Question

如标题中所述，我无法连接到Heroku Postgres数据库。

当我运行命令进行连接时，这是返回的消息。

heroku pg:psql postgresql-metric-xxxxx --app app-name
--> Connecting to postgresql-metric-xxxxx
 !    The local psql command could not be located. For help installing psql, see
 !    https://devcenter.heroku.com/articles/heroku-postgresql#local-setup

但是我已经在运行Windows 10的系统中安装了PostgreSQL。

Answer 1

记得更新你的 PATH 环境变量以添加你安装 Postgres 的 bin 目录。该目录将类似于： C:\Program Files\PostgreSQL<版本>\bin。如果你忘记更新你的 PATH，像 heroku pg:psql 这样的命令将无法工作。

要连接到postgresql，您仍然需要本地安装的postgresql客户端。

在Mac上，您可以使用FROM registry-access-redhat-com.repo.lab.pl.*-*.com/rhel7.5 # CONFIGURE YUM RUN rm -f /etc/yum.repos.d/* ADD resources/yum.repos.d/* /etc/yum.repos.d/ RUN echo "sslverify=false" >> /etc/yum.conf # INSTALL REQUIRED SYSTEM PACKAGES RUN yum install -y python-pip python-devel gcc && yum clean all && rm -rf /var/cache/yum RUN yum install -y wget && yum clean all && rm -rf /var/cache/yum && wget http://repo.lab.pl.alcatel-lucent.com/eden-yum-releases/installation-packages-rpm/python-2.7.15-2.x86_64.rpm RUN yum install -y python-2.7.15-2.x86_64.rpm && yum clean all && rm -rf /var/cache/yum #DOWNLAOD LATEST PIP RUN wget -P /tmp/ https://files.pythonhosted.org/packages/c2/d7/90f34cb0d83a6c5631cf71dfe64cc1054598c843a92b400e55675cc2ac37/pip-18.1-py2.py3-none-any.whl #INSTALL PIP ON PYTHON 2.7.15 RUN LD_LIBRARY_PATH=/usr/local/lib /usr/local/bin/python2.7 /tmp/pip-18.1-py2.py3-none-any.whl/pip install --find-links /tmp --upgrade --no-index /tmp/pip-18.1-py2.py3-none-any.whl # CREATE foo GROUP AND USER RUN groupadd foo RUN useradd -d /home/foo -ms /bin/bash -g foo foo # SETUP BASHRC for foo user COPY file/.bashrc /home/foo COPY file/.bash_profile /home/foo RUN chown foo:foo /home/foo/.bash_profile RUN chown foo:foo /home/foo/.bashrc # SET WORKING DIRECTORY TO /home/foo WORKDIR /home/foo #CREATE VIRTUAL ENVIRONMENT RUN wget -P /tmp/ https://files.pythonhosted.org/packages/e7/16/da8cb8046149d50940c6110310983abb359bbb8cbc3539e6bef95c29428a/setuptools-40.6.2-py2.py3-none-any.whl RUN wget -P /tmp/ https://files.pythonhosted.org/packages/7c/17/9b7b6cddfd255388b58c61e25b091047f6814183e1d63741c8df8dcd65a2/virtualenv-16.1.0-py2.py3-none-any.whl RUN LD_LIBRARY_PATH=/usr/local/lib /usr/local/bin/python2.7 /tmp/pip-18.1-py2.py3-none-any.whl/pip install --find-links /tmp --upgrade --no-index /tmp/virtualenv-16.1.0-py2.py3-none-any.whl RUN LD_LIBRARY_PATH=/usr/local/lib /usr/local/bin/python2.7 /tmp/pip-18.1-py2.py3-none-any.whl/pip install --find-links /tmp --upgrade --no-index /tmp/setuptools-40.6.2-py2.py3-none-any.whl RUN LD_LIBRARY_PATH=/usr/local/lib /usr/local/bin/virtualenv -p /usr/local/bin/python2.7 enet RUN chown -R foo:foo /home/foo/enet RUN export LD_LIBRARY_PATH=/usr/local/lib RUN source /home/foo/enet/bin/activate RUN LD_LIBRARY_PATH=/usr/local/lib /home/foo/enet/bin/python2.7 /tmp/pip-18.1-py2.py3-none-any.whl/pip install --find-links /tmp --upgrade --no-index /tmp/pip-18.1-py2.py3-none-any.whl RUN LD_LIBRARY_PATH=/usr/local/lib /home/foo/enet/bin/python2.7 /tmp/pip-18.1-py2.py3-none-any.whl/pip install scipy RUN LD_LIBRARY_PATH=/usr/local/lib /home/foo/enet/bin/python2.7 /tmp/pip-18.1-py2.py3-none-any.whl/pip install openpyxl RUN LD_LIBRARY_PATH=/usr/local/lib /home/foo/enet/bin/python2.7 /tmp/pip-18.1-py2.py3-none-any.whl/pip install confluent-kafka RUN LD_LIBRARY_PATH=/usr/local/lib /home/foo/enet/bin/python2.7 /tmp/pip-18.1-py2.py3-none-any.whl/pip install cython RUN LD_LIBRARY_PATH=/usr/local/lib /home/foo/enet/bin/python2.7 /tmp/pip-18.1-py2.py3-none-any.whl/pip install pandas RUN LD_LIBRARY_PATH=/usr/local/lib /home/foo/enet/bin/python2.7 /tmp/pip-18.1-py2.py3-none-any.whl/pip install lz4命令进行安装。
在Windows上，您可以找到安装链接here。
在linux上，这实际上取决于您的发行版。但是brew install postgresql命令可能正是您想要的。

也许"pqsl“不在PATH中，所以运行

PATH=%PATH%;C:\Program Files\PostgreSQL\9.2\bin

Heroku无法通过CLI连接到Heroku Postgres
