/bin/

@Winfield said it:

The pg gem requires the postgresql client libraries to bind against. This error usually means it can't find your Postgres libraries. Either you don't have them installed or you may need to pass the --with-pg-dir= to your gem install.

More than that, you only need --with-pg-config= to install it.

On a Mac

If, by any chance, you also installed postgres through the website bundle on mac, it will be on somewhere like /Applications/Postgres.app/Contents/Versions/9.3/bin.

So, either you pass it on the gem install:

gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.3/bin/pg_config

Or you set the PATH properly. Since that might be too much, to temporarily set the PATH:

export PATH=%PATH:/Applications/Postgres.app/Contents/Versions/9.3/bin/

我没有安装 postgresql，所以我只是

sudo apt-get install postgresql postgresql-server-dev-9.1

在 Ubuntu 12.04 上安装它。

这解决了它。

更新：

使用最新版本：

sudo apt-get install postgresql-9.3 postgresql-server-dev-9.3

I hadn't postgresql installed, so I just installed it using

sudo apt-get install postgresql postgresql-server-dev-9.1

on Ubuntu 12.04.

This solved it.

Update:

Use the latest version:

sudo apt-get install postgresql-9.3 postgresql-server-dev-9.3

如果您在 Mac 上使用 Postgres.app，您可以像这样一劳永逸地解决此问题：

首先 gem uninstall pg，然后编辑您的 ~/. bash_profile 或 ~/.zshrc 文件或等效文件并添加：

# PostgreSQL bin path
export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.4/bin

然后 bundle install 和 gem install pg 应该都按预期工作。

If you are using Postgres.app on Mac, you may resolve this issue once and for all like this:

First gem uninstall pg, then edit your ~/.bash_profile or ~/.zshrc file or equivalent and add:

# PostgreSQL bin path
export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.4/bin

Then bundle install and gem install pg should both work as expected.

  • Ubuntu 20.10 (pop!_os)

  • Postgresql 12

卸载并重新安装 postgresql-client libpq5 libpq-dev

sudo apt remove postgresql-client libpq5 libpq-dev
sudo apt install postgresql-client libpq5 libpq-dev

然后再次安装 pg gem，指向 /usr/lib 以查找 pg 库：

gem install pg  --   --with-pg-lib=/usr/lib

输出（在上一个命令之后您应该看到的内容）：

Building native extensions with: '--with-pg-lib=/usr/lib'
This could take a while...

  • Postgresql 12

Uninstall and then reinstall postgresql-client libpq5 libpq-dev

sudo apt remove postgresql-client libpq5 libpq-dev
sudo apt install postgresql-client libpq5 libpq-dev

Then install the pg gem again pointing at /usr/lib to find the pg library:

gem install pg  --   --with-pg-lib=/usr/lib

Output (what you should see after the previous command):

无论您运行什么操作系统，请查看“Makefile”的日志文件以了解发生了什么，而不是盲目安装东西。

在我的情况下，MAC OS，日志文件在这里：

/Users/za/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/extensions/x86_64-darwin-15/2.3.0-static/pg-1.0.0/mkmf.log

日志表明无法创建 make 文件，原因如下：

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers

在 mkmf.log 中，您将看到它无法找到完成构建所需的库。

checking for pg_config... no
Can't find the 'libpq-fe.h header
blah blah

运行 "brew install postgresql" 后，我可以看到所有必需的库都在那里：

za:myapp za$ cat /Users/za/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/extensions/x86_64-darwin-15/2.3.0-static/pg-1.0.0/mkmf.log | grep yes
find_executable: checking for pg_config... -------------------- yes
find_header: checking for libpq-fe.h... -------------------- yes
find_header: checking for libpq/libpq-fs.h... -------------------- yes
find_header: checking for pg_config_manual.h... -------------------- yes
have_library: checking for PQconnectdb() in -lpq... -------------------- yes
have_func: checking for PQsetSingleRowMode()... -------------------- yes
have_func: checking for PQconninfo()... -------------------- yes
have_func: checking for PQsslAttribute()... -------------------- yes
have_func: checking for PQencryptPasswordConn()... -------------------- yes
have_const: checking for PG_DIAG_TABLE_NAME in libpq-fe.h... -------------------- yes
have_header: checking for unistd.h... -------------------- yes
have_header: checking for inttypes.h... -------------------- yes
checking for C99 variable length arrays... -------------------- yes

Regardless of what OS you are running, look at the logs file of the "Makefile" to see what is going on, instead of blindly installing stuff.

In my case, MAC OS, the log file is here:

/Users/za/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/extensions/x86_64-darwin-15/2.3.0-static/pg-1.0.0/mkmf.log

The logs indicated that the make file could not be created because of the following:

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers

Inside the mkmf.log, you will see that it could not find required libraries, to finish the build.

checking for pg_config... no
Can't find the 'libpq-fe.h header
blah blah

After running "brew install postgresql", I can see all required libraries being there:

za:myapp za$ cat /Users/za/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/extensions/x86_64-darwin-15/2.3.0-static/pg-1.0.0/mkmf.log | grep yes

我必须在 CentOS 5.8 上执行此操作。运行 bundle install 不断导致问题，因为我无法强制它使用特定的 PG 版本。

由于依赖性问题（它会删除 php、http 等），我也无法 yum 删除 postgresql postgresql-devel

解决方案？暂时混乱 $PATH 以优先选择更新 pgsql 而不是默认的：

export PATH=/usr/pgsql-9.2/bin:$PATH
bundle install

基本上，使用上述命令，它将在 < 中的命令之前查看 /usr/pgsql-9.2/bin/pg_config代码>/usr/bin/pg_config

I had to do this on CentOS 5.8. Running bundle install kept causing issues since I couldn't force it to use a particular PG version.

I can't yum erase postgresql postgresql-devel either, because of dependency issues (it would remove php, http etc)

The solution? Mess $PATH temporarily to give preference to the update pgsql instead of the default one:

export PATH=/usr/pgsql-9.2/bin:$PATH
bundle install

Basically, with the above commands, it will look at /usr/pgsql-9.2/bin/pg_config before the one in /usr/bin/pg_config

如果您使用 jruby 而不是 ruby​​，那么在安装 pg gem 时也会遇到类似的问题。相反，您需要安装适配器：

gem 'activerecord-jdbcpostgresql-adapter'

If you are using jruby instead of ruby you will have similar issues when installing the pg gem. Instead you need to install the adaptor:

如果您使用的是 MacOS，请检查 mkmf.log 以查看是否需要 xcode 许可证

Run:

sudo xcodebuild -license

并在提示中输入 agree。

另外如果你已经安装了postgres。

where pg_config

然后

gem install pg:1.4.5 -- --with-pg-config='/usr/local/opt/libpq/bin/pg_config'

希望有帮助

If you are using MacOS, check the mkmf.log to see whether it requires an xcode licence

Run:

sudo xcodebuild -license

and type agree in the prompt.

Plus if you have installed postgres.
